A function for getting data from the query string.

<!---Head--->
<script type="text/javascript"><!--
// Query string is:
// firstname=John&lastname=Doe
// Get value for 'firstname':
// var firstname = GetQuery('firstname');
// (The script automatically unescapes the value).

function GetQuery(arg){
var query = location.href.substring((location.href.indexOf('?') + 1), location.href.indexOf('#'));
if(location.href.indexOf('#') < location.href.indexOf('?')){
query = location.href.substring((location.href.indexOf('?') + 1), location.href.length);
}
if(location.href.indexOf('?') < 0){
query = '';
}
var querypairs = query.split('&');
var ret = '';
for(var i = 0; i < querypairs.length; i++){
var namevalue = querypairs[i].split('=');
if(namevalue[0] && namevalue[1] && namevalue[0] == arg){
while(namevalue[1].indexOf('+') >= 0){
namevalue[1] = namevalue[1].replace('+', ' ');
}
ret = unescape(namevalue[1]);
}
}
return ret;
}
