I'm not following your PHP code here that well, but I have a different
suggestion. Rather than reloading the entire list, try removing the
element that's been deleted using Prototype locally (not bothering the
database for a completely new list).
So your list would look like this:
<li id="li_23">Some Text <span class="delete">remove</span></li>
<li id="li_25">Some Text <span class="delete">remove</span></li>
<li id="li_24">Some Text <span class="delete">remove</span></li>
<li id="li_28">Some Text <span class="delete">remove</span></li>
And your script:
var elm = evt.element();
var id = elm.up('li').id.split('_');
This decouples your HTML view from the database a little bit, but if
you were to refresh the page after a successful delete, you would see
the same thing anyway, so there's no real difference from a practical
standpoint. The benefit comes when you are performing this operation
on a thirty-screen-tall list of elements -- you no longer have to wait
for the entire list to come back to the screen, or for the browser to
