CODE: Ajax Code

Copy / Restore

function ajax(url, get_value, post_value){
this.url = url ? url : "http://www.somesite.com/getsomething.php" ;
this.get_value = get_value;
this.post_value = post_value;
this.response = null;
try{
// Firefox, Opera 8.0+, Safari
this.xmlHttp = new XMLHttpRequest();
}
catch (e){
// Internet Explorer
try{
this.xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e){
this.xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
}
this.getData = function(wat){
// alert(wat);
if (this.xmlHttp.readyState == 4){
return this.xmlHttp.responseText;
}else if(this.xmlHttp.readyState == 1 || this.xmlHttp.readyState == 2 || this.xmlHttp.readyState == 3){
return this.xmlHttp.readyState;
}
}
this.url += "?ran=" + Math.random() + "&get=" + get_value;
this.xmlHttp.onreadystatechange = this.getData("trapped");
this.xmlHttp.open("POST",this.url,true);
this.xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
this.xmlHttp.send(post_value);
}

CODE: Creating Object	Copy / Restore :: Remove Scroll Bars
ajaxController = new ajax(null, get_value, post_value); alert(ajaxController.getData("free") );

All fairly straightforward except for one thing, see that alert(wat) in ajax.getData()? If I comment that out it returns 1 (the readystate), if I leave it to execute the response returns what it's supposed to (i.e. the readystate reaches 4).

The only difference between commenting out the alert() and leaving it in is the amount of time before the script reaches the if/else statement. In other words the script is executing too fast meaning it doesn't allow the readystate reach 4 before it moves on. Any way around this? It's a real pain in the ass, it seems like it should work but won't. Any help appreciated.
