Sadly, I talready ried this and hit what appears to be another
problem. "handle()" (or my equivalent function) came up as undefined
according to Firebug when I tried to call it inside the callback
function.
It may be because my Javascript code is within the <body> of the HTML
file (due to reasons out of my control) rather than the <head>. Maybe
I can't use functions this way inside <body>. Or maybe it's same old
asynchronous problem with Ajax.
