  • Ajax loaded content , jquery plugins not working

    - by Sylph
    Hello, I have a link that calls the ajax to load content, and after the content is loaded, my jquery function doesn't work anymore Here is my HTML <a href="#" onclick="javascript:makeRequest('content.html','');">Load Content</a> <span id="result"> <table id="myTable" valign="top" class="tablesorter"> <thead> <tr> <th>Title 1</th> <th>Level 1</th> <th>Topics</th> <th>Resources</th> </tr> </thead> <tbody> <tr> <td>Example title 1</td> <td>Example level 1</td> </tr> <tr> <td>Example title 2</td> <td>Example level 2</td> </tr> </tbody> </table> </span> The table is sorted using jquery table sorter plugin from http://tablesorter.com/docs/ After the ajax content is loaded, another set of table with different data will be displayed. However, the sorting doesn't work anymore. Here is my ajax script which is use to load the content : var http_request = false; function makeRequest(url, parameters) { http_request = false; if (window.XMLHttpRequest) { // Mozilla, Safari,... http_request = new XMLHttpRequest(); if (http_request.overrideMimeType) { // set type accordingly to anticipated content type //http_request.overrideMimeType('text/xml'); http_request.overrideMimeType('text/html'); } } else if (window.ActiveXObject) { // IE try { http_request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { http_request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!http_request) { alert('Cannot create XMLHTTP instance'); return false; } http_request.onreadystatechange = alertContents; http_request.open('GET', url + parameters, true); http_request.send(null); } function alertContents() { if (http_request.readyState == 4) { // alert(http_request.status); if (http_request.status == 200) { //alert(http_request.responseText); result = http_request.responseText; document.getElementById('result').innerHTML = result; } else { alert('There was a problem with the request.'); } } } Any idea how I can get the jquery plugins to work after the content is loaded? I have searched and changed the jquery.tablesorter.js click function into live() like this $headers.live("click",function(e) but it doesn't work as well. How can I make the jquery functions to work after the content is loaded? Thank you

  • What are good CLI tools for JSON?

    - by jasonmp85
    General Problem Though I may be diagnosing the root cause of an event, determining how many users it affected, or distilling timing logs in order to assess the performance and throughput impact of a recent code change, my tools stay the same: grep, awk, sed, tr, uniq, sort, zcat, tail, head, join, and split. To glue them all together, Unix gives us pipes, and for fancier filtering we have xargs. If these fail me, there's always perl -e. These tools are perfect for processing CSV files, tab-delimited files, log files with a predictable line format, or files with comma-separated key-value pairs. In other words, files where each line has next to no context. XML Analogues I recently needed to trawl through Gigabytes of XML to build a histogram of usage by user. This was easy enough with the tools I had, but for more complicated queries the normal approaches break down. Say I have files with items like this: <foo user="me"> <baz key="zoidberg" value="squid" /> <baz key="leela" value="cyclops" /> <baz key="fry" value="rube" /> </foo> And let's say I want to produce a mapping from user to average number of <baz>s per <foo>. Processing line-by-line is no longer an option: I need to know which user's <foo> I'm currently inspecting so I know whose average to update. Any sort of Unix one liner that accomplishes this task is likely to be inscrutable. Fortunately in XML-land, we have wonderful technologies like XPath, XQuery, and XSLT to help us. Previously, I had gotten accustomed to using the wonderful XML::XPath Perl module to accomplish queries like the one above, but after finding a TextMate Plugin that could run an XPath expression against my current window, I stopped writing one-off Perl scripts to query XML. And I just found out about XMLStarlet which is installing as I type this and which I look forward to using in the future. JSON Solutions? So this leads me to my question: are there any tools like this for JSON? It's only a matter of time before some investigation task requires me to do similar queries on JSON files, and without tools like XPath and XSLT, such a task will be a lot harder. If I had a bunch of JSON that looked like this: { "firstName": "Bender", "lastName": "Robot", "age": 200, "address": { "streetAddress": "123", "city": "New York", "state": "NY", "postalCode": "1729" }, "phoneNumber": [ { "type": "home", "number": "666 555-1234" }, { "type": "fax", "number": "666 555-4567" } ] } And wanted to find the average number of phone numbers each person had, I could do something like this with XPath: fn:avg(/fn:count(phoneNumber)) Questions Are there any command-line tools that can "query" JSON files in this way? If you have to process a bunch of JSON files on a Unix command line, what tools do you use? Heck, is there even work being done to make a query language like this for JSON? If you do use tools like this in your day-to-day work, what do you like/dislike about them? Are there any gotchas? I'm noticing more and more data serialization is being done using JSON, so processing tools like this will be crucial when analyzing large data dumps in the future. Language libraries for JSON are very strong and it's easy enough to write scripts to do this sort of processing, but to really let people play around with the data shell tools are needed. Related Questions Grep and Sed Equivalent for XML Command Line Processing Is there a query language for JSON? JSONPath or other XPath like utility for JSON/Javascript; or Jquery JSON

  • Is it a missing implementation with JPA implementation of hibernate??

    - by Jegan
    Hi all, On my way in understanding the transaction-type attribute of persistence.xml, i came across an issue / discrepency between hibernate-core and JPA-hibernate which looks weird. I am not pretty sure whether it is a missing implementation with JPA of hibernate. Let me post the comparison between the outcome of JPA implementation and the hibernate implementation of the same concept. Environment Eclipse 3.5.1 JSE v1.6.0_05 Hibernate v3.2.3 [for hibernate core] Hibernate-EntityManger v3.4.0 [for JPA] MySQL DB v5.0 Issue 1.Hibernate core package com.expt.hibernate.core; import java.io.Serializable; public final class Student implements Serializable { private int studId; private String studName; private String studEmailId; public Student(final String studName, final String studEmailId) { this.studName = studName; this.studEmailId = studEmailId; } public int getStudId() { return this.studId; } public String getStudName() { return this.studName; } public String getStudEmailId() { return this.studEmailId; } private void setStudId(int studId) { this.studId = studId; } private void setStudName(String studName) { this.studName = stuName; } private void setStudEmailId(int studEmailId) { this.studEmailId = studEmailId; } } 2.

  • Using Spring as a JPA Container

    - by sdoca
    Hi, I found this article which talks about using Spring as a JPA container: http://java.sys-con.com/node/366275 I have never used Spring before this and am trying to make this work and hope someone can help me. In the article it states that you need to annotate a Spring bean with @Transactional and methods/fields with @PersistenceContext in order to provide transaction support and to inject an entity manager. Is there something the defines a bean as a "Spring Bean"? I have a bean class which implements CRUD operations on entities using generics: @Transactional public class GenericCrudServiceBean implements GenericCrudService { @PersistenceContext(unitName="MyData") private EntityManager em; @Override @PersistenceContext public <T> T create(T t) { em.persist(t); return t; } @Override @PersistenceContext public <T> void delete(T t) { t = em.merge(t); em.remove(t); } ... ... ... @Override @PersistenceContext public List<?> findWithNamedQuery(String queryName) { return em.createNamedQuery(queryName).getResultList(); } } Originally I only had this peristence context annotation: @PersistenceContext(unitName="MyData") private EntityManager em; but had a null em when findWithNamedQuery was invoked. Then I annotated the methods as well, but em is still null (no injection?). I was wondering if this had something to do with my bean not being recognized as "Spring". I have done configuration as best I could following the directions in the article including setting the following in my context.xml file: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns:tx="http://www.springframework.org/schema/tx" tx:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="MyData" /> <property name="dataSource" ref="dataSource" /> <property name="loadTimeWeaver" class="org.springframework.classloading.ReflectiveLoadTimeWeaver" /> <property name="jpaVendorAdapter" ref="jpaAdapter" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <property name="url" value="jdbc:oracle:thin:@localhost:1521:MySID" /> <property name="username" value="user" /> <property name="password" value="password" /> <property name="initialSize" value="3" /> <property name="maxActive" value="10" /> </bean> <bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> <property name="databasePlatform" value="org.eclipse.persistence.platform.database.OraclePlatform" /> <property name="showSql" value="true" /> </bean> <bean class="org.springframework.ormmjpa.support.PersistenceAnnotationBeanPostProcessor" /> <tx:annotation-driven /> </beans> I guessed that these belonged in the context.xml file because the article never specifically said which file is the "application context" file. If this is wrong, please let me know.

  • Jaxb unmarshalls fixml object but all fields are null

    - by DUFF
    I have a small XML document in the FIXML format. I'm unmarshalling them using jaxb. The problem The process complete without errors but the objects which are created are completely null. Every field is empty. The fields which are lists (like the Qty) have the right number of object in them. But the fields of those objects are also null. Setup I've downloaded the FIXML schema from here and I've created the classes with xjc and the maven plugin. They are all in the package org.fixprotocol.fixml_5_0_sp2. I've got the sample xml in a file FIXML.XML <?xml version="1.0" encoding="ISO-8859-1"?> <FIXML> <Batch> <PosRpt> <Pty ID="GS" R="22"/> <Pty ID="01" R="5"/> <Pty ID="6U8" R="28"> <Sub ID="2" Typ="21"/> </Pty> <Pty ID="GS" R="22"/> <Pty ID="6U2" R="2"/> <Instrmt ID="GHPKRW" SecTyp="FWD" MMY="20121018" MatDt="2012-10-18" Mult="1" Exch="GS" PxQteCcy="KJS" FnlSettlCcy="GBP" Fctr="0.192233298" SettlMeth="G" ValMeth="FWDC2" UOM="Ccy" UOMCCy="USD"> <Evnt EventTyp="121" Dt="2013-10-17"/> <Evnt EventTyp="13" Dt="2013-10-17"/> </Instrmt> <Qty Long="0.000" Short="22000000.000" Typ="PNTN"/> <Qty Long="0.000" Short="22000000.000" Typ="FIN"/> <Qty Typ="DLV" Long="0.00" Short="0.00" Net="0.0"/> <Amt Typ="FMTM" Amt="32.332" Ccy="USD"/> <Amt Typ="CASH" Amt="1" Rsn="3" Ccy="USD"/> <Amt Typ="IMTM" Amt="329.19" Ccy="USD"/> <Amt Typ="DLV" Amt="0.00" Ccy="USD"/> <Amt Typ="BANK" Amt="432.23" Ccy="USD"/> </PosRpt> Then I'm calling the unmarshaller with custom event handler which just throws an exception on a parse error. The parsing complete so I know there are no errors being generated. I'm also handling the namespace as suggested here // sort out the file String xmlFile = "C:\\FIXML.XML.xml"; System.out.println("Loading XML File..." + xmlFile); InputStream input = new FileInputStream(xmlFile); InputSource is = new InputSource(input); // create jaxb context JAXBContext jc = JAXBContext.newInstance("org.fixprotocol.fixml_5_0_sp2"); Unmarshaller unmarshaller = jc.createUnmarshaller(); // add event handler so jacB will fail on an error CustomEventHandler validationEventHandler = new CustomEventHandler(); unmarshaller.setEventHandler(validationEventHandler); // set the namespace NamespaceFilter inFilter = new NamespaceFilter("http://www.fixprotocol.org/FIXML-5-0-SP2", true); inFilter.setParent(SAXParserFactory.newInstance().newSAXParser().getXMLReader()); SAXSource source = new SAXSource(inFilter, is); // GO! JAXBElement<FIXML> fixml = unmarshaller.unmarshal(source, FIXML.class); The fixml object is created. In the above sample the Amt array will have five element which matches the number of amts in the file. But all the fields like ccy are null. I've put breakpoints in the classes created by xjc and none of the setters are ever called. So it appears that jaxb is unmarshalling and creating all the correct objects, but it's never calling the setters?? I'm completely stumped on this. I've seen a few posts that suggrest making sure the package.info file that was generated by xjc is in the packags and I've made sure that it's there. There are no working in the IDE about the generated code. Any help much appreciated.

  • jQuery tablesorter sorting not working

    - by jknox
    I'm using jQuery tablesorter plugin to generate dynamically a table from a csv file, and that part is working fine. However whenever i try to sort the table by clicking on the table headers, firebug reports this problem in the console: parsers is undefined return parsers[i].type;\n Initially i though this problem was being caused by the table not being ready after the document loads, so i fixed that by manually calling tablesorter() after my table was rendered from the csv file. this didn't fix the issue though. Also, at the very end of the table, the table is drawn garbled with some gray areas at the end. I suppose this is related to the error above. The code in question is this: <html> <head> <link rel="stylesheet" href="blue/style.css" type="text/css" /> <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript" src="jquery.tablesorter.js"></script> <script type="text/javascript" src="jquery.csv.js"></script> <script type="text/javascript" id="js"> function sortThis() { $("#myTable").tablesorter({ // sortList:[[0,0],[2,1]] }); }; </script> <title>huh!?</title> </head> <body> <table id="myTable" class="tablesorter" cellspacing="1" cellpadding="0" border="0"> <thead> <tr> <th>name</th> <th>type</th> <th>Date</th> </tr> </thead> <tbody> <script type="text/javascript"> $.get('myfile.csv', function(data) { myfile = jQuery.csv()(data) for (var x = 0; x < myfile.length; x++) { str = "<tr>"; for (var y = 0; y < myfile[x].length; y++) { str += "<td>" + myfile[x][y] + "</td>"; } str += "</tr>"; $('#myTable').append(str); } }); sortThis(); </script> </tbody> </table> </body> </html> Thanks in advance for your help.

  • Why doesn't JSF 2.0 RI (Mojarra) scan my class' annotations?

    - by DWoldrich
    I have a War and Jar project in my Eclipse-based JSF project. I have decided to use annotations to declare my FacesConverter, (among a myriad other things), rather than declare it using my faces-config.xml. @FacesConverter(value="passwordFieldStringConverter") public class PasswordFieldStringConverter implements Converter { public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException { try { return arg2.getBytes("UTF-16BE"); } catch(UnsupportedEncodingException uee) { Assert.impossibleException(uee); } return(null); } public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException { try { return new String((byte[]) arg2, "UTF-16BE"); } catch(UnsupportedEncodingException uee) { Assert.impossibleException(uee); } return(null); } } And then I use passwordFieldStringConverter directly in my .xhtml: <?xml version="1.0" encoding="UTF-8" ?> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:sec="http://www.springframework.org/security/facelets/tags"> <ui:composition> <f:view> <f:loadBundle basename="landingPage.bundle" var="bundle" /> <ui:decorate template="/WEB-INF/jsf_helpers/htmlShell.xhtml"> <ui:param name="PageTitleParam" value="#{bundle.pageTitle}" /> <h:form> <h:dataTable var="rowVar" value="#{userListContainer.users}"> <f:facet name="header"><h:outputText value="Users you are currently managing:" /></f:facet> <h:column> <f:facet name="header"> <h:outputText value="Screen Name" /> </f:facet> <h:outputText value="#{rowVar.screenName}" /> </h:column> <h:column> <f:facet name="header"> <h:outputText value="Password" /> </f:facet> <h:outputText value="#{rowVar.password}"> <f:converter converterId="passwordFieldStringConverter" /> </h:outputText> </h:column> </h:dataTable> </h:form> </ui:decorate> </f:view> </ui:composition> </html> JSF is supposed to scan the jars in my War at deployment-time and detect which classes have annotations on them (and auto-configure the application accordingly). My problem is that JSF is apparently not detecting the classes I have which sport annotations. The War project has all of my .xhtml files as well as the project's faces-config.xml, my Jar project has all of my faces related Java code (action beans, managed beans, custom converters, etc.)

  • Reading serialised object from file

    - by nico
    Hi everyone. I'm writing a little Java program (it's an ImageJ plugin, but the problem is not specifically ImageJ related) and I have some problem, most probably due to the fact that I never really programmed in Java before... So, I have a Vector of Vectors and I'm trying to save it to a file and read it. The variable is defined as: Vector <Vector <myROI> > ROIs = new Vector <Vector <myROI> >(); where myROI is a class that I previously defined. Now, to write the vector to a file I use: void saveROIs() { SaveDialog save = new SaveDialog("Save ROIs...", imp.getTitle(), ".xroi"); String name = save.getFileName(); if (name == null) return; String dir = save.getDirectory(); try { FileOutputStream fos = new FileOutputStream(dir+name); ObjectOutputStream oos = new ObjectOutputStream(fos); oos.writeObject(ROIs); oos.close(); } catch (Exception e) { IJ.log(e.toString()); } } This correctly generates a binary file containing (I suppose) the object ROIs. Now, I use a very similar code to read the file: void loadROIs() { OpenDialog open = new OpenDialog("Load ROIs...", imp.getTitle(), ".xroi"); String name = open.getFileName(); if (name == null) return; String dir = open.getDirectory(); try { FileInputStream fin = new FileInputStream(dir+name); ObjectInputStream ois = new ObjectInputStream(fin); ROIs = (Vector <Vector <myROI> >) ois.readObject(); // This gives error ois.close(); } catch (Exception e) { IJ.log(e.toString()); } } But this function does not work. First, I get a warning: warning: [unchecked] unchecked cast found : java.lang.Object required: java.util.Vector<java.util.Vector<myROI>> ROIs = (Vector <Vector <myROI> >) ois.readObject(); ^ I Googled for that and see that I can suppress by prepending @SuppressWarnings("unchecked"), but this just makes things worst, as I get an error: <identifier> expected ROIs = (Vector <Vector <myROI> >) ois.readObject(); ^ In any case, if I omit @SuppressWarnings and ignore the warning, the object is not read and an exception is thrown java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: myROI Again Google tells me myROI needs to implements Serializable. I tried just adding implements Serializable to the class definition, but it is not sufficient. Can anyone give me some hints on how to procede in this case? Also, how to get rid of the typecast warning?

  • Running code when all threads are finished processing.

    - by rich97
    Quick note: Java and Android noob here, I'm open to you telling me I'm stupid (as long as you tell me why.) I have an android application which requires me start multiple threads originating from various classes and only advance to the next activity once all threads have done their job. I also want to add a "failsafe" timeout in case one the the threads takes too long (HTTP request taking too long or something.) I searched Stack Overflow and found a post saying that I should create a class to keep a running total of open threads and then use a timer to poll for when all the threads are completed. I think I've created a working class to do this for me, it's untested as of yet but has no errors showing in eclipse. Is this a correct implementation? Are there any APIs that I should be made aware of (such as classes in the Java or Android APIs that could be used in place of the abstract classes at the bottom of the class?) package com.dmp.geofix.libs; import java.util.ArrayList; import java.util.Iterator; import java.util.Timer; import java.util.TimerTask; public class ThreadMonitor { private Timer timer = null; private TimerTask timerTask = null; private OnSuccess onSuccess = null; private OnError onError = null; private static ArrayList<Thread> threads; private final int POLL_OPEN_THREADS = 100; private final int TIMEOUT = 10000; public ThreadMonitor() { timerTask = new PollThreadsTask(); } public ThreadMonitor(OnSuccess s) { timerTask = new PollThreadsTask(); onSuccess = s; } public ThreadMonitor(OnError e) { timerTask = new PollThreadsTask(); onError = e; } public ThreadMonitor(OnSuccess s, OnError e) { timerTask = new PollThreadsTask(); onSuccess = s; onError = e; } public void start() { Iterator<Thread> i = threads.iterator(); while (i.hasNext()) { i.next().start(); } timer = new Timer(); timer.schedule(timerTask, 0, POLL_OPEN_THREADS); } public void finish() { Iterator<Thread> i = threads.iterator(); while (i.hasNext()) { i.next().interrupt(); } threads.clear(); timer.cancel(); } public void addThread(Thread t) { threads.add(t); } public void removeThread(Thread t) { threads.remove(t); t.interrupt(); } class PollThreadsTask extends TimerTask { private int timeElapsed = 0; @Override public void run() { timeElapsed += POLL_OPEN_THREADS; if (timeElapsed <= TIMEOUT) { if (threads.isEmpty() == false) { if (onSuccess != null) { onSuccess.run(); } } } else { if (onError != null) { onError.run(); } finish(); } } } public abstract class OnSuccess { public abstract void run(); } public abstract class OnError { public abstract void run(); } }

  • Nginx & Apache Cannot get try_files to work with permalinks

    - by tcherokee
    I have been working on this for the past two weeks not and for some reason I cannot seem to get nginx's try_files to work with my wordpress permalinks. I am hoping someone will be able to tell me where I am going wrong and also hopefully tell me if I made any major errors with my configurations as well (I am an nginx newbie... but learning :) ). Here are my Configuration files nginx.conf user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## # Defines the cache log format, cache log location # and the main access log location. log_format cache '***$time_local ' '$upstream_cache_status ' 'Cache-Control: $upstream_http_cache_control ' 'Expires: $upstream_http_expires ' '$host ' '"$request" ($status) ' '"$http_user_agent" ' ; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } mydomain.com.conf server { listen 123.456.78.901:80; # IP goes here. server_name www.mydomain.com mydomain.com; #root /var/www/mydomain.com/prod; index index.php; ## mydomain.com -> www.mydomain.com (301 - Permanent) if ($host !~* ^(www|dev)) { rewrite ^/(.*)$ $scheme://www.$host/$1 permanent; } # Add trailing slash to */wp-admin requests. rewrite /wp-admin$ $scheme://$host$uri/ permanent; # All media (including uploaded) is under wp-content/ so # instead of caching the response from apache, we're just # going to use nginx to serve directly from there. location ~* ^/(wp-content|wp-includes)/(.*)\.(jpg|png|gif|jpeg|css|js|m$ root /var/www/mydomain.com/prod; } # Don't cache these pages. location ~* ^/(wp-admin|wp-login.php) { proxy_pass http://backend; } location / { if ($http_cookie ~* "wordpress_logged_in_[^=]*=([^%]+)%7C") { set $do_not_cache 1; } proxy_cache_key "$scheme://$host$request_uri $do_not_cache"; proxy_cache main; proxy_pass http://backend; proxy_cache_valid 30m; # 200, 301 and 302 will be cached. # Fallback to stale cache on certain errors. # 503 is deliberately missing, if we're down for maintenance # we want the page to display. #try_files $uri $uri/ /index.php?q=$uri$args; #try_files $uri =404; proxy_cache_use_stale error timeout invalid_header http_500 http_502 http_504 http_404; } # Cache purge URL - works in tandem with WP plugin. # location ~ /purge(/.*) { # proxy_cache_purge main "$scheme://$host$1"; # } # No access to .htaccess files. location ~ /\.ht { deny all; } } # End server gzip.conf # Gzip Configuration. gzip on; gzip_disable msie6; gzip_static on; gzip_comp_level 4; gzip_proxied any; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; proxy.conf # Set proxy headers for the passthrough proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; add_header X-Cache-Status $upstream_cache_status; backend.conf upstream backend { # Defines backends. # Extracting here makes it easier to load balance # in the future.

  • Events do not propagate from a child element?

    - by Legend
    I was playing around with the Swipe jQuery plugin on my iPod Touch and Android devices. The following works: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('body').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </body> </html> But if I have something like this: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('#wrapper').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="wrapper"> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </div> </body> </html> Notice the "wrapper" div around the containers. Now, when I swipe on the div element, I was expecting it to actually trigger the event. This works in iPod touch as expected but does not work on my Android device unless I randomly start swiping everywhere until I happen to swipe on that small wrapper div element itself. I am not sure how to explain this but hink of it as sending events to the wrapper div itself. Both use the WebKit engine. Can someone tell me if I am doing something wrong?

  • What's a clean way to have the server return a JavaScript function which would then be invoked?

    - by Khnle
    My application is architected as a host of plug-ins that have not yet been written. There's a long reason for this, but with each new year, the business logic will be different and we don't know what it will be like (Think of TurboTax if that helps). The plug-ins consist of both server and client components. The server components deals with business logic and persisting the data into database tables which will be created at a later time as well. The JavaScript manipulates the DOM for the browsers to render afterward. Each plugin lives in a separate assembly, so that they won't disturb the main application, i.e., we don't want to recompile the main application. Long story short, I am looking for a way to return JavaScript functions to the client from an Ajax get request, and execute these JavaScript functions (which are just returned). Invoking a function in Javascript is easy. The hard part is how to organize or structure so that I won't have to deal with maintenance problem. So concat using StringBuilder to end up with JavaScript code as a result of calling toString() from the string builder object is out of the question. I want to have no difference between writing JavaScript codes normally and writing Javascript codes for this dynamic purpose. An alternative is to manipulate the DOM on the server side, but I doubt that it would be as elegantly as using jQuery on the client side. I am open for a C# library that supports chainable calls like jQuery that also manipulates the DOM too. Do you have any idea or is it too much to ask or are you too confused? Edit1: The point is to avoid recompiling, hence the plug-ins architecture. In some other parts of the program, I already use the concept of dynamically loading Javascript files. That works fine. What I am looking here is somewhere in the middle of the program when an Ajax request is sent to the server. Edit 2: To illustrate my question: Normally, you would see the following code. An Ajax request is sent to the server, a JSON result is returned to the client which then uses jQuery to manipulate the DOM (creating tag and adding to the container in this case). $.ajax({ type: 'get', url: someUrl, data: {'': ''}, success: function(data) { var ul = $('<ul>').appendTo(container); var decoded = $.parseJSON(data); $.each(decoded, function(i, e) { var li = $('<li>').text(e.FIELD1 + ',' + e.FIELD2 + ',' + e.FIELD3); ul.append(li); }); } }); The above is extremely simple. But next year, what the server returns is totally different and how the data to be rendered would also be different. In a way, this is what I want: var container = $('#some-existing-element-on-the-page'); $.ajax({ type: 'get', url: someUrl, data: {'': ''}, success: function(data) { var decoded = $.parseJSON(data); var fx = decoded.fx; var data = decode.data; //fx is the dynamic function that create the DOM from the data and append to the existing container fx(container, data); } }); I don't need to know, at this time what data would be like, but in the future I will, and I can then write fx accordingly.

  • can't implement jquery jScrollPane to replace browser's scrollbars

    - by Zack
    I am trying to replace browser's scrollbars with jScrollPane (jQuery), it won't work. Here are two attempts to implement it: a basic attempt, and an attempt to imitate the full page demo for jScrollPane. I've been trying everything I could think of to figure out what didn't work, but couldn't. here is my code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title></title> <!-- styles needed by jScrollPane --> <link type="text/css" href="style/jquery.jscrollpane.css" rel="stylesheet" media="all" /> <style type="text/css" id="page-css"> /* Styles specific to this particular page */ html { overflow: auto; } #full-page-container { overflow: auto; } .scroll-pane { width: 100%; height: 200px; overflow: auto; } .horizontal-only { height: auto; max-height: 200px; } </style> <!-- latest jQuery direct from google's CDN --> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <!-- the mousewheel plugin --> <script type="text/javascript" src="script/jquery.mousewheel.js"></script> <!-- the jScrollPane script --> <script type="text/javascript" src="script/jquery.jscrollpane.min.js"></script> <script type="text/javascript" id="sourcecode"> $(function () { var win = $(window); // Full body scroll var isResizing = false; win.bind( 'resize', function () { if (!isResizing) { isResizing = true; var container = $('#full-page-container'); // Temporarily make the container tiny so it doesn't influence the // calculation of the size of the document container.css( { 'width': 1, 'height': 1 } ); // Now make it the size of the window... container.css( { 'width': win.width(), 'height': win.height() } ); isResizing = false; container.jScrollPane( { 'showArrows': true } ); } } ).trigger('resize'); // Workaround for known Opera issue which breaks demo (see // http://jscrollpane.kelvinluck.com/known_issues.html#opera-scrollbar ) $('body').css('overflow', 'hidden'); // IE calculates the width incorrectly first time round (it // doesn't count the space used by the native scrollbar) so // we re-trigger if necessary. if ($('#full-page-container').width() != win.width()) { win.trigger('resize'); } }); </script> </head> <body> <div id="full-page-container"> This is the most basic implementation of jScrollPane I could create, if I am not wrong this has all it should take, yet it doesn't work. a little lorem ipsum to make the scrollbars show up: [here come's lot's of lorem ipsum text in the actual page...] </div> </body> </html> The other option is the same, with a link to demo.css and demo.js.

    - by SHAKTI
    I'm not expert about css menus. But I know basic system to make css menu. I used this system before and works, but this time it is not working. The site is http://www.uniethos.com. Please check this site This menu works with all other latest Browsers. But not with IE 6 & 7. I know IE6 don't support hover except anchor. So before I was using Whatever Hover. But this time it is not working and even with IE7. I don't know why its happening. May be there could be some problem with my css. Please check the css. If you don't have IE 6 or 7 installed you can run one from http://spoon.net/browsers/. Require to install one plugin. The CSS I'm using for the menu is .glossymenu{ background: #B4B3B3; height: 30px; width: 100%; padding: 0; margin: 0; display:inline-block; position:relative; } .glossymenu ul { list-style: none; padding: 0px; margin: 0; padding-left: 0px; } .glossymenu li ul { display:none; position:absolute; width: 80%; top:30px; left:0px; background-color:#5B0C10; border:0px; z-index: 99; } .glossymenu li li a { padding: 0px 10px 0px 10px; } .glossymenu li li a:hover { background : #871016; } .glossymenu li{ float:left; padding: 0; } .glossymenu li a{ float: left; display:block; position:relative; color:#FFF; text-decoration: none; font-family: sans-serif; font-size: 13px; font-weight: bold; padding:0 0 0 16px; /*Padding to accomodate left tab image.

  • jQuery not executed on page load

    - by Arild Sandberg
    I'm building an ajax upload with an editing function (rotate, zoom and crop), and I'm using guillotine by matiasgagliano (https://github.com/matiasgagliano/guillotine) for this. My problem is that after upload the user get redirected to the editing page through ajax, but when landing on that page I always have to refresh the page in browser for the image to load. I've tried auto-reloading, both through js and php, but that doesn't help, neither does adding a button to load the same url again. Only refresh from browser button (tested in several browsers) works. I've tried implementing jquery.turbolinks, but that stopped guillotine functions from working. I'm loading the guillotine.js in head section after jQuery, and have the function in bottom before body tag. Any tip or help would be appreciated. Thx Here is some of the code: HTML: <div class='frame'> <img id="id_picture" src="identifications/<?php echo $id_url; ?>" alt="id" /> </div> <div id='controls'> <a href='javascript:void(0)' id='rotate_left' title='<?php echo $word_row[434]; ?>'><i class='fa fa-rotate-left'></i></a> <a href='javascript:void(0)' id='zoom_out' title='<?php echo $word_row[436]; ?>'><i class='fa fa-search-minus'></i></a> <a href='javascript:void(0)' id='fit' title='<?php echo $word_row[438]; ?>'><i class='fa fa-arrows-alt'></i></a> <a href='javascript:void(0)' id='zoom_in' title='<?php echo $word_row[437]; ?>'><i class='fa fa-search-plus'></i></a> <a href='javascript:void(0)' id='rotate_right' title='<?php echo $word_row[435]; ?>'><i class='fa fa-rotate-right'></i></a> </div> Js: <script type='text/javascript'> jQuery(function() { var picture = $('#id_picture'); picture.guillotine({ width: 240, height: 180 }); picture.on('load', function(){ // Initialize plugin (with custom event) picture.guillotine({eventOnChange: 'guillotinechange'}); // Display inital data var data = picture.guillotine('getData'); for(var key in data) { $('#'+key).html(data[key]); } // Bind button actions $('#rotate_left').click(function(){ picture.guillotine('rotateLeft'); }); $('#rotate_right').click(function(){ picture.guillotine('rotateRight'); }); $('#fit').click(function(){ picture.guillotine('fit'); }); $('#zoom_in').click(function(){ picture.guillotine('zoomIn'); }); $('#zoom_out').click(function(){ picture.guillotine('zoomOut'); }); $('#process').click(function(){ $.ajax({ type: "POST", url: "scripts/process_id.php?id=<?php echo $emp_id; ?>&user=<?php echo $user; ?>", data: data, cache: false, success: function(html) { window.location = "<?php echo $finish_url; ?>"; } }); }); // Update data on change picture.on('guillotinechange', function(ev, data, action) { data.scale = parseFloat(data.scale.toFixed(4)); for(var k in data) { $('#'+k).html(data[k]); } }); }); }); </script>

  • Problems with createImage(int width, int height)

    - by Jonathan
    I have the following code, which is run every 10ms as part of a game: private void gameRender() { if(dbImage == null) { //createImage() returns null if GraphicsEnvironment.isHeadless() //returns true. (java.awt.GraphicsEnvironment) dbImage = createImage(PWIDTH, PHEIGHT); if(dbImage == null) { System.out.println("dbImage is null"); //Error recieved return; } else dbg = dbImage.getGraphics(); } //clear the background dbg.setColor(Color.white); dbg.fillRect(0, 0, PWIDTH, PHEIGHT); //draw game elements... if(gameOver) { gameOverMessage(dbg); } } The problem is that it enters the if statement which checks for the Image being null, even after I attempt to define the image. I looked around, and it seems that createImage() will return null if GraphicsEnvironment.isHeadless() returns true. I don't understand exactly what the isHeadless() method's purpose is, but I thought it might have something to do with the compiler or IDE, so I tried on two, both of which get the same error (Eclipse, and BlueJ). Anyone have any idea what the source of the error is, and how I might fix it? Thanks in advance Jonathan ................................................................... EDIT: I am using java.awt.Component.createImage(int width, int height). The purpose of this method is to ensure the creation of, and edit an Image that will contain the view of the player of the game, that will later be drawn to the screen by means of a JPanel. Here is some more code if this helps at all: public class Sim2D extends JPanel implements Runnable { private static final int PWIDTH = 500; private static final int PHEIGHT = 400; private volatile boolean running = true; private volatile boolean gameOver = false; private Thread animator; //gameRender() private Graphics dbg; private Image dbImage = null; public Sim2D() { setBackground(Color.white); setPreferredSize(new Dimension(PWIDTH, PHEIGHT)); setFocusable(true); requestFocus(); //Sim2D now recieves key events readyForTermination(); addMouseListener( new MouseAdapter() { public void mousePressed(MouseEvent e) { testPress(e.getX(), e.getY()); } }); } //end of constructor private void testPress(int x, int y) { if(!gameOver) { gameOver = true; //end game at mousepress } } //end of testPress() private void readyForTermination() { addKeyListener( new KeyAdapter() { public void keyPressed(KeyEvent e) { int keyCode = e.getKeyCode(); if((keyCode == KeyEvent.VK_ESCAPE) || (keyCode == KeyEvent.VK_Q) || (keyCode == KeyEvent.VK_END) || ((keyCode == KeyEvent.VK_C) && e.isControlDown()) ) { running = false; //end process on above list of keypresses } } }); } //end of readyForTermination() public void addNotify() { super.addNotify(); //creates the peer startGame(); //start the thread } //end of addNotify() public void startGame() { if(animator == null || !running) { animator = new Thread(this); animator.start(); } } //end of startGame() //run method for world public void run() { while(running) { long beforeTime, timeDiff, sleepTime; beforeTime = System.nanoTime(); gameUpdate(); //updates objects in game (step event in game) gameRender(); //renders image paintScreen(); //paints rendered image to screen timeDiff = (System.nanoTime() - beforeTime) / 1000000; sleepTime = 10 - timeDiff; if(sleepTime <= 0) //if took longer than 10ms { sleepTime = 5; //sleep a bit anyways } try{ Thread.sleep(sleepTime); //sleep by allotted time (attempts to keep this loop to about 10ms) } catch(InterruptedException ex){} beforeTime = System.nanoTime(); } System.exit(0); } //end of run() private void gameRender() { if(dbImage == null) { dbImage = createImage(PWIDTH, PHEIGHT); if(dbImage == null) { System.out.println("dbImage is null"); return; } else dbg = dbImage.getGraphics(); } //clear the background dbg.setColor(Color.white); dbg.fillRect(0, 0, PWIDTH, PHEIGHT); //draw game elements... if(gameOver) { gameOverMessage(dbg); } } //end of gameRender() } //end of class Sim2D Hope this helps clear things up a bit, Jonathan

  • Logcat error: "addView(View, LayoutParams) is not supported in AdapterView" in a ListView

    - by HacKreatorz
    I'm doing an aplication for Android and something I need is that it shows a list of all files and directories in the SD Card and it has to be able to move through the different directories. I found a good tutorial in anddev: http://bit.ly/h4GyFC I modified a few things so the aplication moves in the SD Card and not in Android root Directories but the rest is mostly the same. This is my xml file for the activity: <?xml version="1.0" encoding="utf-8"?> <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" /> </ListView> And this is the code for the Activity: import hackreatorz.cifrador.R; import java.io.File; import java.util.ArrayList; import android.app.ListActivity; import android.content.res.Configuration; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast; public class ArchivosSD extends ListActivity { private ArrayList<String> directoryEntries = new ArrayList<String>(); private File currentDirectory = new File("/sdcard/"); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); browseToSD(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } private void browseToSD() { browseTo(new File("/sdcard/")); } private void upOneLevel() { if(this.currentDirectory.getParent() != null) this.browseTo(this.currentDirectory.getParentFile()); } private void browseTo(final File directory) { if (directory.isDirectory()) { this.currentDirectory = directory; fill(directory.listFiles()); } else { Toast.makeText(ArchivosSD.this, this.directoryEntries.get(this.getSelectedItemPosition()), Toast.LENGTH_SHORT).show(); } } private void fill(File[] files) { this.directoryEntries.clear(); this.directoryEntries.add(getString(R.string.current_dir)); if(this.currentDirectory.getParent() != null) this.directoryEntries.add(getString(R.string.up_one_level)); int currentPathStringLength = (int) this.currentDirectory.getAbsoluteFile().length(); for (File file : files) { this.directoryEntries.add(file.getAbsolutePath().substring(currentPathStringLength)); } setListAdapter(new ArrayAdapter<String>(this, R.layout.archivos_sd, this.directoryEntries)); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { int selectionRowID = (int) this.getSelectedItemPosition(); String selectedFileString = this.directoryEntries.get(selectionRowID); if (selectedFileString.equals(".")) { this.browseToSD(); } else if(selectedFileString.equals("..")) { this.upOneLevel(); } else { File clickedFile = null; clickedFile = new File(this.currentDirectory.getAbsolutePath() + this.directoryEntries.get(selectionRowID)); if(clickedFile != null) this.browseTo(clickedFile); } } } I don't get any errores in Eclipse, but I get a Force Close when running the aplication on my phone and when I look at Logcat I see the following: 01-01 23:30:29.858: ERROR/AndroidRuntime(14911): FATAL EXCEPTION: main *01-01 23:30:29.858: ERROR/AndroidRuntime(14911): java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView* I don't have a clue what to do, I've looked up in Google and I didn't find anything and I did the same at stackoverflow. This is my first aplication in Java and for Android so I'm a real n00b and if the answer was there, I didn't understand it so I would really apreciate if you could explain what I should do to fix this error and why. Thanks for everything in advanced.

  • Using javascript, show a certain amount of divs based on an answer

    - by Adam
    I'm building a form that first asks if you have 'foo'. If the answer is 'Yes', a div appears and asks 'How many foo do you have'? Based on the quantity answered, I'd like to show only that many divs. Thus if the user answers 1, only the first div will show. If they answer three, the first three will show. I have it set so that if the user answers no, the question of the amount remains hidden, but if they answer yes, they would be prompted for the quantity. This is what I've got so far... <script type="text/javascript"> $(document).ready(function(){ $(window).load(function() { $('#amt_of_foo,.foo_panels').hide(); }); $('#yes_foo').click(function() { $('#amt_of_foo').show(); }); $('#no_foo').click(function() { $('.foo_panels,#amt_of_foo').hide(); }); }); </script> </head> <body> <ul> <li> <div class="panel section_panel"> <h2>Questions About Your Foo</h2> <span>Do you have foo?:</span> <input type="radio" name="foo" id="no_foo" /> No <br /> <input type="radio" name="foo" id="yes_foo" /> Yes:</span></span> <span id="amt_of_foo"> <span>How many foo do you have?:</span> <span><input id="qty_of_foo" type="text" size="5" /> </span> </span> </div> </li> <!--answered yes to foo, and entered amount--> <div class="foo_panels"> <li> <li> <div class="panel foo_1"> <h1>First foo's information</h1> <span>Foo name:&nbsp;<input type="text" size="20" /></span> </div> </li> <li> <div class="panel foo_2"> <h1>Second foo's information</h1> <span>Foo name:&nbsp;<input type="text" size="20" /></span> </div> </li> <li> <div class="panel foo_3"> <h1>Third foo's information</h1> <span>Foo name:&nbsp;<input type="text" size="20" /></span> </div> </li> </div> <!--answered no to foo--> <li> <div class="panel"> <h1>Next Question, if no foo</h1> </div> </li> </ul> The ul is used for a jQuery 'slider' plugin. the 'panel' class is used for global css.

  • Trying to reinvent the wheel of StackOverflow to have a good learning experience. Need some suggesti

    - by Legend
    I want to learn and am not able to do it unless I have a real "mission" to complete. SO is my favorite and I can't imagine a better experience than actually recreating it but not in ASP. I'd like to use PHP+MySQL+jQuery. So far, I have been a self-taught programmer but I would like to master one paradigm that forces you to adhere to the standards. For instance, recently, jQuery forced me to use some "rules". The plugins were supposed to be written in a particular way and that's it. When I started off, everything seemed like Greek and Latin but when I finished a very small plugin, I felt really happy because it forced me to program in a certain way. I am looking for something like this only in a larger project. I've heard a lot about MVC and all but I am confused about the various frameworks out there. Zend seems awesome but looks heavy at the same time and also requires you to have a lot more control over the web-server whereas CakePHP is a good and a fast framework that needs only little control. Do I use one of these or just write my own MVC? I have the following goals: Goals: Site should be fast - I know this depends on my coding skills but I will learn on my way. The framework itself should not slow me down) Setting up the site should not require you to use command-line - This requirement is ok during development. But some frameworks like Symphony require you to initialize certain things through command-line Should support pluggable modules - For instance, if I want to be able to use the FCK editor, I should be able to organize things in a good way. Should be possible to extend - For instance, SO is mainly a Q&A site but I should be able to logically extend it into an Idea Management System (optional but I'm curious). This goes more into code re-usability I guess. I am comfortable with MySQL so I should be done with database design etc. with some serious effort. As for PHP, I can write code on my own but haven't really used any frameworks that much. jQuery, I started off recently and love it. I would be glad if someone can guide me during these initial steps. Precisely, when designing something like SO, I have the following questions: Do I use a framework? If yes, should it be MVC? If MVC, which one is a good and a scalable one? (I'd love something like jQuery that will not die anytime soon) How do I balance the functionality? The same logic can sometimes be made server centric or client centric. (more Ajax?). Is it a good idea to make a heavy javascript site considering the recent advances on client-side JS processing? Just in case anyone is wondering, I am not interested in commercializing any of this. I need a reason to learn something :)

  • jQuery autocomplete. Doesn't reveal existing matches.

    - by Alexander
    Hello fellow engineers. I have come across a problem I just can't solve. I am using autocomplete plugin for jQuery on an input. The HTML looks something like this: <tr id="row_house" class="no-display"> <td class="col_num">4</td> <td class="col_label">House Number</td> <td class="col_data"> <input type="text" title="House Number" name="house" id="house"/> <button class="pretty_button ui-state-default ui-corner-all button-finish">Get house info</button> </td> </tr> I am sure that this is the only id="house" field. Other fields that are before this one work fine with autocomplete, and it's basically the same algorithm (other variables, other data, other calls). So why doesn't it work like it should work with the following init. code: $("#house").autocomplete(["1/4","6","6/1","6/4","8","8/1","8/5","10","10/1","10/3","10/4","12","12/1","12/5","12/6","14","14/1","15","15/1","15/2","15/4","15/5","16","16/1","16/2","16/21","16/2B","16/3","16/4","17","17/1","17/2","17/4","17/5","17/6","17/7","17/8","18","18/1","18/2","18/3","18/5","18/95","19","19/1","19/2","19/3","19/4","19/5","19/6","19/7","19/8","20","20/1","20/2","20/3","20/4","21","21/1","21/2","21/3","21/4","22","22/9","23","23/2","23/4","24","24/1","24/2","24/3","24/A","25","25/1","25/10","25/2","25/4","25/5","25/6","25/7","25/8","25/9","26","26/1","26/6","27","27/2","28","28/1","29","29/2","29/3","29/4","30","30/1","30/2","30/3","31","31/1","31/3","32/A","33","34","34/1","34/11","34/2","34/3","35","35/1","35/2","35/4","36","36/1","36/A","37","37/1","37/2","38","38/1","38/2","39/1","39/2","39/3","39/4","40","40/1","41","41/2","42","43","44","45","45/1","45/10","45/11","45/12","45/13","45/14","45/15","45/16","45/17","45/2","45/3","45/6","45/7","45/8","45/9","46","47","47/2","49","49/1","50","51","51/1","51/2","52","53","54","55/7","66","109","122","190/8","412"], {minChars:1, mustMatch:true}).result(function(event, result, formatted) { var found=false; for(var index=0; index<HChouses.length; index++) //HChouses is the same array used for init, but each entry is paired with a database ID. if(HChouses[index][0]==result) { found=true; HChouseId=HChouses[index][1]; $("#row_house .button-finish").click(function() { QueryServer("HouseConnect","FillData",true,HChouseId); //this performs an AJAX request }); break; } if(!found) $("#row_house .button-finish").unbind("click"); }); Each time I start typing (say I press the "1" button), the text appears and gets deleted instantly. Rarely at all after repeated presses I get the list (although much shorter than it should be) But if after that I press the second digit, the whole thing disappears again. P.S. I use Firefox 3.6.3 for development.

  • JQuery Checkbox with Textbox Validation

    - by Volrath
    I am using Jorn's validation plugin. I have a a group of checkboxes beside a group of textboxes. The textboxes are disabled by default and will enable when the matching checkbox is checked. At least 1 checkbox has to be checked which is not a problem. However, when I check more than 2 checkboxes only 1 textbox validates. The form still submits even when the second checkbox is empty. $count = 0; while($row = mysql_fetch_array($rs)) { ?> <tr> <td> <label> <input type="checkbox" name="tDays[]" id="tDays<?php echo $count; ?>" value="<?php echo $row['promoDayID'];?>" onClick="enableTxt();" <?php if((isset($arrTDays) && in_array_THours($row['promoDayID'], $arrTDays)) || (!empty($arrSelectedTHours) && in_array_THours($row['promoDayID'], $arrSelectedTHours))) { echo "checked='checked'"; }?> validate="required:true" /> <?php echo $row['promoDay'];?>: </label> </td> <td align="right"> <input type="textbox" size="45" style="font-size:12px" name="tHours[]" id="tHours<?php echo $count; ?>" <?php if(isset($arrTDays) && in_array_THours($row['promoDayID'], $arrTDays)) { echo "value='" .getHours($row['promoDayID'], $arrTDays) ."'"; } elseif (!empty($arrSelectedTHours) && in_array_THours($row['promoDayID'], $arrSelectedTHours)) { echo "value='" .getHours($row['promoDayID'], $arrSelectedTHours). "'"; } else { echo "value='' disabled='disabled'"; }?> class="required" /> <label for="tHours[]" class="error" id="tHourserror<?php echo $count; ?>">Please enter the Trading Hour.</label> </td> </tr> <?php $count++; }//while ?> This is done using javascript: function enableTxt() { for (i = 0; i <= 7; i++) { if (document.getElementById("tDays" + i) != null && document.getElementById("tDays" + i).checked == true) { document.getElementById('tHours' + i).disabled = false; document.getElementById('tHourserror' + i).style.visibility = "visible"; } else if (document.getElementById("tDays" + i) != null) { document.getElementById('tHours' + i).disabled = "disabled"; document.getElementById('tHours' + i).value = ""; document.getElementById('tHourserror' + i).style.visibility = "hidden"; } } } Please kindly advise in detail as to how this problem can be solved. I am fairly weak in JQuery.

  • Objective-C vs JavaScript loop performance

    - by micadelli
    I have a PhoneGap mobile application that I need to generate an array of match combinations. In JavaScript side, the code hanged pretty soon when the array of which the combinations are generated from got a bit bigger. So, I thought I'll make a plugin to generate the combinations, passing the array of javascript objects to native side and loop it there. To my surprise the following codes executes in 150 ms (JavaScript) whereas in native side (Objective-C) it takes ~1000 ms. Does anyone know any tips for speeding up those executing times? When players exceeds 10, i.e. the length of the array of teams equals 252 it really gets slow. Those execution times mentioned above are for 10 players / 252 teams. Here's the JavaScript code: for (i = 0; i < GAME.teams.length; i += 1) { for (j = i + 1; j < GAME.teams.length; j += 1) { t1 = GAME.teams[i]; t2 = GAME.teams[j]; if ((t1.mask & t2.mask) === 0) { GAME.matches.push({ Team1: t1, Team2: t2 }); } } } ... and here's the native code: NSArray *teams = [[NSArray alloc] initWithArray: [options objectForKey:@"teams"]]; NSMutableArray *t = [[NSMutableArray alloc] init]; int mask_t1; int mask_t2; for (NSInteger i = 0; i < [teams count]; i++) { for (NSInteger j = i + 1; j < [teams count]; j++) { mask_t1 = [[[teams objectAtIndex:i] objectForKey:@"mask"] intValue]; mask_t2 = [[[teams objectAtIndex:j] objectForKey:@"mask"] intValue]; if ((mask_t1 & mask_t2) == 0) { [t insertObject:[teams objectAtIndex:i] atIndex:0]; [t insertObject:[teams objectAtIndex:j] atIndex:1]; /* NSArray *newCombination = [[NSArray alloc] initWithObjects: [teams objectAtIndex:i], [teams objectAtIndex:j], nil]; */ [combinations addObject:t]; } } } ... the array in question (GAME.teams) looks like this: { count = 2; full = 1; list = ( { index = 0; mask = 1; name = A; score = 0; }, { index = 1; mask = 2; name = B; score = 0; } ); mask = 3; name = A; }, { count = 2; full = 1; list = ( { index = 0; mask = 1; name = A; score = 0; }, { index = 2; mask = 4; name = C; score = 0; } ); mask = 5; name = A; },

  • How To Run XP Mode in VirtualBox on Windows 7 (sort of)

    - by Matthew Guay
    A few weeks ago we showed you how to run XP Mode on a Windows 7 computer without Hardware Virtualization using VMware. Some of you have been asking if it can be done in Virtual Box as well. The answer is “Yes!” and here we’ll show you how. Editor Update: Apparently there isn’t a way to activate XP Mode through VirtualBox using this method. You will however, be able to run it for 30 days. We have a new updated article on how to Install XP Mode with VirtualBox Using the VMLite Plugin.   Earlier we showed you how to run XP mode on windows 7 machines without hardware virtualization capability. Since then, a lot of you have been asking to a write up a tutorial about doing the same thing using VirtualBox.  This makes it another great way to run XP Mode if your computer does not have hardware virtualization.  Here we’ll see how to import the XP Mode from Windows 7 Professional, Enterprise, or Ultimate into VirtualBox so you can run XP in it for free. Note: You need to have Windows 7 Professional or above to use XP Mode in this manner. In our tests we were able to get it to run on Home Premium as well, but you’ll be breaking Windows 7 licensing agreements. Getting Started First, download and install XP Mode (link below).  There is no need to download Virtual PC if your computer cannot run it, so just download the XP Mode from the link on the left. Install XP mode; just follow the default prompts as usual. Now, download and install VirtualBox 3.1.2 or higher(link below).  Install as normal, and simply follow the default prompts. VirtualBox may notify you that your network connection will be reset during the installation.  Press Yes to continue. During the install, you may see several popups asking you if you wish to install device drivers for USB and Network interfaces.  Simply click install, as these are needed for VirtualBox to run correctly. Setup only took a couple minutes, and doesn’t require a reboot. Setup XP Mode in VirtualBox: First we need to copy the default XP Mode so VirtualBox will not affect the original copy.  Browse to C:\Program Files\Windows XP Mode, and copy the file “Windows XP Mode base.vhd”.  Paste it in another folder of your choice, such as your Documents folder. Once you’ve copied the file, right-click on it and click Properties. Uncheck the “Read-only” box in this dialog, and then click Ok. Now, in VirtualBox, click New to create a new virtual machine. Enter the name of your virtual machine, and make sure the operating system selected is Windows XP. Choose how much memory you want to allow the virtual machine to use.  VirtualBox’ default is 192 Mb ram, but for better performance you can select 256 or 512Mb. Now, select the hard drive for the virtual machine.  Select “Use existing hard disk”, then click the folder button to choose the XP Mode virtual drive. In this window, click Add, and then browse to find the copy of XP Mode you previously made. Make sure the correct virtual drive is selected, then press Select. After selecting the VHD your screen should look like the following then click Next. Verify the settings you made are correct. If not, you can go back and make any changes. When everything looks correct click Finish. Setup XP Mode Now, in VirtualBox, click start to run XP Mode. The Windows XP in this virtual drive is not fully setup yet, so you will have to go through the setup process.   If you didn’t uncheck the “Read-only” box in the VHD properties before, you may see the following error.  If you see it, go back and check the file to makes sure it is not read-only. When you click in the virtual machine, it will capture your mouse by default.  Simply press the right Ctrl key to release your mouse so you can go back to using Windows 7.  This will only be the case during the setup process; after the Guest Additions are installed, the mouse will seamlessly move between operating systems. Now, accept the license agreement in XP.   Choose your correct locale and keyboard settings. Enter a name for your virtual XP, and an administrative password. Check the date, time, and time zone settings, and adjust them if they are incorrect.  The time and date are usually correct, but the time zone often has to be corrected. XP will now automatically finish setting up your virtual machine, and then will automatically reboot. After rebooting, select your automatic update settings. You may see a prompt to check for drivers; simply press cancel, as all the drivers we need will be installed later with the Guest Additions. Your last settings will be finalized, and finally you will see your XP desktop in VirtualBox. Please note that XP Mode may not remain activated after importing it into VirtualBox. When you activate it, use the key that is located at C:\Program Files\Windows XP Mode\key.txt.  Note: During our tests we weren’t able to get the activation to go through. We are looking into the issue and will have a revised article showing the correct way to get XP Mode in VirutalBox working correctly soon.    Now we have one final thing to install – the VirtualBox Guest Additions.  In the VirtualBox window, click “Devices” and then select “Install Guest Additions”. This should automatically launch in XP; if it doesn’t, click Start, then My Computer, and finally double-click on the CD drive which should say VirtualBox Guest Additions. Simply install with the normal presets. You can select to install an experimental 3D graphics driver if you wish to try to run games in XP in VirtualBox; however, do note that this is not fully supported and is currently a test feature. You may see a prompt informing you that the drivers have not passed Logo testing; simply press “Continue Anyway” to proceed with the installation.   When installation has completed, you will be required to reboot your virtual machine. Now, you can move your mouse directly from Windows XP to Windows 7 without pressing Ctrl. Integrating with Windows 7 Once your virtual machine is rebooted, you can integrate it with your Windows 7 desktop.  In the VirtualBox window, click Machine and then select “Seamless Mode”.   In Seamless mode you’ll have the XP Start menu and taskbar sit on top of your Windows 7 Start and Taskbar. Here we see XP running on Virtual Box in Seamless Mode. We have the old XP WordPad sitting next to the new Windows 7 version of WordPad. Another view of everything running seamlessly together on the same Windows 7 desktop. Hover the pointer over the XP taskbar to pull up the Virtual Box menu items. You can exit out of Seamless Mode from the VirtualBox menu or using “Ctrl+L”. Then you go back to having it run separately on your desktop again. Conclusion Running XP Mode in a Virtual Machine is a great way to experience the feature on computers without Hardware Virtualization capabilities. If you prefer VMware Player, then you’ll want to check out our articles on how to run XP Mode on Windows 7 machines without Hardware Virtualization, and how to create an XP Mode for Windows 7 Home Premium and Vista.
