Subject: [jQuery] Re: Get time of ajax post?
function now() { return (new Date).getTime(); }
// before the ajax call
var before = now();
// and in your ajax success callback:
var elapsed = now() - before;
Time is in milliseconds, but actual resolution is usually less, e.g. 15
millisecond resolution on a typical PC.

This is more of a JS queston in general than a jQuery
question: how do I get the time it took for an ajax post to complete?
I am trying to show a progress bar for an ajax post which may
take anywhere from 1 to 20 seconds. It's a multi-row
database table update. To do this I'm using the
"guesstimate" pattern described here:
http://ajaxpatterns.org/Progress_Indicator
To improve the accuracy, I'd like to do a "dummy" ajax post
to the server, get the amount of time it took, and use that
to calculate the total estimated time for the database
update, then do the actual multi-row update while the
progress bar is running.
I've seen timers for events in JS, such as the speed test
demos, but I can't figure out how to retrieve that
information from a completed ajax request.
Is what I'm trying to do possible?
