Doing Somthing When A DOM Element Is Dynamicaly Added?
Feb 9, 2010
I am creating a script that runs in tandom with several others. One of the other scripts creates and modifys the DOM on the fly.
My job is to write a script that will trigger some code when one of those DOM elements is created. The tag I have to watch for can be dynamically created, removed, and then created again with different childs, data, and subtags.
I have to log each of those newly created DIVs and all the child tags and data therein. I know how to do the logging, this is just an FYI. I know how to scan an existing DOM for the tags but not how to have a script monitor the DOM and fire off an event when these things are created on the fly.
I've been googling, yahooing, and asking for a day and a half now. Figured I'd start forum posting.

I've found a few posts on adding an event to a dynamic element, but that doesn't really help me. What I'm doing is allowing the user to add a textbox, then when a button is clicked i need to find the value for that text box, but it doesn't seem to pick up that the textbox is there.
Oh and that textbox is part of an array of textboxes, all of whose values i need.

I have a jQuery plugin that creates a list of news items and appends the <ul> to the element(s) calling the plugin. Each <li> gets a document key added to its data.
A brief snippet of the code:
(function
($){
$.fn.NewsList=function
(options){
[Code].....
None of the <li>'s have the data attached to them. I've tested the selector shown above in line 3, and it does pick up the correct <li>'s. The data is not visible in Firebug as it is on the other page. Both functions are called after document.ready and insert the elements after page load.
The onlydiscernible differences between these two circumstances is that in the working case, the plugin is called against an ID, whereas in the nonworking instance, it is called against a CLASS. In addition, in the working case, only one DIV is affected, and in the nonworking case, there are two DIVs that receive the treatment.

I have the following html:
<div id = "container"></div>
<div id = 'containerItemTmplt' class = "ui-widget-content">
<div class='contentHdr' onclick="test(this)" />
</div>
i then use jquery to clone 'containerItemTmplt' and add it to 'container':
var copiedElem = $('#containerItemTmplt').clone(true).
.attr('id', 'paneI1')
.appendTo('#container');
This works great and i confirm using I.E. 9's developer's tool utility that the element was indeed added with the correct id as a child of 'container'.
However in my test method, when i inspect the element that was copied, the id attribute is an empty string:
function test(elem)
{
var parentItem= $(elem).closest('div')[0];
alert(parentItem.id); //<--this displays an empty string despite
}

I am selecting an image as part of a html form. Once selected, jQuery assigns a user-defined attribute of the image to a hidden form variable and passes it to form handler. Problem is when I dynamically add images that can be selected. I am using live function to ensure that the dynamically added image is highlighted when clicked - but the user-defined attribute is not being grabbed by jQuery.
I think that when the page is first loaded, all the existing image attributes are loaded into the DOM, but when extra images are added with ajax, the DOM doesn't have the new attribute values, despite them appearing in the html on the page. I don't think I can use the live function in this instance, because an attribute is not an event. Out of ideas now. HTML/PHP, with jQuery:

In my application I render a couple of elements dynamically after the user selects an option in a dropdown list. When the user selects another option in the dropdown, I want to remove all the previous elements that was added dynamically. I've tried with the .Remove() function, but it seems the elements cannot be found in the DOM. I've looked a lot at the .live() events. Does anyone now how I can solve this?

I have been running the cycle plugin with success for a while, using 3 images, a caption, and a pager area (simple dots). I just added a fourth image/caption. the pager picks up the fourth image, adding a dot. However, it now fades in on transition, then immediately out. no other code changed other than the addition of a fourth image. why this is now malfunctioning?

I came up with some code to load javascript files dynamically. But I've got problems..
When the script element is dynamically added to the head section of html, i think that the document.ready event fires once again and therefore the code sort of runs twice.
In the html page I call this method:
In the script test.js I have the function SayHi():
The SayHi method never gets called and alert('begin') & alert('getScript') get called twice in this sequence:begin begin getScript getScript.

I am using GreaseMonkey to load jQuery 1.3.2 (there is a bug with the latest version of jquery and GM) and jQuery UI 1.8.0.I am using jQuery via GM to manipulate the GUI of a content management system. This CMS uses its own JS library to dynamically add stuff to the dom.
Question:How can I target a dom element that was added to the dom via this other JS lib?In other words, the CMS will add a div to the dom, and I am not sure how to tell jquery to wait for these elements to "be there" before applying the jquery goodness. Specifically, I would like to do this:
$(function() {
$('#zen1227').resizable();
});
But "#zen1227" does not "appear" until later via this other JS library.

i have a menu generated by a list with nested lists. i want the parent link to stay highlighted when the mouse hovers over the sub menus. because those sub menus are also generated by jquery (qtip), CSS alone won't do it (triedul.topnav li:hover a {background-color: #F00;}).is there a way to do this using jquery?

I'm a novice here, and I've got such a piece of code:
$(document).ready(function() {
$.each(includes, function(index, value) {
$('ul#menu-list').append('<li id="' + index + '"><a href="#">' + value + '</a></li>');
[Code]....
Basically, I load an html document on demand, through a menu populated with 'includes' values. Clicking on any item on the menu will load the appropriate document in the #content div and add an 'active' class to the menu item itself, to highlight it.
The loaded document optionally has inline links, that should load documents based on the same id's. Clicking on these inline links loads the appropriate document, but the 'active' class won't be added to the menu item having the same id of the inline link.
The thing I don't understand is that if I put (look at the line with arrows) any other value than 'id' (any valid integer or even 'id * 2') I get the desired result: a menu item having that id gets highlighted, a class being added to it.

I'm using the following to append code to a div:
var htmlCode = '<div id="secondDiv">Lorem ipsum dolor sit amet.</div>';
jQuery('#myDiv').append(htmlCode)
If i try later on to do something like:
jQuery('#secondDiv').get(0) // i get undefined
jQuery('#secondDiv') // i can't get the div element
Is it possible to get the appended elements this way? If not, how can i get these?

The requirement is, "save" operation should happen only when the form is "dirty". i.e., users should be able to save only when they modify something on the form.
For this, I'm using "dirty form plugin", which works fine even when new elements are added. It internally uses ".liveQuery()" for adding events to new elements but it is degrading the performance very badly, since our forms are very large. I'm trying to replace it with ".live" of jQuery 1.4.2, but have a problem.
When new elements are added, I want to store their initial values and on blur, i want to compare them with their latest values. I'm able to bind event handlers to new elements using ".live()", but I want to get notified when new elements are added, so that I can make the above check. Is there any way how I can check this?

I got a, perhaps very easy or perhaps not solvable question about the droppable function, I could not find anything about this so far. I got a basket, and a couple of products. The products are draggable and the basket is droppable. This of course is done in the $(document).ready(function(){} and works fine.
Now I got a button "add new basket" and if the user clicks on it, Javascript generates a new basket like this
function addElement() {
var content = document.getElementById('content');
var newbasket = document.createElement('div');
newbasket.setAttribute('id','basket2');
content.appendChild(newbasket);
}
And now of course the "basket2" div should also be droppable so that my products can be dropped there. But this does now work because the droppable + draggable settings were made in the "ready function" before the new "basket2" div was existing. Is there any way to perhaps reload the droppable + draggable settings that they also fit to the new basket or some other ways?
