Cannot Locate Dynamically Loaded Control With GetElementById
Aug 3, 2011
I'm having a problem with some dynamically loaded content.
1. Ajax request returns some content that goes in a div. Inside that content, there's a text box with the id "coupon"
2. Also inside that content is a script called add_coupon that sends another ajax request. Use pushes a button, function gets called, all is well.
3. Inside the function, "document.getElementById ( 'coupon' )" returns undefined.
@ page.load the init() function on this page will find everything just fine. However if I call init() after the load it does not find the referenced controls. My goal is to set the imageurl in the hidden "imageurl" textbox, then call init from the treeview to reload the image. Not rocket science, IF I could get it to find the controls.
What I don't get is the results from the "get objects" text box I put at the top. If I look though all the elements on the page, shouldn't I see a heck of a lot more than this?
My Full code is::- ---------------------------------------------------------------------------- $(document).ready(function() { //First Method $("button").click(function() { var bid= $(this).attr('id');
So i have a javascript function which clones a Node on my page. That part works fine, as does the renaming of all the controls. The part that i do not understand, and cannot get to work is that several of the controls have an onclick event. On the dynamically created controls this onclick does not fire. Does anyone know why this would be, or possibly how to get around it?
Each time I dynamically load the options of a select box and then try to do anything with it (such as clicking it or using other JS code on it) I get the following Firefox error:Error: Index or size is negative or greater than the allowed amount = NS_ERROR_DOM_INDEX_SIZE_ERR
I am using the following code:<select id="day" name="day"></select> <script language="javascript"> var options_list = new Array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31); selectbox_element = document.getElementById('day'); selectbox_element.options.length = 0; // Remove any previous values.
for (var i = 0; i < options_list.length; i++) { selectbox_element.options[i] = new Option(options_list[i], options_list[i]); } </script>
The "options_list" array is filled beforehand using a simple PHP for() loop.
If I create the exact same options but do so by writing them into the HTML using PHP, then I don't see the error message anymore.
This problem happens in both Firefox 1.5 and Internet Explorer.
I'm trying to add dynamically generated HTML after the page has loaded. I've tried two versions.The latest versions is this, using insertBefore (as appendChild is buggy in a few browsers according to the SitePoint reference) ...
Code:
addImageField: function(x) { var newNode = createImageField(x); var src = document.getElementById("imageUploads");
[code]...
The first alert returns: object HTMLFieldsetElement .The second alert returns: object HTMLDivElement....and the third alert fails to fire, indicating a problem with the code above.Note that if I change the problem line to remove the null reference it still doesn't work (again the third alert won't fire):
Is there a way to know when a function is available for me to call it from a dynamically loaded a javascript?
I use this code to load the include.js file and then I call testIncludeFn() from it:
<code>
var html_doc = document.getElementsByTagName('head').item(0);
var file = document.createElement('script'); file.setAttribute('language','javascript'); file.setAttribute('type','text/javascript'); file.setAttribute('src','/include.js'); html_doc.appendChild(file);
// here I would like to be able to wait for the script to become available
testIncludeFn();
</code>
It works in IE and sometimes I get it to work in FF 1.5, but I would like to have a way of reliably calling testIncludeFn(). Can I pool somehow the DOM to see if the load completed. How?
When I load an HTML file dynamically which contain relative links with jQuery, all the links are broken. which does not involve changing all the links to absolute values?
I have a page that contains images, and those images are displayed in a fancybox window when they are clicked. Some of these images are loaded dynamically after the page loads via AJAX.
All of the images exist inside of link tags with class="challenge_image_gallery". The code works the way it should on the images that are initially loaded on the page. However, when the new images are loaded onto the page using AJAX, the fancybox window loads two instances of the image that was clicked on rather than one as it should.
I have a js application, that loads formular-markup dynamically for a specific entity. Is there a way to access elements within this dynamically loaded markup through jquery?
eg. in the form load function: $('#container').empty().append($(entityForm.markup).addClass ("formContainer"));
I have seen similar problems in the forum, but none that match this issue exactly.
I am using Giva Labs' jNotify plugin [URL].I have a main page that dynamically loads content in a container.
I load jquery, and jnotify in the main page. When I call jnotify from thedynamicallyloaded content, I get an error that jnotify is not a valid method. If I include the <script> call for jnotify in the dynamically called content, it works. This does not seem like the best practice.
Is there a way to re-initialize jnotify afterloadingdynamiccontent?
I have a site that shows off video clips. When a clip is 'clicked' the video and related data is loaded in using jQuery. The page does not refresh. I now need to link directly to different 'videos', but am unable to because a click hasn't taken place to load the video in. It just loads the categories page. What would be the best way to allow me to link directly to the video... ? Will I need to edit my .htacess file? Will I need to somehow work out what clip they are trying to get, and 'fake' a click to impose the video/data on the page?
The following code adjusts the opacity of an image which were dynamically loaded. It works on all browsers except for IE6.However, jQuery did apply inline styles "FILTER: alpha (opacity=30); ZOOM: 1" on the image. It just doesn't work.

OK, I am very new to jQuery so bare with me here. I am trying to get the document body height and set it as the height of a table, after the page has been loaded. Below is an example of what I am trying to do.
[Code]...
I am not sure where to place the jQuery code, before or after the table tag...and I am not even sure if any of my jQuery code is correct. Once again, i need to set the table height AFTER the document has been loaded and then dynamically change the height of the table.
I've been trying to get this page working with dynamically loaded iframe sources passed by URL, but I can't seem to get it working.Here's the relavent code:
<script type="text/javascript"> function delineate(str) { URL = str.indexOf("=") + 1;[code]...
I used the hidden form to change the url to text - advice from another website. I'm sure there are better ways to do it, but I'll explore them as soon as this thing actually works..The types are in a subfolder named types, as shown. The document.write was placed in as a debug helper, and it displays the proper file location of whatever I select with the combo box, but the iframe doesn't change it's src to the selected page! I've tired the last line of the last <script> with several different methods, none of them producing any effect whatsoever.
know why flash doesn't work on content dynamically loaded via AJAX? This is for a one-click CopyToClipboard function. I use ZeroClipboard for this. HTML CODE (this works perfect with the clipboard() function)
Code: <label>Image link: </label><input id="photo_direct_link" value="test" /> CLIPBOARD FUNCTION Code: function clipboard() { // Copy to clipboard var photo_direct_link = new ZeroClipboard.Client(); [Code]...
I am in a little over my head here trying to make a template for this PHP script. I am trying to work out all javascript errors.
So far I only have one error on the index page and no other pages. In IE8 at the bottom it shows me the little error icon and when I click it, it shows me:
Line: 2 Char: 18579 Error: Object doesn't support this property or method Code: 0 URL: http://www.mysocialengine.com/demo/woolton/index.php
I am trying to locate this error in the source code, but cannot figure it out. Can someone maybe take a look at the source and point me in the direction to what IE8 is finding as an error? It's weird that there are javascript errors only on the home page when I use the same header and footer file for the entire web site.
