UPDATE: Site is online

http://qwickqual.com/memorial/create/

under "Memoria Media" -> Click on "Our Videos" and it loads the list of categories click on any sub category and it goes through the process below

---------------- end edit ----------------------------------

UPDATED DESCRIPTION OF ERROR:

All code is based on <li> objects being linked
If I click on an <li> from the Initial page load to load:
  section 1: I can click on an <li> to load sub-categories

  section 2: I then click on an <li>, the query is made server returns section 3,
      section is not loaded to screen / and callback function is skipped over

perhaps someone has run into a similar issue before??

---------------- end edit ----------------------------------

I've also added comments to the code


I have a jquery function that is setup to load categorized lists of thumbnails. So far the function is in use in 3 location. Each of them generates HTML using the same template under django. The function works perfectly in 2 of the 3 locations, and I"m plain stumped as to why the 3rd won't work.

Below is the complete set of relevant javascript, the page load HTML for the relevant section. And 2 examples of HTML that is loaded through the script,

1 of them works, 1 of them doesn't and both are loaded into the same page load HTML

Any ideas what I'm missing here? Or information I need to add to help debug? Currently posting this to a live server to interact with, been local only till now...


Error: Script works properly through all levels of title="our_photos" Script loads 1st level of title="our_videos"

Script will not load sub-category of title="our_videos"

Example: From HTML below: Click on Script will query the server properly: GET http://localhost%3A8000/memorial/media%5Ftype/our%5Fvideos/4/

Script will not load the returned HTML into the #select_media div

scopeChain: [Call, Call multi=false uri=/memorial/media_type/our_videos/, Window # 0=Call 1=Call 2=window]

relative vars: label = "our_videos" wrapper = "media" uri = "/memorial/media_type/our_videos/" multi = false

Javascript

<script type="text/javascript">
// this piece is where I'm having trouble in the grand scheme of things
// label = piece of class tag
// wrapper = tag to load everything inside of
// uri = base of the page to load
// multi = not relevant for this piece but needed to pass on to next function
function img_thumb_loader(label, wrapper, uri, multi) {
    if(!(wrapper)) { wrapper = label }
    $('.'+label+'_category').click(function () {
// show the loading animation
        $('div#'+wrapper+'_load').show();
// get var of current object
        type = $(this).attr('title') || '';
// load it into the screen - this is the error
// when I click on an <li> from section 2 below it will query server
// (Tamper data & server see it - & return section 3 below
// But will not load into the screen on return
// also skips over the callback function
