Ajax anomaly ? (no wonder what I do, I cannot set the variable

[2levelsabove]

look at variable "test". i have tried to set it up everywhere. I get a successful response but it just does not like to set a variable.

 

 

 

function isSpecBook(fileid)
{
var test = "test";

      if (window.XMLHttpRequest) {
		var req = new XMLHttpRequest();
	}
	else if (window.ActiveXObject) {
		var req = new ActiveXObject("Microsoft.XMLHTTP");
	}


req.open("GET", "include/_process/isSpecBook.php?FileID="+fileid+"&json=1", true);
	req.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
	req.send(null);	


	req.onreadystatechange = function() {
		test = "success";


		if ((req.readyState == 4) && (req.status == 200)) {
			if (req.responseText.length) {
			test = "success";
				//var jsonSpec = eval('(' + req.responseText + ')');
				 if (req.responseText == "success"){

					test = "success";

				 }


			}
		}

	test = "success";                                     }//////req.onreadystatechange = function() {

return test;

}//function
