Sometimes when you have a very complicate URL, using server side langauge like PHP, ASP, or JSP may not get the URL queries easily. For example, one of my website address I have in my website consist two address where the 1st one is only the praser:

http://www.pcinvent.info/index.php?

option=com_wrapper&Itemid=94

&url=galleries/&g2_itemId=27312

So what I am tring to do is to change the "&g2_itemId=27312" to "?g2_itemId=27312" and then redirect......

Most of the server-side programming languages that I know of like PHP, ASP, or JSP give you easy access to parameters in the query string of a URL. JavaScript does not give you easy access. With javascript you must write your own function to parse the window.location.href value to get the query string parameters you want. Here is a small function I wrote that will parse the window.location.href value and return the value for the parameter you specify. It does this using JavaScript's built in regular expressions. Here is the function:

 
<script language="javascript">function gup( name )
{
  name = name.replace(/[[]/,"\\\[").replace(/[]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return results[1];
}</script>
<script language="javascript">
var query_param = gup('g2_itemId');
var runonce = gup('runonce');
if (runonce == "yes") {
}
else if (query_param) {
window.location="http://www.pcinvent.info/index.php?option=com_wrapper&Itemid=94
&url=http://www.pcinvent.info/galleries/?g2_itemId="+query_param+"&runonce=yes";
}
else {
}
 
</script>

But is there a way to just return everything after the ? as a string?

Is it necessary to be JavaScript on your task?
You may just use PHP session Get to get the query after the ?
It will be few lines instead of doing JavaScript in which require you to apply the Regular Expression.
Let me know if Client side language is a must like what I did above.
