Question

Is there anyway to see how long a simple $.getJSON method takes to call using some type of timing code, in jquery/javascript?

Secondly, is there any way to see how BIG the response Content-Length is, in kB or megabytes?

Answer 1

If you want pure javascript, right before you send the request note the time using new Date().getTime();

Then in the ajax callback, note the time again, and subtract against the first time. That will give you the length of the call.

Something like this:

function aCallback()
{
   window.time2 = new Date().getTime();
   window.alert(window.time2 - window.time1)
}
window.time1 = new Date().getTime();
$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: aCallback
});
