[Typo3-dev] ajax for popup menus

[Jeff Segars]

Hey Sebastian,
Thanks for the explanation.  After thinking about it a little more, I 
would say the need for a third-party library depends on how much we're 
trying to do with AJAX techniques.

If we're just creating the xmlHttpRequest object and working with one 
particular element on the page, then I agree that pulling something like 
prototype or sajax in is overkill.

When we start getting into heavy DOM manipulations that may work on a 
dynamic set of elements, I see more value in a third-party library.  It 
would hide all the browser inconsistencies and most likely provide a 
clean constructor or method that can be called easily to perform the 
manipulations.

For example, if I want make a link that performs an update of a single 
DOM element using prototype, I insert the following code javascript:

<a href="#" onclick="new Ajax.Updater('details_51', 
'/records/details/51', {asynchronous:true, evalScripts:true}); return 
false;">Details Views</a>

It doesn't do anything to simplify the server side of things but the 
client-side javascript is made much easier.

Thanks,
Jeff
