ASP.NET UpdatePanel, Ajax, and jQuery problems and solution

I am finishing work on an eCommerce application and there is some AJAX functionality that I had to add to several of the pages.

Prior to this, I was adding some behaviors to elements of the page using jQuery's ready function:

// inside my script.js file
jQuery(function($) {
$(document).ready(function(){
   // code here
}});

I added several UpdatePanels that were being updated by some AJAX calls. Everything seemed to work great, until I noticed that once any of the AJAX updated the UpdatePanel that all the behaviours I was setting up using jQuery were gone!!

I spent a while digging around and found a comment by "gt1329a" here:

In his/her comment they mention that "pageLoad fires after every partial postback" - which was essentially resetting the page without re-initializing the jQuery $(document).ready()...

So to clarify his/her "quick and dirty solution", I modified the code so it looks like this:

// inside my script.js file
/* // sorry jQuery
jQuery(function($) {
$(document).ready(function(){ */

function pageLoad()
{
   // code here
}

/*}});*/

I have some concerns about doing this, but being a pragmatist, I am satisfied with the result. The AJAX calls all work, and all the behaviors I need to add into the page are functioning as expected.

Please comment if this post is helpful.

Another day lost due to Internet Explorer 7. Thanks IE.

I've had to find this solution twice, and both times it has cost me dearly - so I am posting here for as much my benefit as anyone else's.

Scenario: Calling a JavaScript function from within Flash using ExernalInterface when Flash is in a form.
Problem: IE7 throws an error when we call ExternalInterface. The error says "player is not defined" - "player" is the id I use for my flash object.
Reason: Apparently, IE can't find an object by ID within the DOM if that object is within a form.
Solution: At the end of the javascript that I use to write out the flash tags, I put this line of code:
player = document.getElementById('player');

Here is a better explanation and the solution (see the comment by IsaacTheIceMan from 19 Oct 2007)
