Mike, how are you running the script? Did you just download it and open up the html file in your browser? If so, that could be your problem was the XHR command will fail. If you don't have FireBug installed, install it and see what the XHR call is doing.

i have this new code that is ajax and refreshes the page every few seconds but still has a flicker in ie the url to this is http://220.245.192.227/test/ticker

code:
index.php

Code:

<head>
<script type="text/javascript">
var page = "test2.php";
function ajax(url,target)
 {
    // native XMLHttpRequest object
   document.getElementById(target).innerHTML = '';
   if (window.XMLHttpRequest) {
       req = new XMLHttpRequest();
       req.onreadystatechange = function() {ajaxDone(target);};
       req.open("GET", url+"?sid="+Math.random(), true);
       req.send(null);
   // IE/Windows ActiveX version
   } else if (window.ActiveXObject) {
       req = new ActiveXObject("Microsoft.XMLHTTP");
       if (req) {
           req.onreadystatechange = function() {ajaxDone(target);};
           req.open("GET", url+"?sid="+Math.random(), true);
           req.send();
       }
   }
         setTimeout("ajax(page,'scriptoutput')", 2000);
}

function ajaxDone(target) {
   // only if req is "loaded"
   if (req.readyState == 4) {
       // only if "OK"
       if (req.status == 200 || req.status == 304) {
           results = req.responseText;
           document.getElementById(target).innerHTML = results;
       } else {
           document.getElementById(target).innerHTML="ajax error:\n" +
               req.statusText;
       }
   }
}
</script>
</head>
<body onload="ajax(page,'scriptoutput')">
<span id="scriptoutput"></span></p>
</body>

i really want it to refresh the page automaticalyl with no flicker effect when the text is updated inside the text file store/mike.txt is it possible?

**paul_wilkins** · Apr 13, 2008 03:24

No, it is not possible to refresh the IE page without the flicker. Their browser isn't made to work that way.

**Mike4x4s** · Apr 13, 2008 03:38

so are you saying with ajax always images will flicker? no matter what and there is no way around it

**paul_wilkins** · Apr 13, 2008 03:46

When using proper ajax techniques that's not an issue.
If the page is flickering then something else may be going on.
I shall bow now to ajax experts who may come along.
