  • Stop scrolling to ID when opening jQuery Modal via URL

    - by markedup
    I need to be able to open an ID'd jQuery UI Modal on a page when that modal's ID is passed in the page's URL. For example: http://mysite.com/visit.html#directions #directions is an ID'd DIV at the very bottom of the page, right before the closing BODY element. It's instantiated as a jQuery UI dialog on page load, then I'm running a function to check the current URL for the modal's ID. If the URL contains the modal's ID, the modal is opened. Here's what my auto-open function looks like: function autoOpenModal() { if ( document.location.href.indexOf('#') ) { var uriParts = document.location.href.split('#'); var hashID = '#' + uriParts[1]; if ( $(hashID) && $(hashID).hasClass('dialog')) { $(hashID).dialog('open'); } } } The problem I'm having is that the browser is automatically scrolling down to the ID at the very bottom of the page before the modal is opened. So when the user closes the modal they're at the bottom of the page (which seems "broken" to me). Can anyone tell me how I stop the browser from auto-scrolling down to the ID please? I've had a look at event.preventDefault() but without success; I'm not sure where or how to use it in the event chain.

  • Which pdf elements could cause crashes?

    - by Felixyz
    This is a very general question but it's based on a specific problem. I've created a pdf reader app for the iPad and it works fine except for certain pdf pages which always crash the app. We now found out that the very same pages cause Safari to crash as well, so as I had started to suspect the problem is somewhere in Apple's pdf rendering code. From what I have been able to see, the crashing pages cause the rendering libraries to start allocating memory like mad until the app is killed. I have nothing else to help me pinpoint what triggers this process. It doesn't necessarily happen with the largest documents, or the ones with the most shapes. In fact, we haven't found any parameter that helps us predict which pages will crash and which not. Now we just discovered that running the pages through a consumer program that lets you merge docs gets rid of the problem, but I haven't been able to detect which attribute or element it is that is the key. Changing documents by hand is also not an option for us in the long run. We need to run an automated process on our server. I'm hoping someone with deeper knowledge about the pdf file format would be able to point me in a reasonable direction to look for document features that could cause this kind of behavior. All I've found so far is something about JBIG2 images, and I don't think we have any of those.

  • How to add jsf components in javascript?

    - by Guru
    Is it possible to add JSF Components using javascript? In my case , on change of a select option , i need to display a different combination of input controls (like text box(s)). I thought i could use a element and innerHTML property to display the dynamic controls.But it seems to not work!!! <h:selectOneMenu id="browseType" class="TextBlackNormal" value="#{adminBean.browseType}" onchange="showDynamicBox(this);" valueChangeListener="#{adminBean.theValueChanged}"> <f:selectItems value="#{adminBean.browseTypeList}" /> </h:selectOneMenu> &#160;&#160;&#160;</td> <td> <div id="dynamicBox" style="display:block"><h:inputText class="TextBlackNormal" size="32" name="browseValue" id="browseValue" value="#{adminBean.browseValue}" /></div> </td> javascript code : ~~~~~~~~~~~~~~~~ function showDynamicBox(selectObjj) { //alert('showDynamicBox ' +showDynamicBox); if(selectObjj.options[selectObjj.selectedIndex].value=='IBD/Office/IP' || selectObjj.options[selectObjj.selectedIndex].value=='APA#' ) { alert('just about to change'); document.getElementById("dynamicBox").innerHTML='<h:inputText class="TextBlackNormal" size="3" name="val1" id="val1" /> <h:inputText class="TextBlackNormal" size="3" name="val2" id="val2" /> <h:inputText class="TextBlackNormal" size="3" name="val3" id="val3" /> '; alert(' --> ' +document.getElementById("dynamicBox").innerHTML); }else{ alert('back to pavillion'); document.getElementById("dynamicBox").innerHTML='<h:inputText class="TextBlackNormal" size="32" name="browseValue" id="browseValue" value="#{adminBean.browseValue}" />'; } }

  • WPF ToolBar Separator shrinks to nothing when inside a StackPanel

    - by qntmfred
    Given the very simple wpf app <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="800"> <Grid> <ToolBar Height="50" > <MenuItem Header="Test1" /> <MenuItem Header="Test2" /> <StackPanel Orientation="Horizontal"> <Separator /> <MenuItem Header="Test3" /> <MenuItem Header="Test4" /> <MenuItem Header="Test5" /> </StackPanel> </ToolBar> </Grid> </Window> The Separator element shrinks to nothing. If I put the Separator just before the StackPanel begins, it will show up. Why does this happen? Is there a style setting that can be applied somewhere to avoid this?

  • prevent schemagen from adding the super-class to the schema?

    - by shay
    Hi, how do i prevent schemagen from adding the super-class to the schema? I have tried using XMLTransient on the super-class, and on its fields but they still show up in the schema . for example : @XmlTransient public class Asset { @XmlTransient public Long ID; } public class Movie extends Asset { } creates this schema : <xs:complexType name="asset"> <xs:sequence> <xs:element name="ID" type="xs:long" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="movie"> <xs:complexContent> <xs:extension base="asset"> <xs:sequence/> </xs:extension> </xs:complexContent> </xs:complexType> the schema that i would like to see is : <xs:complexType name="movie"> <xs:complexContent> <xs:sequence/> </xs:extension> </xs:complexContent> </xs:complexType>

  • Jquery .wrap and first-child

    - by Johann
    Hi, I'm in a situation in which I need to use .wrap and :first-child. This is what I am doing: <script>$("a").wrap("<div class='category-wrapper'></div>");</script> <script>$("div.category-wrapper:first-child").addClass("first");</script> This should render a div.category-wrapper outside a link and then add a "first" class to every first div.category-wrapper. The output is: <div class="category-wrapper"><a href="#">Test</a></div> Which is good! However, I am not able to get the "first-child" to work (it doesn't adds the "first" class). If I use it somewhere else it works so I am sure it's something related to the dynamic rendering of the previous element. Any help is appreciated! Thanks! Sample output would be: <div class="category-wrapper"><a href="#">Test #1</a></div> <div class="category-wrapper"><a href="#">Test #2</a></div> <div class="category-wrapper"><a href="#">Test #3</a></div> <div class="category-wrapper"><a href="#">Test #4</a></div> Desired output: <div class="category-wrapper first"><a href="#">Test #1</a></div> <div class="category-wrapper"><a href="#">Test #2</a></div> <div class="category-wrapper"><a href="#">Test #3</a></div> <div class="category-wrapper"><a href="#">Test #4</a></div> However, I am not able to make it work.

  • Implementing a c/c++ style union as a column in MySQL

    - by user81338
    Friends, I have a strange need and cannot think my way through the problem. The great and mighty Google is of little help due to keyword recycling (as you'll see). Can you help? What I want to do is store data of multiple types in a single column in MySQL. This is the database equivalent to a C union (and if you search for MySQL and Union, you obviously get a whole bunch of stuff on the UNION keyword in SQL). [Contrived and simplified case follows] So, let us say that we have people - who have names - and STORMTROOPERS - who have TK numbers. You cannot have BOTH a NAME and a TK number. You're either BOB SMITH -or- TK409. In C I could express this as a union, like so: union { char * name; int tkNo; } EmperialPersonnelRecord; This makes it so that I am either storing a pointer to a char array or an ID in the type EmperialPersonnelRecord, but not both. I am looking for a MySQL equivalent on a column. My column would store either an int, double, or varchar(255) (or whatever combination). But would only take up the space of the largest element. Is this possible? (of course anything is possible given enough time, money and will - I mean is it possible if I am poor, lazy and on a deadline... aka "out of the box")

  • Database localization

    - by Don
    Hi, I have a number of database tables that contain name and description columns which need to be localized. My initial attempt at designing a DB schema that would support this was something like: product ------- id name description local_product ------- id product_id local_name local_description locale_id locale ------ id locale However, this solution requires a new local_ table for every table that contains name and description columns that require localization. In an attempt to avoid this overhead I redesigned the schema so that only a single localization table is needed product ------- id localization_id localization ------- id local_name local_description locale_id locale ------ id locale Here's an example of the data which would be stored in this schema when there are 2 tables (product and country) requiring localization: country id, localization_id ----------------------- 1, 5 product id, localization_id ----------------------- 1, 2 localization id, local_name, local_description, locale_id ------------------------------------------------------ 2, apple, a delicious fruit, 2 2, pomme, un fruit délicieux, 3 2, apfel, ein köstliches Obst, 4 5, ireland, a small country, 2 5, irlande, un petite pay, 3 locale id, locale -------------- 2, en 3, fr 4, de Notice that the compound primary key of the localization table is (id, locale_id), but the foreign key in the product table only refers to the first element of this compound PK. This seems like 'a bad thing' from the POV of normalization. Is there any way I can fix this problem, or alternatively, is there a completely different schema that supports localization without creating a separate table for each localizable table? Update: A number of respondents have proposed a solution that requires creating a separate table for each localizable table. However, this is precisely what I'm trying to avoid. The schema I've proposed above almost solves the problem to my satisfaction, but I'm unhappy about the fact that the localization_id foreign keys only refer to part of the corresponding primary key in the localization table. Thanks, Don

  • How do you move an admin menu item in Magento

    - by Josh Pennington
    I currently have an extension that I created and it currently sits inside of its own top level menu. I would like to move it so that the item would appear inside of the Customers menu. Does anyone know how to do this? It looks like this is handled inside the extensions config.xml file. The code that I have for it right now is as follows: <menu> <testimonials module="testimonials"> <title>Testimonials</title> <sort_order>71</sort_order> <children> <items module="testimonials"> <title>Manage Items</title> <sort_order>0</sort_order> <action>testimonials/adminhtml_testimonials</action> </items> </children> </testimonials> </menu> I tried changing the title element to Customers and it just created a duplicate Customers menu. Does anyone have any ideas? Thanks Josh Pennington

  • Hashtable is that fast

    - by Costa
    Hi s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]. Is the hash function of the java string, I assume the rest of languages is similar or close to this implementation. If we have hash-Table and a list of 50 elements. each element is 7 chars ABCDEF1, ABCDEF2, ABCDEF3..... ABCDEFn If each bucket of hashtable contains 5 strings (I think this function will make it one string per bucket, but let us assume it is 5). If we call col.Contains("ABCDEFn"); // will do 6 comparisons and discover the difference on the 7th. The hash-table will take around 70 operations (multiplication and additions) to get the hashcode and to compare with 5 strings in bucket. and BANG it found. For list it will take around 300 comparisons to find it. for the case that there is only 10 elements, the list will take around 70 operations but the Hashtable will take around 50 operations. and note that hashtable operations are more time consuming (it is multiplications). I conclude that HybirdDictionary in .Net probably is the best choice for that most cases that require Hashtable with unknown size, because it will let me use a list till the list becomes more than 10 elements. still need something like HashSet rather than a Dictionary of keys and values, I wonder why there is no HybirdSet!! So what do u think? Thanks

  • d3: Coloring Multiple Lines from Nested Data

    - by diet_coke
    I'm currently assembling some line graphs with circles at the datapoints from arrays of JSON objects formatted like so: var data = [{ "name": "metric1", "datapoints": [ [10.0, 1333519140], [48.0, 1333519200] ] }, { "name": "metric2", "datapoints": [ [48.0, 1333519200], [12.0, 1333519260] ] }] I want to have a color for each metric, so I'm trying to color them based on the index of the object within the array data. The code I have currently for just placing the circles looks like: // We bind an svg group to each metric. var metric_groups = this.vis.selectAll("g.metric_group") .data(data).enter() .append("g") .attr("class", "metric_group"); // Then bind a circle for each datapoint. var circles = metric_groups.selectAll("circle") .data(function(d) { return d.datapoints; }); circles.enter().append("circle") .attr("r", 3.5); Now if I change that last bit to something like: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i) { return i%2 ? "red" : "blue"; } I get alternating red and blue circles, as could be expected. Taking some advice from Nested Selections : 'Nesting and Index', I tried: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i,j) { return j%2 ? "red" : "blue"; } Which doesn't work (j is undefined), presumably because we are in the named property datapoints, rather than an array element. How might I go about doing the coloring that I want without changing my data structure? Thanks!

  • Java - How to declare table[i][j] elements as instance variables?

    - by JDelage
    All, I am trying to code a Connect4 game. For this, I have created a P4Game class and a P4Board class which represents the i X j dimensions of the Connect4 board. In P4Game, I have the following: public class P4Game{ //INSTANCE VARIABLES private int nbLines; private int nbColumns; private P4Board [][] position; //CONSTRUCTOR public P4Game(int nbLines, int nbColumns){ this.nbColumns = nbColumns; this.nbLines = nbLines; P4Board [][] position = new P4Board [nbLines][nbColumns]; //Creates the table to receive the instances of the P4Board object.*/ for (int i=0; i<nbLines; i++){ for (int j=0; j<nbColumns; j++){ this.position[i][j] = new P4Board(i,j); //Meant to create each object at (line=i, column=j) } } } This causes a NullPointerException in the nested loops where I mention this.position[i][j]. I reference those objects in other methods of this class so I need them to be instance variables. I suppose the exception is due to the fact that I have not listed the table element position[i][j] as an instance variable at the beginning of the class. my question to people here is (1) is my assumption correct, and if so (2) what would be the syntax to declare instance variables of this form? Thank you all for your help with what I realize is a very basic question. Hopefully it will also benefit other newbies. Cheers, JDelage

  • Why does Hibernate 2nd level cache only cache queries within a session?

    - by Synesso
    Using a named query in our application and with ehcache as the provider, it seems that the query results are tied to the session within the cache. Any attempt to access the value from the cache for a second time results in a LazyInitializationException We have set lazy = true for the following mapping because this object is also used by another part of the system which does not require the reference... and we want to keep it lean. <class name="domain.ReferenceAdPoint" table="ad_point" mutable="false" lazy="false"> <cache usage="read-only"/> <id name="code" type="long" column="ad_point_id"> <generator class="assigned" /> </id> <property name="name" column="ad_point_description" type="string"/> <set name="synonyms" table="ad_point_synonym" cascade="all-delete-orphan" lazy="true"> <cache usage="read-only"/> <key column="ad_point_id" /> <element type="string" column="synonym_description" /> </set> </class> <query name="find.adpoints.by.heading">from ReferenceAdPoint adpoint left outer join fetch adpoint.synonyms where adpoint.adPointField.headingCode = ?</query> Here's a snippet from our hibernate.cfg.xml <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property> <property name="hibernate.cache.use_query_cache">true</property> It doesn't seem to make sense that the cache would be constrained to the session. Why are the cached queries not usable outside of the (relatively short-lived) sessions?

  • Why aren't these Canvases rendering?

    - by bpapa
    I'm creating a web app that allows users to enter a number of colors, by specifying RGB values. Upon submission, the user will see a canvas with a solid rectangle drawn in the color chosen. On this page, I have 7 canvases. The first one draws just fine, but none of the rest show up. The browser is Safari. Here's the relevant code: First, the script element in the header, which defines the function I use to draw to the canvas. <script language="JavaScript" TYPE="text/javascript"><!-- function drawCanvas(canvasId, red, green, blue) { var theCanvas = document.getElementById("canvas" + canvasId); var context = theCanvas.getContext("2d"); context.clearRect(0,0,100,100); context.setFillColor(red,green,blue,1.0); context.fillRect(0,0,100,100); } // --> </script> Next, the HTML source, where I have my canvas tags and some embedded Javascript to call my drawCanvas function <canvas id="canvas0" width="100" height="100"> </canvas> <script language="JavaScript" TYPE="text/javascript"><!-- drawCanvas(0,250,0,0); // --> </script> . . //more source . <canvas id="canvas1" width="100" height="100"> </canvas> <script language="JavaScript" TYPE="text/javascript"><!-- drawCanvas(1,4,250,6); // --> </script> Also provided is a screenshot. As you can see, the "red" canvas comes up just fine, but the second one, which should be green, doesn't show up at all. Any ideas?

  • $HTTP_RAW_POST_DATA and Wordpress media_handle_upload

    - by BaronVonKaneHoffen
    Hi there! So I'm making something for which users need to upload images from a canvas element (on the front end) using Wordpress's in-built Media Upload API. I've successfully uploaded images with the API from a file input in a form: <input type="file" name="async-upload" id="async-upload" size="40" /> ... <?php $new_attach_id = media_handle_upload( 'async-upload', $new_id ); ?> and I've saved images from the canvas using my own script: <script type="text/javascript"> ... var img = canvas.toDataURL("image/png"); ... ajax.send(img ); </script> ... <?php $imageData=$GLOBALS['HTTP_RAW_POST_DATA']; $filteredData=substr($imageData, strpos($imageData, ",")+1); $unencodedData=base64_decode($filteredData); $fp = fopen( 'saved_images/canv_save_test.png', 'wb' ); fwrite( $fp, $unencodedData); ... ?> Problem is, Wordpress's media_handle_upload() only accepts an index to the $_FILES array for the upload. So the question is: How can I pass the image data from HTTP_RAW_POST_DATA to it? Could I make the $_FILES['tmp-name'] point to it somehow? Could I use another script as an intermediate step somehow? Could I unleash the monkeys on the typewriter until they come up with the answer? Any help very very much appreciated! Thanks, Kane

  • Fast serarch of 2 dimensional array

    - by Tim
    I need a method of quickly searching a large 2 dimensional array. I extract the array from Excel, so 1 dimension represents the rows and the second the columns. I wish to obtain a list of the rows where the columns match certain criteria. I need to know the row number (or index of the array). For example, if I extract a range from excel. I may need to find all rows where column A =”dog” and column B = 7 and column J “a”. I only know which columns and which value to find at run time, so I can’t hard code the column index. I could use a simple loop, but is this efficient ? I need to run it several thousand times, searching for different criteria each time. For r As Integer = 0 To UBound(myArray, 0) - 1 match = True For c = 0 To UBound(myArray, 1) - 1 If not doesValueMeetCriteria(myarray(r,c) then match = False Exit For End If Next If match Then addRowToMatchedRows(r) Next The doesValueMeetCriteria function is a simple function that checks the value of the array element against the query requirement. e.g. Column A = dog etc. Is it more effiecent to create a datatable from the array and use the .select method ? Can I use Linq in some way ? Perhaps some form of dictionary or hashtable ? Or is the simple loop the most effiecent ? Your suggestions are most welcome.

  • TEXTAREAs scroll by themselves (on IE8) every time you type one character

    - by Justin Grant
    IE8 has a known bug (per connect.microsoft.com) where typing or pasting text into a TEXTAREA element will cause the textarea to scroll by itself. This is hugely annoying and shows up in many community sites, including Wikipedia. The repro is this: open the HTML below with IE8 (or use any long page on wikipedia which will exhibit the same problem until they fix it) size the browser full-screen paste a few pages of text into the TEXTAREA move the scrollbar to the middle position now type one character into the textarea Expected: nothing happens Actual: scrossing happens on its own, and the insertion point ends up near the bottom of the textarea! Below is repro HTML (can also see this live on the web here: http://en.wikipedia.org/w/index.php?title=Text_box&action=edit) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <body> <div style="width: 80%"> <textarea rows="20" cols="80" style="width:100%;" ></textarea> </div> </body> </html>

  • W3 xHTML Validation Errors on jQuery code!

    - by Chris
    I have some jQuery code that, without it in the document it passes validation fine, but with it in it causes errors. The code in question is here: $.ajax({ type: "GET", url: "data.xml", dataType: "xml", success: function(xml) { //Update error info errors = $(xml).find("Errors").find("*").filter(function () { return $(this).children().length === 0; }); if (errors.length == 0) { statuscontent = "<img src='/web/resources/graphics/accept.png' alt='' /> System OK"; } else { statuscontent = "<img src='/web/resources/graphics/exclamation.png' alt='' /> "+errors.length+" System error"+(errors.length>1?"s":""); } $("#top-bar-systemstatus a").html(statuscontent); //Update timestamp $("#top-bar-timestamp").html($(xml).find("Timestamp").text()); //Update storename $("#top-bar-storename").html("Store: "+$(xml).find("StoreName").text()); } }); There are loads of other jQuery code on the page which all works fine and causes no errors so I cannot quite understand what is wrong with this. The page isn't "live" so cannot provide a link to it unfortunately. The error it lists is document type does not allow element "img" here And the line of code it points to is here: statuscontent = "<img src='/web/resources/graphics/accept.png' alt='' /> System OK"; It also has an issue with the next assignment to statuscontent

  • How can I remove a JPanel from a JFrame?

    - by Roman
    Recently I asked here how to add a new JPanel to JFrame. The answer helped me to get a working code. But not I have a related question: "How can I remove an old JPanel". I need that because of the following problem. A new JPanel appears appears when I want (either time limit is exceeded or user press the "Submit" button). But in several seconds some element of the old JPanel appears together with the component of the new JPanel. I do not understand why it happens. I thought that it is because I have to other threads which update the window. But the first thread just add the old panel once (so, it should be finished). And in the second thread I have a loop which is broken (so, it also should be finished). Here is my code: private Thread controller = new Thread() { public void run() { // First we set the initial pane (for the selection of partner). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generatePartnerSelectionPanel()); frame.invalidate(); frame.validate(); } }); // Update the pane for the selection of the parnter. for (int i=40; i>0; i=i-1) { final int sec = i; SwingUtilities.invokeLater(new Runnable() { public void run() { timeLeftLabel.setText(sec + " seconds left."); } }); try {Thread.sleep(1000);} catch (InterruptedException e) {} if (partnerSubmitted) {break;} } // For the given user the selection phase is finished (either the time is over or form was submitted). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generateWaitForGamePanel()); frame.invalidate(); frame.validate(); } }); } };

It crashes my program giving the following error : Program received signal: “0”. warning: check_safe_call: could not restore current frame I tweak my program and it can process a few more images before the error appear again. My coding is as follows: // parameters is an array where the fourth element contains a list of images in base64 >encoded string NSMutableArray *imageStrList = (NSMutableArray*) [parameters objectAtIndex:5]; while (imageStrList.count != 0) { NSString *imgString = [imageStrList objectAtIndex:0]; // Create a file name using my own Utility class NSString *fileName = [Utility generateFileNName]; NSData *restoredImg = [NSData decodeWebSafeBase64ForString:imgString]; UIImage *img = [UIImage imageWithData: restoredImg]; NSData *imgJPEG = UIImageJPEGRepresentation(img, 0.4f); [imgJPEG writeToFile:fileName atomically:YES]; [imageStrList removeObjectAtIndex:0]; } I tried playing around with UIImageJPEGRepresentation and found out that the lower the value, the more image it can processed but this should not be the way. I am wondering if there is anyway to free up memory of the imageStrList immediately after processing each image so that it can be used by the next one in the line.

  • How do I create a class repository in Java and do I really need it?

    - by Roman
    I have a large number of objects which are identified by names (strings). So, I would like to have a kind of mapping from object name to the class instances. I was told that in this situation I can use a "repository" class which works like that: Server myServer = ServerRepository.getServer("NameOfServer"); So, if there is already an object (sever) with the "NameOfServer" it will be returned by the "getServer". If such an object does not exist yet, it will be created and returned by the "getServer". So, my question is how to program such a "repository" class? In this class I have to be able to check if there is an instance of a given class such that it has a given value of a given field. How can I do it? I need to have a kind of loop over all existing object of a given class? Another part of my question is why I cannot use associative arrays (associative container, map, mapping, dictionary, finite map)? (I am not sure how do you call it in Java) In more details, I have an "array" which maps names of objects to objects. So, whenever I create a new object, I add a new element to the array: myArray["NameOfServer"] = new Server("NameOfServer").
