Answer 1

Since you give us no information other than this one URL, you can do it very naively by simply:

> var uri = 'http://wallpapers.wapego.net/main.php?ses=SuNpnTR5PRYTkYXYN3syARtUHN7&f=3153038'
< undefined
> var foo = uri.split('&f=')[1]
< undefined
> foo
< "3153038"

Answer 2

Here's the code to get part of your current url.

var currentUrl = location.href;
var urlPart = currentUrl.substring((currentUrl.lastIndexOf("="))+1);
