[TriLUG] Javascript ( and jQuery ) questions

[Scott Chilcote via TriLUG]

Hi Brian, 

This sounds a lot like something I did using Python and jQuery recently. One thing that I observed is that with Ajax the debugger breakpoints stop working, presumably because the transaction between the browser and the server has to run to completion. 

The part of your description that I don't understand is that it seems as if you are sending the accordion to the server. The accordion is a browser display widget. I requested the data that I needed from the server using Ajax, then used it to build tables to put in the accordion. 

The accordion object remained local to the browser. 

Does this sound like what you want to accomplish?
