    Hi, i have used rich:hotKey for h:inputText in my jsp page. And also i wrote jQuery for get the textBox value. When i use jquery, that time rich:kotKey not worked sample.jsp <%@page contentType="text/html" pageEncoding="UTF-8"%> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <%@ taglib uri="http://richfaces.org/a4j" prefix="a4j" %> <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <f:view> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>JSP Page</title> <script type="text/javascript" src="../../resource/js/jquery.min.js"/> <script type="text/javascript"> function typedName() { //Get The value using styleClass id var userName = jQuery.trim($('.textBox').val()); alert("Name is : " + userName); } // If i am not use above typedName() script and load src, then // the following testButton() clicked script perfectly worked. function testButton() { alert("Test Button Clicked"); } </script> </head> <body> <h:form> <rich:panel> <h:outputText value="Enter your Name : "/> <h:inputText id="textBox" styleClass="textBox" value ="" />&nbsp; <a4j:commandButton id="nameButton" value="NameButton" onclick="typedName();"/><br> <a4j:commandButton id="testButton" value="TestButton" onclick="testButton();" /> <%--HotKey for text Box and focus to testButton --%> <rich:hotKey key="return" selector="#textBox" handler="#{rich:element('testButton')}.click(); event.stopPropagation();event.preventDefault(); return false;"/> </rich:panel> </h:form> </body> </f:view> If i am not include the jquery, then that time i hit the enter button from text box, then automatically called testButton() script. If i include the Jquery, then rich:hotkey not work. I am also Used , var $J = jQuery.noConflict(); . But this time also not work jQuery. I hope help me about this. Thanks for your effort.

  • Flash Media Server Streaming: Content Protection

    - by dbemerlin
    Hi, i have to implement flash streaming for the relaunch of our video-on-demand system but either because i haven't worked with flash-related systems before or because i'm too stupid i cannot get the system to work as it has to. We need: Per file & user access control with checks on a WebService every minute if the lease time ran out mid-stream: cancelling the stream rtmp streaming dynamic bandwidth checking Video Playback with Flowplayer (existing license) I've got the streaming and bandwidth check working, i just can't seem to get the access control working. I have no idea how i know which file is played back or how i can play back a file depending on a key the user has entered. Server-Side Code (main.asc): application.onAppStart = function() { trace("Starting application"); this.payload = new Array(); for (var i=0; i < 1200; i++) { this.payload[i] = Math.random(); //16K approx } } application.onConnect = function( p_client, p_autoSenseBW ) { p_client.writeAccess = ""; trace("client at : " + p_client.uri); trace("client from : " + p_client.referrer); trace("client page: " + p_client.pageUrl); // try to get something from the query string: works var i = 0; for (i = 0; i < p_client.uri.length; ++i) { if (p_client.uri[i] == '?') { ++i; break; } } var loadVars = new LoadVars(); loadVars.decode(p_client.uri.substr(i)); trace(loadVars.toString()); trace(loadVars['foo']); // And accept the connection this.acceptConnection(p_client); trace("accepted!"); //this.rejectConnection(p_client); // A connection from Flash 8 & 9 FLV Playback component based client // requires the following code. if (p_autoSenseBW) { p_client.checkBandwidth(); } else { p_client.call("onBWDone"); } trace("Done connecting"); } application.onDisconnect = function(client) { trace("client disconnecting!"); } Client.prototype.getStreamLength = function(p_streamName) { trace("getStreamLength:" + p_streamName); return Stream.length(p_streamName); } Client.prototype.checkBandwidth = function() { application.calculateClientBw(this); } application.calculateClientBw = function(p_client) { /* lots of lines copied from an adobe sample, appear to work */ } Client-Side Code: <head> <script type="text/javascript" src="flowplayer-3.1.4.min.js"></script> </head> <body> <a class="rtmp" href="rtmp://xx.xx.xx.xx/vod_project/test_flv.flv" style="display: block; width: 520px; height: 330px" id="player"> </a> <script> $f( "player", "flowplayer-3.1.5.swf", { clip: { provider: 'rtmp', autoPlay: false, url: 'test_flv' }, plugins: { rtmp: { url: 'flowplayer.rtmp-3.1.3.swf', netConnectionUrl: 'rtmp://xx.xx.xx.xx/vod_project?foo=bar' } } } ); </script> </body> My first Idea was to get a key from the Query String, ask the web service about which file and user that key is for and play the file but i can't seem to find out how to play a file from server side. My second idea was to let flowplayer play a file, pass the key as query string and if the filename and key don't match then reject the connection but i can't seem to find out which file it's currently playing. The only remaining idea i have is: create a list of all files the user is allowed to open and set allowReadAccess or however it was called to allow those files, but that would be clumsy due to the current infrastructure. Any hints? Thanks.

  • How to make sql query dynamic?

    - by ClarkSKent
    Hello, I am using this pagination class and was looking for a way to make the sql query more dynamic instead of having it hardcoded. I have a 3 <li> elements that I want to be filter buttons, meaning when a user clicks on one of these elements I want It to send the id so I can use it in a sql query. So for the $sql = "select * from explore where category='marketing'"; (as seen below). When the user clicks on the 'automotive' button it will change the category above to automotive. Any help on this would be highly appreciated, Thanks. This is what my main page looks like: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_page.js"></script> <?php //Include the PS_Pagination class include('ps_pagination.php'); //Connect to mysql db $conn = mysql_connect('localhost', 'root', 'root'); mysql_select_db('ajax_demo',$conn); $sql = "select * from explore where category='marketing'"; //Create a PS_Pagination object $pager = new PS_Pagination($conn, $sql, 3, 11, 'param1=valu1&param2=value2'); //The paginate() function returns a mysql //result set for the current page $rs = $pager->paginate(); //Loop through the result set while($row = mysql_fetch_assoc($rs)) { echo "<table width='800px'>"; echo "<tr>"; echo"<td>"; echo $row['id']; echo"</td>"; echo"<td>"; echo $row['site_description']; echo"</td>"; echo"<td>"; echo $row['site_price']; echo"</td>"; echo "</tr>"; echo "</table>"; } echo "<ul id='pagination'>"; echo "<li>"; //Display the navigation echo $pager->renderFullNav(); echo "</li>"; echo "</ul>"; echo "<ul id='filter'>"; echo "<li id='marketing'>"; echo "Marketing"; echo "</li>"; echo "<li id='automotive'>"; echo "Automotive"; echo "</li>"; echo "<li id='sports'>"; echo "Sports"; echo "</li>"; echo "</ul>"; ?>

  • Blogger issue with custom background images on Chrome and Safari

    - by hdx
    This is weird, the site in question is blog.andrebatista.info and it is a hosted at blogger.com. I'm trying to make the blogger template look the same as the one in my main website, www.andrebatista.info. For some reason if I go directly to the blog address Chrome and Safari fail to display all of my background images... all of them. However if I first go to www.andrebatista.info first and then go to the blog it renders just fine ?¿ The way I'm customizing it is by adding a link to my main site's stylesheet at the very end of the head tag on the blogger template. That stylesheet is displayed below: *{ margin:0; padding:0; border:0; } html,body { background:#064169 url(http://www.andrebatista.info/images/main_gradient_slice.jpg) repeat-x; font-family: Arial, "MS Trebuchet", sans-serif; font-size:18px; } #main_wrapper{ margin: 0 auto; width:1024px; } #header{ background: url(http://www.andrebatista.info/images/header.jpg); height:133px; border:none; margin:0; } #menu_wrapper{ background: url(http://www.andrebatista.info/images/menu.jpg); height:34px; overflow:hidden; } #menu_wrapper .menu_item{ color:white; float: left; border: 1 px solid red; height: 34px; padding-top:10px; text-align:center; width:100px; } #menu_wrapper .first{ padding-left:240px; float:left; width:100px; } #menu_wrapper .active,#menu_wrapper .menu_item:hover{ background-color:white; color:Teal; cursor: pointer; } #content_area_wrapper{ background: url(http://www.andrebatista.info/images/body_bg_slice.jpg) repeat-y; } #content_area{ min-height:524px; background: url(http://www.andrebatista.info/images/main_content_top.jpg) repeat-x; } #main_banner{ background: url(http://www.andrebatista.info/images/main_banner.jpg) no-repeat center center; width:662px; height:338px; margin: 0 auto; } #main_banner div{ color:white; padding-left:47px; padding-right:164px; padding-top:105px; } #text_area{ overflow:hidden; width:662px; margin:0 auto; padding:14px; } #contentList{ padding:0 20px 20px 20px; } #text_area .left{ width:50%; float:left; } #text_area .left{ width:50%; float:right; } #footer2{ background: url(http://www.andrebatista.info/images/footer.jpg); height:62px; } #footer{ background: url(http://www.andrebatista.info/images/footer.jpg); height:62px; } Any ideas on what I could be missing?

  • mediaelement.js control sizes are wrong when clip nested in a hidden element

    - by Martin Francis
    It's a nasty one this. In an audio control placed within a container element whose display property is initially set to none, the audio clip does NOT correctly size the progress bar when it is initialised. This is clear when the container's display property is changed from 'none' to '' (which is equivalent to 'static'). But who would ever do that? I make extensive use of 'tabbed' display arrangements on community sites like this one: http://www.churchesInBracebridge.ca Owing to the page arrangement, the audio controls which you see under 'sermons' (which at the time of writing still using Flash rather than John's excellent library here) are initially rendered in a div that is hidden. Simplified Test case Rather than have anyone have to wade through all of that, here's a much simplified test case: http://jsfiddle.net/sJL6T/36 Here's the full page source for those who'd prefer to work with it that way. <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>MediaElementPlayer.js</title> <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="http://mediaelementjs.com/js/mejs-2.13.1/mediaelement-and-player.js"></script> <link rel="stylesheet" href="http://mediaelementjs.com/js/mejs-2.13.1/mediaelementplayer.css" /> <script type="text/javascript"> function toggle(id){ document.getElementById(id).style.display= (document.getElementById(id).style.display=='none' ? '' : 'none'); } </script> </head> <body> <h1>MediaElementPlayer.js</h1> <h2 onclick="return toggle('test1')">Initially Hidden (Click to toggle)</h2> <div id='test1' style='display:none'> <audio controls="controls"> <source src="http://mediaelementjs.com/media/AirReview-Landmarks-02-ChasingCorporate.mp3" type="audio/mp3" /> </audio> </div> <h2 onclick="return toggle('test2')">Initially Shown (Click to toggle)</h2> <div id='test2' style=''> <audio controls="controls"> <source src="http://mediaelementjs.com/media/AirReview-Landmarks-02-ChasingCorporate.mp3" type="audio/mp3" /> </audio> </div> <script> $('audio').mediaelementplayer(); </script> </body> </html> Possible Workarounds Now I know that Google maps has the same quirk and there are two possible ways I've used to deal with that: Use absolute positioning in a displayed div to place the element 10,000px to the left then bring it onto the stage when we want to see it Have the map pane displayed when loading then hide it as soon as it's loaded (ugly I know, but it usually works) However either approach would be a pain to do, as I have a lot of legacy code using the simpler div hiding method. I know that JQuery can get the dimensions of an element event if it is hidden - someone thoughtfully fiddled that and it does work: http://jsfiddle.net/sJL6T/9 Perhaps it may be possible to modify the actual library to find correct dimensions, even if the container itself is hidden? That would be wonderful, if it can be done! Initial experiments on mediaelement-and-player.js code I found that when I provided a fixed value in the setControlsSize function for railWidth, I got consistent results with both controls in the test case above (and obviously I'm working with my own copy of the library to do that, not the one stored at mediaelementjs.com): // outer area rail.width(railWidth); Change to this: // outer area railWidth=216; rail.width(railWidth); Many thanks in anticipation!

  • Random Complete System Unresponsiveness Running Mathematical Functions

    - by Computer Guru
    I have a program that loads a file (anywhere from 10MB to 5GB) a chunk at a time (ReadFile), and for each chunk performs a set of mathematical operations (basically calculates the hash). After calculating the hash, it stores info about the chunk in an STL map (basically <chunkID, hash>) and then writes the chunk itself to another file (WriteFile). That's all it does. This program will cause certain PCs to choke and die. The mouse begins to stutter, the task manager takes 2 min to show, ctrl+alt+del is unresponsive, running programs are slow.... the works. I've done literally everything I can think of to optimize the program, and have triple-checked all objects. What I've done: Tried different (less intensive) hashing algorithms. Switched all allocations to nedmalloc instead of the default new operator Switched from stl::map to unordered_set, found the performance to still be abysmal, so I switched again to Google's dense_hash_map. Converted all objects to store pointers to objects instead of the objects themselves. Caching all Read and Write operations. Instead of reading a 16k chunk of the file and performing the math on it, I read 4MB into a buffer and read 16k chunks from there instead. Same for all write operations - they are coalesced into 4MB blocks before being written to disk. Run extensive profiling with Visual Studio 2010, AMD Code Analyst, and perfmon. Set the thread priority to THREAD_MODE_BACKGROUND_BEGIN Set the thread priority to THREAD_PRIORITY_IDLE Added a Sleep(100) call after every loop. Even after all this, the application still results in a system-wide hang on certain machines under certain circumstances. Perfmon and Process Explorer show minimal CPU usage (with the sleep), no constant reads/writes from disk, few hard pagefaults (and only ~30k pagefaults in the lifetime of the application on a 5GB input file), little virtual memory (never more than 150MB), no leaked handles, no memory leaks. The machines I've tested it on run Windows XP - Windows 7, x86 and x64 versions included. None have less than 2GB RAM, though the problem is always exacerbated under lower memory conditions. I'm at a loss as to what to do next. I don't know what's causing it - I'm torn between CPU or Memory as the culprit. CPU because without the sleep and under different thread priorities the system performances changes noticeably. Memory because there's a huge difference in how often the issue occurs when using unordered_set vs Google's dense_hash_map. What's really weird? Obviously, the NT kernel design is supposed to prevent this sort of behavior from ever occurring (a user-mode application driving the system to this sort of extreme poor performance!?)..... but when I compile the code and run it on OS X or Linux (it's fairly standard C++ throughout) it performs excellently even on poor machines with little RAM and weaker CPUs. What am I supposed to do next? How do I know what the hell it is that Windows is doing behind the scenes that's killing system performance, when all the indicators are that the application itself isn't doing anything extreme? Any advice would be most welcome.

  • SQL Server 2008: Using Multiple dts Ranges to Build a Set of Dates

    - by raoulcousins
    I'm trying to build a query for a medical database that counts the number of patients that were on at least one medication from a class of medications (the medications listed below in the FAST_MEDS CTE) and had either: 1) A diagnosis of myopathy (the list of diagnoses in the FAST_DX CTE) 2) A CPK lab value above 1000 (the lab value in the FAST_LABS CTE) and this diagnosis or lab happened AFTER a patient was on a statin. The query I've included below does that under the assumption that once a patient is on a statin, they're on a statin forever. The first CTE collects the ids of patients that were on a statin along with the first date of their diagnosis, the second those with a diagnosis, and the third those with a high lab value. After this I count those that match the above criteria. What I would like to do is drop the assumption that once a patient is on a statin, they're on it for life. The table edw_dm.patient_medications has a column called start_dts and end_dts. This table has one row for each prescription written, with start_dts and end_dts denoting the start and end date of the prescription. End_dts could be null, which I'll take to assume that the patient is currently on this medication (it could be a missing record, but I can't do anything about this). If a patient is on two different statins, the start and ends dates can overlap, and there may be multiple records of the same medication for a patient, as in a record showing 3-11-2000 to 4-5-2003 and another for the same patient showing 5-6-2007 to 7-8-2009. I would like to use these two columns to build a query where I'm only counting the patients that had a lab value or diagnosis done during a time when they were already on a statin, or in the first n (say 3) months after they stopped taking a statin. I'm really not sure how to go about rewriting the first CTE to get this information and how to do the comparison after the CTEs are built. I know this is a vague question, but I'm really stumped. Any ideas? As always, thank you in advance. Here's the current query: WITH FAST_MEDS AS ( select distinct statins.mrd_pt_id, min(year(statins.order_dts)) as statin_yr from edw_dm.patient_medications as statins inner join mrd.medications as mrd on statins.mrd_med_id = mrd.mrd_med_id WHERE mrd.generic_nm in ( 'Lovastatin (9664708500)', 'lovastatin-niacin', 'Lovastatin/Niacin', 'Lovastatin', 'Simvastatin (9678583966)', 'ezetimibe-simvastatin', 'niacin-simvastatin', 'ezetimibe/Simvastatin', 'Niacin/Simvastatin', 'Simvastatin', 'Aspirin Buffered-Pravastatin', 'aspirin-pravastatin', 'Aspirin/Pravastatin', 'Pravastatin', 'amlodipine-atorvastatin', 'Amlodipine/atorvastatin', 'atorvastatin', 'fluvastatin', 'rosuvastatin' ) and YEAR(statins.order_dts) IS NOT NULL and statins.mrd_pt_id IS NOT NULL group by statins.mrd_pt_id ) select * into #meds from FAST_MEDS ; --return patients who had a diagnosis in the list and the year that --diagnosis was given with FAST_DX AS ( SELECT pd.mrd_pt_id, YEAR(pd.init_noted_dts) as init_yr FROM edw_dm.patient_diagnoses as pd inner join mrd.diagnoses as mrd on pd.mrd_dx_id = mrd.mrd_dx_id and mrd.icd9_cd in ('728.89','729.1','710.4','728.3','729.0','728.81','781.0','791.3') ) select * into #dx from FAST_DX; --return patients who had a high cpk value along with the year the cpk --value was taken with FAST_LABS AS ( SELECT pl.mrd_pt_id, YEAR(pl.order_dts) as lab_yr FROM edw_dm.patient_labs as pl inner join mrd.labs as mrd on pl.mrd_lab_id = mrd.mrd_lab_id and mrd.lab_nm = 'CK (CPK)' WHERE pl.lab_val between 1000 AND 999998 ) select * into #labs from FAST_LABS; -- count the number of patients who had a lab value or a medication -- value taken sometime AFTER their initial statin diagnosis select count(distinct p.mrd_pt_id) as ct from mrd.patient_demographics as p join #meds as m on p.mrd_pt_id = m.mrd_pt_id AND ( EXISTS ( SELECT 'A' FROM #labs l WHERE p.mrd_pt_id = l.mrd_pt_id and l.lab_yr >= m.statin_yr ) OR EXISTS( SELECT 'A' FROM #dx d WHERE p.mrd_pt_id = d.mrd_pt_id AND d.init_yr >= m.statin_yr ) )

  • Break a class in twain, or impose an interface for restricted access?

    - by bedwyr
    What's the best way of partitioning a class when its functionality needs to be externally accessed in different ways by different classes? Hopefully the following example will make the question clear :) I have a Java class which accesses a single location in a directory allowing external classes to perform read/write operations to it. Read operations return usage stats on the directory (e.g. available disk space, number of writes, etc.); write operations, obviously, allow external classes to write data to the disk. These methods always work on the same location, and receive their configuration (e.g. which directory to use, min disk space, etc.) from an external source (passed to the constructor). This class looks something like this: public class DiskHandler { public DiskHandler(String dir, int minSpace) { ... } public void writeToDisk(String contents, String filename) { int space = getAvailableSpace(); ... } public void getAvailableSpace() { ... } } There's quite a bit more going on, but this will do to suffice. This class needs to be accessed differently by two external classes. One class needs access to the read operations; the other needs access to both read and write operations. public class DiskWriter { DiskHandler diskHandler; public DiskWriter() { diskHandler = new DiskHandler(...); } public void doSomething() { diskHandler.writeToDisk(...); } } public class DiskReader { DiskHandler diskHandler; public DiskReader() { diskHandler = new DiskHandler(...); } public void doSomething() { int space = diskHandler.getAvailableSpace(...); } } At this point, both classes share the same class, but the class which should only read has access to the write methods. Solution 1 I could break this class into two. One class would handle read operations, and the other would handle writes: // NEW "UTILITY" CLASSES public class WriterUtil { private ReaderUtil diskReader; public WriterUtil(String dir, int minSpace) { ... diskReader = new ReaderUtil(dir, minSpace); } public void writeToDisk(String contents, String filename) { int = diskReader.getAvailableSpace(); ... } } public class ReaderUtil { public ReaderUtil(String dir, int minSpace) { ... } public void getAvailableSpace() { ... } } // MODIFIED EXTERNALLY-ACCESSING CLASSES public class DiskWriter { WriterUtil diskWriter; public DiskWriter() { diskWriter = new WriterUtil(...); } public void doSomething() { diskWriter.writeToDisk(...); } } public class DiskReader { ReaderUtil diskReader; public DiskReader() { diskReader = new ReaderUtil(...); } public void doSomething() { int space = diskReader.getAvailableSpace(...); } } This solution prevents classes from having access to methods they should not, but it also breaks encapsulation. The original DiskHandler class was completely self-contained and only needed config parameters via a single constructor. By breaking apart the functionality into read/write classes, they both are concerned with the directory and both need to be instantiated with their respective values. In essence, I don't really care to duplicate the concerns. Solution 2 I could implement an interface which only provisions read operations, and use this when a class only needs access to those methods. The interface might look something like this: public interface Readable { int getAvailableSpace(); } The Reader class would instantiate the object like this: Readable diskReader; public DiskReader() { diskReader = new DiskHandler(...); } This solution seems brittle, and prone to confusion in the future. It doesn't guarantee developers will use the correct interface in the future. Any changes to the implementation of the DiskHandler could also need to update the interface as well as the accessing classes. I like it better than the previous solution, but not by much. Frankly, neither of these solutions seems perfect, but I'm not sure if one should be preferred over the other. I really don't want to break the original class up, but I also don't know if the interface buys me much in the long run. Are there other solutions I'm missing?

  • Unable to show Desktop Notifications using Google Chrome

    - by Praveen Kumar
    I followed the instructions as given in Using The Notifications API. Also I faced many problems like the below, because I added the document.querySelector() inside the <head> part: Uncaught TypeError: Cannot call method 'addEventListener' of null Now I have the below source, where I am able to Check Notification Support, and Check Notification Permissions links. Guide me how to bring in notifications in a simpler way. Also, I tried this: $("#html").click(function() { if (window.webkitNotifications.checkPermission() == 0) { createNotificationInstance({ notificationType: 'html' }); } else { window.webkitNotifications.requestPermission(); } }); Now I am stuck with this source. I need to generate HTML & Simple Notifications. Am I missing something? Please guide me.

  • html button elemenents and onserverclick attribute in asp.net

    - by Adrian Adkison
    I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results. client side: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <script type="text/javascript" src="/scripts/jquery-1.4.min.js"></script> </head> <body> <form id="form1" runat="server"> <asp:Label ID="_response" runat="server"></asp:Label> <input id="input1" type="text" /> <input id="input2" type="text" /> <button id="first" type="button" class="defaultBtn" runat="server" onserverclick="ServerMethod1">test1</button> <button id="second" type="button" runat="server" onserverclick="ServerMethod2">test2</button> </form> <script type="text/javascript"> jQuery('form input').keyup( function(e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { $('button.defaultBtn').click(); return true; } } ); </script> </body> </html> server side: public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ServerMethod1(object sender, EventArgs e) { _response.Text = "server method1 was hit"; } protected void ServerMethod2(object sender, EventArgs e) { _response.Text = "server method2 was hit"; } } What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Does anyone know what is going on? Thanks p.s. Chrome worked as expected

  • Join and sum not compatible matrices through data.table

    - by leodido
    My goal is to "sum" two not compatible matrices (matrices with different dimensions) using (and preserving) row and column names. I've figured this approach: convert the matrices to data.table objects, join them and then sum columns vectors. An example: > M1 1 3 4 5 7 8 1 0 0 1 0 0 0 3 0 0 0 0 0 0 4 1 0 0 0 0 0 5 0 0 0 0 0 0 7 0 0 0 0 1 0 8 0 0 0 0 0 0 > M2 1 3 4 5 8 1 0 0 1 0 0 3 0 0 0 0 0 4 1 0 0 0 0 5 0 0 0 0 0 8 0 0 0 0 0 > M1 %ms% M2 1 3 4 5 7 8 1 0 0 2 0 0 0 3 0 0 0 0 0 0 4 2 0 0 0 0 0 5 0 0 0 0 0 0 7 0 0 0 0 1 0 8 0 0 0 0 0 0 This is my code: M1 <- matrix(c(0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0), byrow = TRUE, ncol = 6) colnames(M1) <- c(1,3,4,5,7,8) M2 <- matrix(c(0,0,1,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0), byrow = TRUE, ncol = 5) colnames(M2) <- c(1,3,4,5,8) # to data.table objects DT1 <- data.table(M1, keep.rownames = TRUE, key = "rn") DT2 <- data.table(M2, keep.rownames = TRUE, key = "rn") # join and sum of common columns if (nrow(DT1) > nrow(DT2)) { A <- DT2[DT1, roll = TRUE] A[, list(X1 = X1 + X1.1, X3 = X3 + X3.1, X4 = X4 + X4.1, X5 = X5 + X5.1, X7, X8 = X8 + X8.1), by = rn] } That outputs: rn X1 X3 X4 X5 X7 X8 1: 1 0 0 2 0 0 0 2: 3 0 0 0 0 0 0 3: 4 2 0 0 0 0 0 4: 5 0 0 0 0 0 0 5: 7 0 0 0 0 1 0 6: 8 0 0 0 0 0 0 Then I can convert back this data.table to a matrix and fix row and column names. The questions are: how to generalize this procedure? I need a way to automatically create list(X1 = X1 + X1.1, X3 = X3 + X3.1, X4 = X4 + X4.1, X5 = X5 + X5.1, X7, X8 = X8 + X8.1) because i want to apply this function to matrices which dimensions (and row/columns names) are not known in advance. In summary I need a merge procedure that behaves as described. there are other strategies/implementations that achieve the same goal that are, at the same time, faster and generalized? (hoping that some data.table monster help me) to what kind of join (inner, outer, etc. etc.) is assimilable this procedure? Thanks in advance. p.s.: I'm using data.table version 1.8.2 EDIT - SOLUTIONS @Aaron solution. No external libraries, only base R. It works also on list of matrices. add_matrices_1 <- function(...) { a <- list(...) cols <- sort(unique(unlist(lapply(a, colnames)))) rows <- sort(unique(unlist(lapply(a, rownames)))) out <- array(0, dim = c(length(rows), length(cols)), dimnames = list(rows,cols)) for (m in a) out[rownames(m), colnames(m)] <- out[rownames(m), colnames(m)] + m out } @MadScone solution. Used reshape2 package. It works only on two matrices per call. add_matrices_2 <- function(m1, m2) { m <- acast(rbind(melt(M1), melt(M2)), Var1~Var2, fun.aggregate = sum) mn <- unique(colnames(m1), colnames(m2)) rownames(m) <- mn colnames(m) <- mn m } BENCHMARK (100 runs with microbenchmark package) Unit: microseconds expr min lq median uq max 1 add_matrices_1 196.009 257.5865 282.027 291.2735 549.397 2 add_matrices_2 13737.851 14697.9790 14864.778 16285.7650 25567.448 No need to comment the benchmark: @Aaron solution wins. I'll continue to investigate a similar solution for data.table objects. I'll add other solutions eventually reported or discovered.

  • using getScript to import plugin on page using multiple versions of jQuery

    - by mikez302
    I am developing an app on a page that uses jQuery 1.2.6, but I would like to use jQuery 1.4.2 for my app. I really don't like to use multiple versions of jQuery like this but the copy on the page (1.2.6) is something I have no control over. I decided to isolate my code like this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <script type="text/javascript" src="jquery-1.2.6.min.js> <script type="text/javascript" src="pageStuff.js"> </head> <body> Welcome to our page. <div id="app"> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript" src="myStuff.js"> </div> </body></html> The file myStuff.js has my own code that is supposed to use jQuery 1.4.2, and it looks like this: (function($) { //wrap everything in function to add ability to use $ var with noConflict var jQuery = $; //my code })(jQuery.noConflict(true)); This is an extremely simplified version, but I hope you get the idea of what I did. For a while, everything worked fine. However, I decided to want to use a jQuery plugin in a separate file. I tested it and it acted funny. After some experimentation, I found out that the plugin was using the old version of jQuery, when I wanted it to use the new version. Does anyone know how to import and run a js file from the context within the function wrapping the code in myStuff.js? In case this matters to anyone, here is how I know the plugin is using the old version, and what I did to try to solve the problem: I made a file called test.js, consisting of this line: alert($.fn.jquery); I tried referencing the file in a script tag the way external Javascript is usually included, below myStuff.js, and it came up as 1.2.6, like I expected. I then got rid of that script tag and put this line in myStuff.js: $.getScript("test.js"); and it still came back as 1.2.6. That wasn't a big surprise -- according to jQuery's documentation, scripts included that way are executed in the global context. I then tried doing this instead: var testFn = $.proxy($.getScript, this); testFn("test.js"); and it still came back as 1.2.6. After some tinkering, I found out that the "this" keyword referred to the window, which I assume means the global context. I am looking for something to put in place of "this" to refer to the context of the enclosing function, or some other way to make the code in the file run from the enclosing function. I noticed that if I copy and paste the code, it works fine, but it is a big plugin that is used in many places, and I would prefer not to clutter up my file with their code. I am out of ideas. Does anyone else know how to do this?

  • jQuery gallery scrolling effect with ease

    - by Sebastian Otarola
    So, I got this page from a friend and I think the gallery is amazingly done. Too bad it's in Flash ; http://selected.com/en/#/collection/homme/ Now, I'm trying to replicate the effect with jQuery. I've made all the loco searches on google one could think of. Zooming the picture is not a problem, the problem lies within the scrolling, how they come together at the ease part. I'm looking for solution in how to make the thumbnail animate when you scroll the page, they drag behind and infront of each other in a very subtle way - I've got (With a lot of help from Whirl3d in the jQuery-irc channel) this for the scrollup/down part of the mouse but the scrolling goes haywire; I Thought I post it here where I've come many times to get answers to a lot of questions and code-errors.

  • 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.

  • Drupal's not reading correct values from DB

    - by John
    Hey Everyone, Here is my current problem. I am working with the chat module and I'm building a module that notifies users via AJAX that they have been invited to a chat. The current table structure for the invites table looks like this: |-------------------------------------------------------------------------| | CCID | NID | INVITER_UID | INVITEE_UID | NOTIFIED | ACCEPTED | |-------------------------------------------------------------------------| | int | int | int | int | (0 or 1) | (0 or 1) | |-------------------------------------------------------------------------| I'm using the periodical updater plug-in for JQuery to continually poll the server to check for invites. When an invite is found, I set the notified from 0 to 1. However, my problem is the periodical updater. When I first see that there is an invite, I notify the user, and set notified to 1. On the next select though, I get the same results before, as if the update didn't work. But, when I got check the database, I can see that it worked just fine. It's as if the query is querying a cache, but I can't figure it out. My code for the periodical updater is as follows: window.onload = function() { var uid = $('a#chat_uid').html(); $.PeriodicalUpdater( '/steelylib/sites/all/modules/_chat_whos_online/ajax/ajax.php', //url to service { method: 'get', //send data via... data: {uid: uid}, //data to send minTimeout: '1000', //min time before server is polled (milli-sec.) maxTimeout: '20000', //max time before server is polled (milli-sec.) multiplyer: '1.5', //multiply against curretn poll time every time constant data is returned type: 'text', //type of data recieved (response type) maxCalls: 0, //max calls to make (0=unlimited) autoStop: 0 //max calls with constant data (0=unlimited/disabled) }, function(data) //callback function { alert( data ); //for now, until i get it working } ); } And my code for the ajax call is as follows: <?php #bootstrap Drupal, and call function, passing current user's uid. function _create_chat_node_check_invites($uid) { cache_clear_all('chatroom_chat_list', 'cache'); $query = "SELECT * FROM {chatroom_chat_invite} WHERE notified=0 AND invitee_uid=%d and accepted=0"; $query_results = db_query( $query, $uid ); $json = '{"invites":['; while( $row = db_fetch_object($query_results) ) { var_dump($row); global $base_url; $url = $base_url . '/content/privatechat' . $uid .'-' . $row->inviter_uid; $inviter = db_fetch_object( db_query( "SELECT name FROM {users} WHERE uid = %d", $row->inviter_uid ) ); $invitee = db_fetch_object( db_query( "SELECT name FROM {users} WHERE uid = %d", $row->invitee_uid ) ); #reset table $query = "UPDATE {chatroom_chat_invite} " ."SET notified=1 " ."WHERE inviter_uid=%d AND invitee_uid=%d"; db_query( $query, $row->inviter_uid, $row->invitee_uid ); $json .= '['; $json .= '"' . $url .

  • Geolocation through Android's GPS Provider on a website?

    - by Corey Ogburn
    I'm trying to get the geolocation of the mobile device in a regular website, not a webview of an application or anything native like that. I'm getting a location, but it's highly inaccurate, the accuracy comes back as 3230 or some other outrageous number. I'm assuming that's in meters, either way it's not nearly accurate enough. By comparison, the same webpage on a laptop gets an accuracy of 30-40. My first thought was that it was using the Network Provider instead of the GPS Provider, telling me where I am based on tower location and reach. A little research later I found enableHighAccuracy and set it true in the options that I pass. After including that, I still notice no difference. Here's the test page's HTML/javascript: <html> <head> <script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script> <script type="text/javascript"> function OnLoad() { $("#Status").text("Init"); if (navigator.geolocation) { $("#Status").text("Supports Geolocation"); navigator.geolocation.getCurrentPosition(HandleLocation, LocationError, { enableHighAccuracy: true }); $("#Status").text("Sent position request..."); } else { $("#Status").text("Doesn't support geolocation"); } } function HandleLocation(position) { $("#Status").text("Received response:"); $("#Position").text("(" + position.coords.latitude + ", " + position.coords.longitude + ") accuracy: " + position.coords.accuracy); var loc = new Microsoft.Maps.Location(position.coords.latitude, position.coords.longitude); GetMap(loc); } function LocationError(error) { switch(error.code) { case error.PERMISSION_DENIED: alert("Location not provided"); break; case error.POSITION_UNAVAILABLE: alert("Current location not available"); break; case error.TIMEOUT: alert("Timeout"); break; default: alert("unknown error"); break; } } function GetMap(loc) { var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), {credentials: "Aj59meaCR1e7rNgkfQy7j08Pd3mzfP1r04hGesGmLe2a3ZwZ3iGecwPX2SNPWq5a", center: loc, mapTypeId: Microsoft.Maps.MapTypeId.road, zoom: 15}); } </script> </head> <body onload="javascript:OnLoad()"> <div id="Status"></div> <div id="Position"></div><br/> <div id='mapDiv' style="position:relative; width:600px; height:400px;"></div> </body> </html> I'm testing this on a rooted MyTouch 3G running Cyanogen 6.1 stable, Android 2.2 and GPS is enabled. In case rooting was a problem, I have also had various friends and coworkers try the webpage on their non-rooted 2.0+ Android devices. Each phone had various effects on the accuracy, but none were better than 1000, I attribute this to the different carriers. I have not (but eventually will) tested with iPhone or other location-aware cell phones.

  • swap a div to an embed form when user tweets using the @anywhere function box

    - by Jeff
    I'm using the @anywhere twitter function on the front page of my site (vocabbomb.com) and right now it works great to allow users to tweet straight away. Problem is, when they click tweet, it just reloads the twitter box, empty. I want it to load something new, like a "thank you, now fill in this email form" and show a mailchimp form. Ok so this is the @anywhere code currently working fine: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", }); }); </script> So this is fine, and when the user writes a tweet, it just re-displays the twitter box. I understand there is a function that lets you specify stuff after the tweet is made: (example from http://dev.twitter.com/pages/anywhere_tweetbox) <div id="example-ontweet"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#example-ontweet").tweetBox({ onTweet : function(plaintext, html) { console.log(plaintext); alert(html); } }); }); </script> Is this the best way to attempt this? Or do I need a function or something that changes what's in the div to something else? I want the mailchimp email form to show up after the tweet. It includes a ton of script and tags and starts like this: <!-- Begin MailChimp Signup Form --> <!--[if IE]> <style type="text/css" media="screen"> #mc_embed_signup fieldset {position: relative;} #mc_embed_signup legend {position: absolute; top: -1em; left: .2em;} </style> <![endif]--> <!--[if IE 7]> <style type="text/css" media="screen"> .mc-field-group {overflow:visible;} </style> <![endif]--> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.validate.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.form.js"></script> <div id="mc_embed_signup"> <form action="http://faresharenyc.us1.list-manage.com/subscribe/post?u=106b58b4751a007d826715754&amp;id=2fe6ba4e6a" method="post" id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate" target="_blank" style="font: normal 100% Arial, sans-serif;font-size: 10px;"> ... So my attempt to just require it inside the function didn't work at all: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", onTweet: function(plain, html){ <?php require_once('mailchimp.html'); ?> } }); }); </script> Nettuts had a brief discussion here: http://net.tutsplus.com/tutorials/javascript-ajax/using-twitters-anywhere-service-in-6-steps/ I am seeing now that the 'onTweet' function simply adds some text above the twitter box, but doesn't actually replace the entire twitter box. How do I do that? Is it possible? Thanks!

  • Redis Cookbook Chat Recipe

    I am a new starter to Node.Js and Redis. I got the Redis cookbook and was trying out the Chat client & Server recipe.

  • Element.appendChild() hosed in IE .. workaround? (related to innerText vs textContent)

    - by Rowe Morehouse
    I've heard that using el.innerText||el.textContent can yield unreliable cross-browswer results, so I'm walking the DOM tree to collect text nodes recursively, and write them into tags in the HTML body. What this script does is read hash substring valus from the window.location and write them into the HTML. This script is working for me in Chrome & Firefox, but choking in IE. I call the page with an URL syntax like this: http://example.com/pagename.html#dyntext=FOO&dynterm=BAR&dynimage=FRED UPDATE UPDATE UPDATE Solution: I moved the scripts to before </body> (where they should have been) then removed console.log(sPageURL); and now it's working in Chrome, Firefox, IE8 and IE9. This my workaround for the innerText vs textContent crossbrowser issue when you are just placing text rather than getting text. In this case, getting hash substring values from the window.location and writing them into the page. <html> <body> <span id="dyntext-span" style="font-weight: bold;"></span><br /> <span id="dynterm-span" style="font-style: italic;"></span><br /> <span id="dynimage-span" style="text-decoration: underline;"></span><br /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script> <script> $(document).ready(function() { var tags = ["dyntext", "dynterm", "dynimage"]; for (var i = 0; i < tags.length; ++i) { var param = GetURLParameter(tags[i]); if (param) { var dyntext = GetURLParameter('dyntext'); var dynterm = GetURLParameter('dynterm'); var dynimage = GetURLParameter('dynimage'); } } var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage); elem.appendChild(text); }); function GetURLParameter(sParam) { var sPageURL = window.location.hash.substring(1); var sURLVariables = sPageURL.split('&'); for (var i = 0; i < sURLVariables.length; i++) { var sParameterName = sURLVariables[i].split('='); if (sParameterName[0] == sParam) { return sParameterName[1]; } } } </script> </body> </html> FINAL UPDATE If your hash substring values require spaces (like a linguistic phrase with three words, for example) then separate the words with the + character in your URI, and replace the unicode \u002B character with a space when you create each text node, like this: var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage.replace(/\u002B/g, " ")); elem.appendChild(text); Now form your URI like this: http://example.com/pagename.html#dyntext=FOO+MAN+CHU&dynterm=BAR+HOPPING&dynimage=FRED+IS+DEAD
