function getQuerystring(key, default_)
{
if (default_==null) default_="";
key = key.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regex = new RegExp("[\\?&]"+key+"=([^&#]*)");
var qs = regex.exec(window.location.href);
if(qs == null)
return default_;
else
return qs[1];
}
The getQuerystring function is simple to use. Let's say you have the following URL:
http://www.test.com?a=gopal
and you want to get the "a" querystring's value:
var author_value = getQuerystring('a');
