Ajax: replace cache value in URL when cache === false, type == get and key (_) already exists

I ran into an issue today where the ajax cache prevention parameter (_=(new Date()).getTime()) is being continuously appended to a URL.

I'm using livequery for an ajax call and after a few clicks, I end up with URL's that look like: http://mysite.com/mypage.html?_=1196716041523&_=1196716462963&_=1196716464245

My expectation would be that jQuery would look to see if this key already existed and if it did, replace the value with a new timestamp.

I've attached a patch. It could be optimized and perhaps changed to use a RegExp, but it works ;)

Thanks, Eric

Thanks - a much more elegant solution =)

There is one issue however, your replace is greedy and will match the rest of the query string. It just needs to be changed from: var ret = url.replace(/(\?|&)_=.*(&|$)/, "$1_=" + ts + "$2");

to: var ret = url.replace(/(\?|&)_=.*?(&|$)/, "$1_=" + ts + "$2"); add ? in front of (&|$)

Thanks, Eric

Sorry, I mean:

var ret = s.url.replace(/(\?|&)_=.*?(&|$)/, "$1_=" + ts + "$2");

That should be s.url.replace, not url.replace

Thanks for the catch! I actually had that in my test case and apparently it got lost getting in to jQuery. The fix is in [4007].
