Hi im trying to calculates the time taken to completely download and render the contents of the IFRAME and display it in a DIV element. And refresh the contents of the IFRAME with a button and recalculate the time and display it in the same DIV element.

I have managed to refresh the contents of the IFRAME and but display the load time of the window not the IFRAME.

code is listed below

XML

<html>
<head>

<script type="text/javascript">

//calculate the time before calling the function in window.onload
beforeload = (new Date()).getTime();
function pageloadingtime()
{

     //calculate the current time in afterload

    afterload = (new Date()).getTime();


     // now use the beforeload and afterload to calculate the seconds
    secondes = (afterload-beforeload)/1000;


    document.getElementById("loadingtime").innerHTML = "<font color='red'>(You Page Load took " + secondes + " seconde(s).)</font>";

}

window.onload = pageloadingtime;



</script>

<script type="text/javascript">

function Reload() {
var f = document.getElementById('iframe1');
f.src = f.src;
}

</script>

<title>load time</title>
</head>


<body>

<div id="loadingtime"></div>

<br>

<iframe id="iframe1" width="800" height="350" src="http://google.com"></iframe>
<br>

<input type="button" value="Reload" onClick="pageloadingtime()" onClick="Reload();">

<br>

The problem you are having is that you are using window.onload and not the iframe's onload attribute. The input button triggered both Reload() and pageloadingtime() which is also a big no no. I fixed your code by moving the setting of beforeload also into Reload() and attaching the trigger to iframe's onload attribute:

XML

<html>
<head>

<script type="text/javascript">

//calculate the time before calling the function in window.onload
beforeload = (new Date()).getTime();
function pageloadingtime()
{

     //calculate the current time in afterload

    afterload = (new Date()).getTime();


     // now use the beforeload and afterload to calculate the seconds
    secondes = (afterload-beforeload)/1000;


    document.getElementById("loadingtime").innerHTML = "<font color='red'>(You Page Load took " + secondes + " seconde(s).)</font>";

}

//window.onload = pageloadingtime;



</script>

<script type="text/javascript">

function Reload() {
    beforeload = (new Date()).getTime();
    var f = document.getElementById('iframe1');
    f.src = f.src;
}

</script>

<title>load time</title>
</head>


<body>

<div id="loadingtime"></div>

<br>

<iframe id="iframe1" width="800" height="350" src="http://google.com" onload="pageloadingtime();"></iframe>
<br>

<input type="button" value="Reload" onClick="Reload();">

<br>


</body>
</html>

Have fun!
