Load Javascript into ajax loaded content

I am new to working with AJAX and have some experience with Java/Jquery. I have been looking around for an solution to my problem but i cant seem to find any.
I am trying to build a function in a webshop where the product will appear in a popup window instead of loading a new page.
I got it working by using this code:
$(".product-slot a").live('click', function() {
var myUrl = $(this).attr("href") + " #product-content";
$("#product-overlay-inner").load(myUrl, function() {
});
$("#product-overlay").fadeIn();
return false;
});
product-slot a = Link to the product in the category page.
product-content = the div i want to insert in the popup from the product page.
product-overlay-inner = The popup window.
product-overlay = The popup wrapper.
The problem that i now have is that my Javascript/Jquery isnt working in the productpopup. For example the lightbox for the product image or the button to add product to shoppingcart doesnt work. Is there anyway to make the javascript work inside the loaded content or to load javascript into the popup?
I hope you can understand what my problem is!
Thank you in advance!
EDIT: The platform im using has jquery-ui-1.7.2

I know this is an old thread but I've been working on a similar process with the same script loading problem and thought I'd share my version as another option.
I have a basic route handler for when a user clicks an anchor/button etc that I use to swap out the main content area of the site, in this example it's the ".page" class.
I then use a function to make an ajax call to get the html content as a partial, at the moment they are php files and they do some preliminary rendering server side to build the html but this isn't necessary.
The callback handles placing the new html and as I know what script I need I just append it to the bottom in a script tag created on the fly. If I have an error at the server I pass this back as content which may be just a key word that I can use to trigger a custom js method to print something more meaningful to the page.
here's a basic implementation based on the register route handler:
var register = function(){
$(".page").html("");
// use the getText ajax function to get the page content:
getText('partials/register.php', function(content) {
$(".page").html(content);
var script = document.createElement('script');
script.src = "js/register.js";
$(".page").append(script);
});
};
/******************************************
* Ajax helpers
******************************************/
// Issue a Http GET request for the contents of the specified Url.
// when the response arrives successfully, verify it's plain text
// and if so, pass it to the specified callback function
function getText(url, callback) {
var request = new XMLHttpRequest();
request.open("GET", url);
request.onreadystatechange = function() {
// if the request is complete and was successful -
if (request.readyState === 4 && request.status === 200) {
// check the content type:
var type = request.getResponseHeader("Content-Type");
if (type.match(/^text/)) {
callback(request.responseText);
}
}
};
// send it:
request.send(null); // nothing to send on GET requests.
}
I find this a good way to 'module-ize' my code into partial views and separated JavaScript files that can be swapped in/out of the page easily.
I will be working on a way to make this more dynamic and even cache these 'modules' for repeated use in an SPA scenario.
I'm relatively new to web dev so if you can see any problems with this or a safer/better way to do it I'm all ears :)

Yes you can load Javascript from a dynamic page, but not with load() as load strips any Javascript and inserts the raw HTML.
Solution: pull down raw page with a get and reattach any Javascript blocks.
Apologies that this is in Typescript, but you should get the idea (if anything, strongly-typed TypeScript is easier to read than plain Javascript):
_loadIntoPanel(panel: JQuery, url: string, callback?: { (): void; })
{
// Regular expression to match <script>...</script> block
var re = /<script\b[^>]*>([\s\S]*?)<\/script>/gm;
var scripts: string = "";
var match;
// Do an async AJAX get
$.ajax({
url: url,
type: "get",
success: function (data: string, status: string, xhr)
{
while (match = re.exec(data))
{
if (match[1] != "")
{
// TODO: Any extra work here to eliminate existing scripts from being inserted
scripts += match[0];
}
}
// Replace the contents of the panel
//panel.html(data);
// If you only want part of the loaded view (assuming it is not a partial view)
// using something like
panel.html($(data).find('#product-content'));
// Add the scripts - will evaluate immediately - beware of any onload code
panel.append(scripts);
if (callback) { callback(); }
},
error: function (xhr, status, error)
{
alert(error);
}
});
}
Plain JQuery/Javascript version with hooks:
It will go something like:
var _loadFormIntoPanel = function (panel, url, callback) {
var that = this;
var re = /<script\b[^>]*>([\s\S]*?)<\/script>/gm;
var scripts = "";
var match;
$.ajax({
url: url,
type: "get",
success: function (data, status, xhr) {
while(match = re.exec(data)) {
if(match[1] != "") {
// TODO: Any extra work here to eliminate existing scripts from being inserted
scripts += match[0];
}
}
panel.html(data);
panel.append(scripts);
if(callback) {
callback();
}
},
error: function (xhr, status, error) {
alert(error);
}
});
};
$(".product-slot a").live('click', function() {
var myUrl = $(this).attr("href") + " #product-content";
_loadFormIntoPanel($("#product-overlay-inner"), myUrl, function() {
// Now do extra stuff to loaded panel here
});
$("#product-overlay").fadeIn();
return false;
});

Jquery - Loading Animation Issue

I'm trying to display a loading image after an AJAX call has been made.
Currently I have the following Javascript code:
window.onload = function(){
var img = document.createElement("IMG");
img.src = "http://i.stack.imgur.com/FhHRx.gif";
function getCategories(){
$.ajax({
url: //url here,
dataType:'jsonp',
success: function(data){
//code here
},
statusCode: {
404: function() {
alert:('There was a problem with the server');
}
}
});
}
$(document).ajaxStart(function(){
alert('here');
var div = document.createElement("div");
div.id = "id1";
document.getElementById('id1').appendChild(img);
document.body.appendChild(div);
}).ajaxStop(function(){
var element = document.getElementById('id1');
element.parentNode.removeChild(element);
});
However, I am finding that the code is not even getting to the ajaxStart function as the alert is not appearing... I have tried other methods (eg: How to show loading spinner in jQuery?) to try and get this working but have not been successful as of yet...
Would anyone be able to help with this please?
Thank you.

You are more than likely getting an error for Unexpected Token, since you are declaring a function incorrectly.
Uncaught SyntaxError: Unexpected token {
You need to declare a function with either:
function getCategories () { }
Or:
var getCategories = function () { };

I think I found the solution here ($(document).ajaxstart not firing)
It seems that ajaxStart only works when XMLHttpRequest is used. If you use JSONP, XMLHttpRequest isn't used. Rather, it inserts a <script> tag to achieve this goal.
I simply used the workaround suggested in the above link.

Execute code after page is fully loaded using JavaScript

I tried for several hours to get the following code working.
The code should be paused until the page is loaded. The problem that I'm encountering is that the AJAX is executing asynchronously. How would I force the code to wait before executing?
var i = 1;
function On_Success(){
i = i+1;
if(i<=10){
$('<div id="p'+i+'">b</div>').replaceAll('#b');
$('#p'+i).load('tabelle.html');
//here shoul be waited, til the page is loaded
On_Success();
};
};
function knopf(){
$('body').append('<div id="p'+i+'">a</div>');
$('#p'+i).load('tabelle.html');
On_Success();
};

Both Ajax and load have an on successs function that can be run when the response is fully returned.
$.ajax({
async: true,
type: "GET",
url: url,
data: params,
success: function(html){
//do stuff here
},
error: handleAjaxErrors
});
If you want to use load, there is a success callback as well:
$("#myDiv").load('/ajax/data/get', function() {
//do stuff here
});

The load function has a success handler:
$('#p'+i).load('tabelle.html', function() {
On_Success();
});
The success handler is only called after the ajax call completes successfully, and after the provided content has been added to the DOM.
You can see full documentation here:
http://api.jquery.com/load/
If you also want to capture error conditions on the client you will need to use the full $.ajax call as per #Chris's answer.

.load accepts a callback that runs when loading is complete; you can use this instead of the more verbose jQuery.ajax function, which will require you to write additional code to populate your element.
jQuery("#p", i).load("tabelle.html", function() {
//code to run when tabelle.html has finished loading
});
Change your code to the following. It should work:
var i = 1;
function On_Success() {
i = i + 1;
if (i <= 10) {
$('<div id="p' + i + '">b</div>').replaceAll('#b');
$('#p' + i).load('tabelle.html', On_Success);
};
};
function knopf() {
$('body').append('<div id="p' + i + '">a</div>');
$('#p' + i).load('tabelle.html', On_Success);
};
On another note, is it absolutely necessary that you should wait for one load to complete before populating the other divs? Why can't you do something like this:
function On_Success() {
var i = 0;
while(i < 11) {
$('<div id="p' + i + '">b</div>').replaceAll('#b');
$('#p' + i).load('tabelle.html');
};
};
Also, I'm not sure what the knopf function is doing. What should the value of i be in that function? How are you calling your code?

read this xml with jquery

I'm having trouble reading this xml with jQuery.
http://jsfiddle.net/VLtqY/2/
XML:
<myElements type="AA" coID="A923">
<element1>01</element1>
<element2>02</element2>
<element3>03</element3>
</myElements>
I'm looking for the following output:
element1=01
element2=02
element3=03
A little help please.

First, you need to wrap your xml variable in a call to the jQuery function, as in $(xml). Then, a call to children() will get all of your target elements.
Here's a very basic (and sloppy), working example of iterating through the elements, but it's just the selector that needs changing:
var xml = '<myElements type="AA" coID="A923"><element1>01</element1> <element2>02</element2><element3>03</element3></typeData>';
var myOutput = $("#output");
myOutput.append("=== start ===<br />");
$(xml).children().each(function () {
var xmlnode = $(this);
myOutput.append(this.tagName + xmlnode.text() + '<br/>');
});
myOutput.append("=== end ===");
Working demo: http://jsfiddle.net/UByfW/2/

Try this
$('*', xml).each(function () {
replacing the the line
$(xml).find("myElements").each(function () {
or
$(xml).children().each(function () {
The reason is self-explanatory: you must fetch the children, not the root element.

You can use the jQuery parseXML (see docs) function to parse the string of XML into an XML document object. Just add this line somewhere between the variable declaration and your each loop:
xml = $.parseXML(xml);
The rest of it should work fine then. You can see an example here.

I would really suggest ajax for this. IE hates the way jquery grabs the xml.I have been using this for a very long time with lots of success and no problems.
$.ajax({
url: "path-to-file.xml",
dataType: ($.browser.msie) ? "text" : "xml",
success: function(data){
var xml;
if (typeof data == "string") {
xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.loadXML(data);
} else {
xml = data;
}
alert($(xml).find('element1').text());
alert($(xml).find('element2').text());
alert($(xml).find('element3').text());
},//END SUCCSESS
error: function(){
alert("Sorry, There was an error loading this information. Refresh the page or try again later. ");
history.go(-1);
}
});//END AJAX CALL
I know this looks like a lot, but it really isn't that bad. Put your path to your xml, in the .each() do what you want to do.

Jquery simple function

The aim of this code is to delete a comment with AJAX. The function is called as follows:
DeleteComment(166);
And the code that runs is:
// Each delete button
function DeleteComment(CommentID) {
$.ajax({
url: AJAXURL + "?action=del&id=" + CommentID,
success: function (data) {
// Parse the data
if (data.substring(0, 1) == "1") {
$('#cid' + CommentID).hide();
} else {
alert(data.substring(2, data.length));
}
}
});
}
However the $('#cid' + CommentID).hide(); line never fires as CommentID isn't retained, I'm new to Jquery, could someone show me how to change this so the comments ID is retained when the ajax success is called?

put the $('#cid' + CommentID).hide(); before $.ajax({ and then add $('#cid' + CommentID).show(); to your else condition..
Hide it first and then reshow it if deletion fails...
Not the most graceful solution, but the path of least resistance from where you are.

Can you post more of the surrounding code? As is, your code looks like it should work. But I see a troublesome comment: // Each delete button. The way you are binding the DeleteComment function to the buttons must not be working the way you assume.
Try this instead:
// Iterate over each delete button.
// The .each(...) provides you a function, a.k.a. local scope, for each button.
$(".deleteButtons").each(function (idx, el) {
// This is very important: you must create a local variable to hold the ID.
// How to get the ID is up to you.
var id = getTheCorrespondingCommentId(idx, el);
// Now you can safely pass the local variable to the DeleteComment function:
$(el).click(function() { DeleteComment(id); });
});
