[Javascript] Ajax question

[billy reisinger]

Someone may have already mentioned this, but I believe the ajax
request object has an "oncomplete" handler in every browser
implementation.  You could always send the ajax request and then set
the window.location to whatever value when the ajax oncomplete event
fires.  That way you can be sure that whatever action was supposed to
happen via ajax actually completes before you change pages.  Something
like this?

requestObj.onComplete = function() {
    window.location = "http://somewhere";
}
requestObj.send();

I dunno, maybe I'm not understanding your problem exactly.
