If the url of a window/frame is like:

http://www.mysite.com/test.htm?param=hello&nextparam=world

Then you may use the location.search property of the window in script:

<script>
var data=location.search.substr(1);// gives everything after the '?'
var arr=data.split("&");// split into array delimited by '&'
for (i=0;i<arr.length;i++) {
arr[i]=arr[i].split("=");//further splits into 2-d array so that arr[0][0]="param" and arr[0][1]="hello"
}
// Now use the data
</script>

The above may not parse certain query strings correctly. It will also leave the name/value URL encoded. An alternative choice can be found at http://www.webdeveloper.com/forum/sh...d.php?t=162208
