Works in FF but not IE

[Tandem]

I'm just trying to grasp the basics of AJAX here, using the below code with an onclick doing the sendRequest. It works completely fine in Mozilla FireFox but not at all in IE7, which says "Error on page" on the bottom left bar.

 

function createRequestObject() { 
   var req; 
   if(window.XMLHttpRequest){ 
      // Firefox, Safari, Opera... 
      req = new XMLHttpRequest(); 
   } else if(window.ActiveXObject) { 
      // Internet Explorer 5+ 
      req = new ActiveXObject("Microsoft.XMLHTTP"); 
   } else { 
      // There is an error creating the object, 
      // just as an old browser is being used. 
      alert('Problem creating the XMLHttpRequest object'); 
   } 
   return req; 

} 

function handleDivTag(divtag) 
{ 
   var divtag; 
   return divtag; 
} 

// Make the XMLHttpRequest object 
var http = createRequestObject(); 


// Create the Divtag Handler -- Mainly an IE 6 Fix 
var divhandler = new handleDivTag(null); 

function sendRequest(act,divtag) { 
   // Open PHP script for requests 
   http.open('get', 'pstatsajax.php?act='+act); 
   http.onreadystatechange = handleResponse; 
   divhandler.divtag = divtag; 
   http.send(null); 
} 

function handleResponse() { 

   if(http.readyState == 4 && http.status == 200) { 
    
      // Text returned FROM the PHP script 
      var response = http.responseText; 

      if(response) { 
         // UPDATE ajaxTest content 
         document.getElementById(divhandler.divtag).innerHTML = response;
      } 

   } 
}

 

 

 

Any Suggestion as why it's not working would be great. Thanks.

Can you also post the detail of the error along with the line number?

 

I'm not sure this gonna fix it, but the 'open' function requires 3 arguements:

 

http.open('get', 'pstatsajax.php?act='+act, true);
