$().ajaxStart not firing

Question

I have this at the top of my jQuery script:

   $().ajaxStart(function() {
      alert('ok');
   });

But the alert is not firing. All the other ajax is working, so I'm not sure why this isn't.

Answer 1

Please try this:

$(document).ajaxStart(function(){alert("aa");});

HTH

Answer 2

Try calling ajaxStart on document:

$(document).ajaxStart(function() {
    alert('ok');
});

$().ajaxStart worked before jQuery 1.4 but no more.
