A simple example to use:
<script language= "JavaScript" >
<!--
var q = location.search.substr (1);
var qs = q.split ("&");
if (QS) {
for (Var i=0;i<qs.length;i++) {
Alert ("QueryName:" +qs[i].substring (0,qs[i].indexof ("=")) + "\nqueryvalue:" +qs[i].substring (qs[i].indexof ("=") +1) )
}
}
-->
</SCRIPT>
Examples in the Java authoritative guide:
function Getargs ()
{
var args=new Object ();
var query=location.search.substring (1);//Get query string
var pairs=query.split (",");//Break at comma
for (Var i=0;i<pairs.length;i++)
{
var pos=pairs[i].indexof (' = ');//Find Name=value
if (pos==-1) continue;//skipped if not found
var argname=pairs[i].substring (0,pos);//Extract Name
var value=pairs[i].substring (pos+1);//Extract value
Args[argname]=unescape (value);//Save As Property
}
Return args;//Object
