jQuery: ajax call not received by IE

I have this simple ajax call. It works fine in firef开发者_StackOverflow中文版ox/chrome, returning number of messages sent in a chat enviroment without response. In IE however, the alert is called but only returns 0. If I set cache to false, it returns 1..

What might cause this? Is there any known issues regarding this operation in IE using jQuery?

IE will be taking the result from the cache. Since your request URL has not been changed IE interprets it to be the same request and will not fetch data from server.

You can set the cache property to false during the ajax request.

do you have function foobar() {

}

or

function foobar {

}

pretty sure you need the ()
