AJAX with POST

Hey all, At the risk of being told this is a PHP and not a JS list, but also knowing the discussions on this list, to the benefit of all I believe, very wildly, I'm posting this JS code snippet for some advice. As I posted earlier, my AJAX app that uses a GET to post to the server (and get a response), fails on IE with larger data, so I thought I'd take a shot at writing a POST function, but so far I can get it to get the data back, but the problem is by the time the data has come back the function has already returned null back to the calling function. What I need this function to do is wait for the data to come back and then send it back to caller. Here's the function. Any advice would be greatly appreciated. (The code to get the appropriate object per browser has been omitted.) http.open("POST", url, true); //Send the proper header information along with the request http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.setRequestHeader("Content-length", url.length); http.setRequestHeader("Connection", "close"); http.send(url); http.onreadystatechange = function() {//Call a function when the state changes. if(http.readyState == 4 && http.status == 200) { alert('['+http.responseText+']'); return (http.responseText); } } -- ==================================== Skip Evans Big Sky Penguin, LLC 503 S Baldwin St, #1 Madison WI 53703 608.250.2720 http://bigskypenguin.com ------------------------------------ Those of you who believe in telekinesis, raise my hand. -- Kurt Vonnegut
