Why i can't save the return value of XMLHTTPRequest in a variable?

[web_designer_iq]

Hi
This code is working perfectly:

XMLHttpRequestObject.onreadystatechange = function() 
{ 
if ( XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200 ) {
    obj.innerHTML = XMLHttpRequestObject.responseText; 
 }
} 

But i need to store the responseText value in a variable like this:

var resText = XMLHttpRequestObject.responseText; 

any idea please?

that should work perfectly fine. It's the way I do it.
