Simply use a regular expression for it. /Room\.aspx\?RT=(\d+)/ does the job:

> /Room\.aspx\?RT=(\d+)/.exec('/Rate.aspx#/HotelMobileBooking/Room.aspx?RT=47')[1]
'47'

If you want to access the value in the current URL, use location.hash to access the #... part of the url.

Copied from the nodejs shell. Pretty much standard syntax to show that something was executed in an interactive interpreter (even though python's `>>> ` is more obvious). – ThiefMaster May 10 '12 at 08:32
Pardon me for asking i want to know the steps to do when the page first loads for Room.aspx because i am just a beginner at jquery – user1381205 May 10 '12 at 08:38
@user1381205. It has nothing to do with `jQuery`. – gdoron is supporting Monica May 10 '12 at 08:47

no need to use a regular expression. If RT is the only parameter in your querystring just use split()

url = ".../Rate.aspx#/HotelMobileBooking/Room.aspx?RT=47";
url.split("?RT=")[1]; //47
