How do you get querystring using YUI 2 ?

Question

I need to get the a parameter passed via a querystring. I need to get the value of the parameter and then use it in some javascript.

In my specific example, I am using the "tabview" object and would like to set the "selected" tab by getting it from the querystring. The querystring would be something like this

http://www.myserver.com/pagex.html?tab=3

So, I want to get the "tab" parameter and extract the value to preset the tab on form i am displaying..

Thanks..

It's well hidden in the History module.

If you have a page at a url like:

http://my.site.com/foo.html?QUERY=bar&OTHER=stuff

Then you can get the value for QUERY using:

var string = YAHOO.util.History.getQueryStringParameter('QUERY'); //returns "bar"
