  • W3C dom api in Java

    - by Benju
    Take a look at the example code... NodeList folderNodes = document.getElementsByTagName("Folder"); DocumentFragment node = (DocumentFragment) folderNodes.item(0); It was very easy to do "getElementsByTagName" on the document but when I want to do this again on the DocumentFragment it seems I cannot. How do I go about furthering this query?

  • Why won't this DOM element disappear?

    - by George Edison
    I have a page that uses jQuery with a small glitch. I managed to get this down to a simple example that demonstrates the problem: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function hideIt() { $('#hideme').fadeOut('slow', function() { $(this).remove(); } ); } </script> </head> <body> <div id='#hideme'>Hide me!</div> <button onclick='hideIt();'>Hide</button> </body> </html> As you would expect, the problem is simple: the caption doesn't disappear. What simple thing did I overlook? (Or if it's not a simple thing, what complicated thing did I miss?)

  • Windows Sidebar gadget - cannont access a div in Flyout DOM

    - by cyrix86
    In the main gadget html, there is a div with an onclick that calls this method in the Gadget script file: ShowFlyout = function() { System.Gadget.Flyout.show = true; var flyoutDoc = System.Gadget.Flyout.document; var mainFlyoutDiv = flyoutDoc.getElementById('divFlyout'); mainFlyoutDiv.innerHTML = "hello"; } Here is the Flyout html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>This is a flyout</title> <link href="Css\FlyoutStyle.css" type="text/css" rel="Stylesheet" /> </head> <body> <div id="divFlyout" > </div> </body> </html> The problem is that mainFlyoutDiv is always null. When peering into the System.Gadget.Flyout.document object through the debugger, the body parameter is null - I don't think that's right. The System.Gadget.Flyout.file value is being set elsewhere when the gadget first loads. What am I doing wrong? Also, does the System.Gadget.Flyout.show property have to be true before the System.Gadget.Flyout.document property can be accessed? My ultimate goal is to open a flyout and dynamically populate it's html

  • DOM Elements with same id and jQuery

    - by Steve
    Hi I have multiple elements with the same structure in my application. Second div element's id varies as per the comment id in the db which is unique. There are elements with the id 'vote_up' and 'vote_down'. This gets repeated for each comment.What happens is that, as I mentioned, there are multiple comments. I want to perform an Ajax request. First of this structure functions properly using ajax, but the rest does an http request. Btw I am developing a rails application and I am using jQuery. <div id="post_comment"> john<i> says </i> Comment<br/> <div id="comment_10_div"> **<form action="/comments/vote_up" id="vote_up" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[post_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote up" /> </form> <label id="comment_10">10</label> **<form action="/comments/vote_down" id="vote_down" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[place_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote Down" /> </form> </div> Can you please help me to solve this Thanks

  • Accessing an iFrame's dom from a Firefox Extension

    - by luisgo
    Hi all, I've spent a long time trying different things to get this to work but nothing does and documentation is not helping much. I'm trying to populate a form inside an iframe that I dynamically inject into a page. To inject that iframe I do: myObject.iframe = document.createElement("iframe"); myObject.iframe.setAttribute("src", data.url); myObject.iframe.setAttribute("id","extension-iframe"); myObject.window.document.getElementById('publisher').appendChild(myObject.iframe); myObject.iframe.addEventListener("load", function(){ myObject.populate(data); }, false); which works fine and DOES trigger the populate() method. My problem is getting the document or window objects for that iframe. I've tried all of the following: myObject.iframe.window myObject.iframe.document myObject.iframe.content but these are all undefined. I also tried passing the event object to that iframe's load event listener and then doing: event.originalTarget But that didn't work either. I am reading the following documentation: https://developer.mozilla.org/En/Working%5Fwith%5Fwindows%5Fin%5Fchrome%5Fcode https://developer.mozilla.org/en/Code%5Fsnippets/Interaction%5Fbetween%5Fprivileged%5Fand%5Fnon-privileged%5Fpages But either I'm not understanding it or it's just not properly explained. Can anyone shed some light? Thanks!

  • iframe accessing parent DOM?

    - by Yuval A
    How is it possible for a script within an <iframe> to have any notion of the page containing it? Can a script in the frame access any context outside of it? What about cross-domain? Up until now I believed an <iframe> is completely agnostic to the containing page, but I have seen an example which contradicts this belief. What exactly can and can't be done from within an <iframe> with respect to the containing page?

  • Android: DOM-Model to XML

    - by poeschlorn
    Hey Guys, analogue to this one (http://stackoverflow.com/questions/2788345/replacing-xml-in-file-from-document-in-java or http://www.exampledepot.com/egs/javax.xml.transform/WriteDom.html) I try to use it under Android... The problem is, that I can't use the suggested solution under android, because it throws java.lang.verifyError... After reading a little bit, I found out, that the class that was used to store the data to file, is not usable in android... can you suggest another solution, which is similar easy to use?

  • Why is setting HTML5's CanvasPixelArray values is ridiculously slow and how can I do it faster?

    - by Nixuz
    I am trying to do some dynamic visual effects using the HTML 5 canvas' pixel manipulation, but I am running into a problem where setting pixels in the CanvasPixelArray is ridiculously slow. For example if I have code like: imageData = ctx.getImageData(0, 0, 500, 500); for (var i = 0; i < imageData.length; i += 4){ imageData.data[index] = buffer[i]; imageData.data[index + 1] = buffer[i]; imageData.data[index + 2] = buffer[i]; } ctx.putImageData(imageData, 0, 0); Profiling with Chrome reveals, it runs 44% slower than the following code where CanvasPixelArray is not used. tempArray = new Array(500 * 500 * 4); imageData = ctx.getImageData(0, 0, 500, 500); for (var i = 0; i < imageData.length; i += 4){ tempArray[index] = buffer[i]; tempArray[index + 1] = buffer[i]; tempArray[index + 2] = buffer[i]; } ctx.putImageData(imageData, 0, 0); My guess is that the reason for this slowdown is due to the conversion between the Javascript doubles and the internal unsigned 8bit integers, used by the CanvasPixelArray. Is this guess correct? Is there anyway to reduce the time spent setting values in the CanvasPixelArray?

  • How to check for DOM equality with jQuery?

    - by Joseph
    I'm basically building a simple list, and one of the items in the list is selected. I'm accomplishing this by having a "selected" class applied to whichever item I want to have selected. I have two buttons that go forward and backward which traverse this list. However, when the user gets to the first or the last element in the list, I want to do a post back. This is where I'm stuck, because I'm having trouble identifying that the currently selected item is not the first or the last. Simple Example: <div id="list"> <p>item 1</p> <p>item 2</p> <p class="selected">item 3</p> </div> Let's say the user presses the next button, at this point I'm checking for something similar to this: if (jQuery('#list p.selected') == jQuery('#list p:last-child')) //do post back However, this logic is returning false, which leads me to believe I'm approaching this the wrong way. What is the best way for me to check for this kind of logic using jQuery?

  • Programmatically manipulating DOM element value doesn't fire onchange event

    - by Johan Fredrik Varen
    Hi all. I've got a hidden form field, and when a button gets pressed the value of the hidden field is changed. Now, I've added an observer to the hidden field, listening for changes to occur. For some reason, though, the event listener never kicks in, even though the value of the hidden element changes. I'm using Prototype and Firefox 3.6. The code looks roughly like this: button.observe('click', function(event) { hiddenField.setValue(someValue); }); hiddenField.observe('change', function(event) { alert('It works!'); }); Does anyone have a clue why the latter observer doesn't execute? Thanks!

  • Monitoring DOM Changes in JQuery

    - by user363866
    Is there a way to detect when the disabled attribute of an input changes in JQuery. I want to toggle the style based on the value. I can copy/paste the same enable/disable code for each change event (as I did below) but I was looking for a more generic approach. Can I create a custom event that will monitor the disabled attribute of specified inputs? Example: <style type="text/css">.disabled{ background-color:#dcdcdc; }</style> <fieldset> <legend>Option 1</legend> <input type="radio" name="Group1" id="Radio1" value="Yes" />Yes <input type="radio" name="Group1" id="Radio2" value="No" checked="checked" />No <div id="Group1Fields" style="margin-left: 20px;"> Percentage 1: <input type="text" id="Percentage1" disabled="disabled" /><br /> Percentage 2: <input type="text" id="Percentage2" disabled="disabled" /><br /> </div> </fieldset> <fieldset> <legend>Option 2</legend> <input type="radio" name="Group2" id="Radio3" value="Yes" checked="checked" />Yes <input type="radio" name="Group2" id="Radio4" value="No" />No <div id="Group2Fields" style="margin-left: 20px;"> Percentage 1: <input type="text" id="Text1" /><br /> Percentage 2: <input type="text" id="Text2" /><br /> </div> </fieldset> <script type="text/javascript"> $(document).ready(function () { //apply disabled style to all disabled controls $("input:disabled").addClass("disabled"); $("input[name='Group1']").change(function () { var disabled = ($(this).val() == "No") ? "disabled" : ""; $("#Group1Fields input").attr("disabled", disabled); //apply disabled style to all disabled controls $("input:disabled").addClass("disabled"); //remove disabled style to all enabled controls $("input:not(:disabled)").removeClass("disabled"); }); $("input[name='Group2']").change(function () { var disabled = ($(this).val() == "No") ? "disabled" : ""; $("#Group2Fields input").attr("disabled", disabled); //apply disabled style to all disabled controls $("input:disabled").addClass("disabled"); //remove disabled style to all enabled controls $("input:not(:disabled)").removeClass("disabled"); }); }); </script>

  • Recommendations on Triming Large Amounts of Text from a DOM Object

    - by aronchick
    I'm doing some in browser editing, and I have some content that's on the order of around 20k characters long in a <pre>. So it looks something like: <pre> Text 1 Text 2 Text 3 Text 4 [...] Text 20,000 </pre> I'd like to use jquery to trim it down when someone hits a button to chop, but I'm having trouble doing it without overloading the browser. Assume I know that the character numbers are at 16,510 - 17,888, and what I'd like to do is trim it. I was using: jQuery('#textsection').html(jQuery('textarea').html().substr(range.start)); But browsers seem to enjoy crashing when I do this. Alternatives?

  • Find three numbers appeared only once

    - by shilk
    In a sequence of length n, where n=2k+3, that is there are k unique numbers appeared twice and three numbers appeared only once. The question is: how to find the three unique numbers that appeared only once? for example, in sequence 1 1 2 6 3 6 5 7 7 the three unique numbers are 2 3 5. Note: 3<=n<1e6 and the number will range from 1 to 2e9 Memory limits: 1000KB , this implies that we can't store the whole sequence. Method I have tried(Memory limit exceed): I initialize a tree, and when read in one number I try to remove it from the tree, if the remove returns false(not found), I add it to the tree. Finally, the tree has the three numbers. It works, but is Memory limit exceed. I know how to find one or two such number(s) using bit manipulation. So I wonder if we can find three using the same method(or some method similar)? Method to find one/two number(s) appeared only once: If there is one number appeared only once, we can apply XOR to the sequence to find it. If there are two, we can first apply XOR to the sequence, then separate the sequence into 2 parts by one bit of the result that is 1, and again apply XOR to the 2 parts, and we will find the answer.

  • Getting XML Numbered Entities with PHP 5 DOM

    - by user343607
    Hello guys, I am new here and got a question that is tricking me all day long. I've made a PHP script, that reads a website source code through cURL, then works with DOMDocument class in order to generate a sitemap file. It is working like a charm in almost every aspect. The problem is with special characters. For compatibility reasons, sitemap files needs to have all special chars encoded as numbered entities. And I am not achieving that. For example, one of my entries - automatically read from site URLs, and wrote to sitemap file - is: http://www.somesite.com/serviços/redesign/ On the source code it should looks like: http://www.somesite.com/servi*ç*os/redesign/ Just this. But unfortunately, I am really not figuring it out how to do it. Source code file, server headers, etc... everything is encoded as UTF-8. I'm using DOMDocument and related extensions to build the XML. (Basically, DOMDocument, $obj-createElement, $obj-appendChild). htmlentities gives ç instead of ç str_replace does not work. It makes the character just vanish in the output. I was using $obj-createElement("loc", $url); on my code, and just now I read in PHP manual that I should use $document-createTextNode($page), in order to have entities encoding support. Well, it is not working either. Any idea on how to get unstuck of this? Thanks.

  • Get HTML DOM with CSS

    - by 2x2p1p
    CSS can apply styles in elements through one ID, class or pseudo-selector, but I would like to get the HTML tree, something like in javascript: <script type = "text/javascript"> window.onload = function () { var div = document.getElementsByTagName ("div"); div[0].style.backgroundColor = "gray"; div[0].style.padding = "20px"; } </script> So for example: <style type = "text/css"> div[0] { /* Wrong but i tried :( */ background-color: gray; padding: 20px; } </style> <div > <div>...</div> </div> I'm tired of assign IDs to millions and millions of elements; is there a way to do this?

  • XML DOM Manipuation

    - by kunalsawlani
    Hi, I am new to XML and have been trying some simple examples and they work fine. I want to do something like the following, but I am not able to figure out how to go about doing this. I have a HTML web page, where the user types in some data in an input field. I want to take that data, parse it to create an XML string, and the apply XSLT transformation to it, and display the result back on the page. All this needs to be done on the client browser, with JavaScript. If some one could point out the steps or the general procedure to go about doing this, it would be great. I have been looking over the net, but the information is so vast, that I have not been able to locate exactly what I need. Thanks

  • How to use Caret to tell which line it is in from JTextPane? (Java)

    - by Alex Cheng
    Hi all. Problem: I have CaretListener and DocumentListener listening on a JTextPane. I need an algorithm that is able to tell which line is the caret at in a JTextPane, here's an illustrative example: Result: 3rd line Result: 2nd line Result: 4th line and if the algorithm can tell which line the caret is in the JTextPane, it should be fairly easy to substring whatever that is in between the parentheses as the picture (caret is at character m of metadata): -- This is how I divide the entire text that I retrieved from the JTextPane into sentences: String[] lines = textPane.getText().split("\r?\n|\r", -1); The sentences in the textPane is separated with \n. Problem is, how can I manipulate the caret to let me know at which position and which line it is in? I know the dot of the caret says at which position it is, but I can't tell which line it is at. Assuming if I know which line the caret is, then I can just do lines[<line number>] and manipulate the string from there. In Short: How do I use CaretListener and/or DocumentListener to know which line the caret is currently at, and retrieve the line for further string manipulation? Please help. Thanks. Do let me know if further clarification is needed. Thanks for your time.
