[jQuery] Get parameters from URL

[ReynierPM]

Hi every:
It's possible to get values from URL with jQuery like PHP? For example 
suppose you have this URL: form.html?s=ok&val=rperezm. In PHP is simple:
[code]
 echo $_GET['s']; // return ok
 echo $_GET['val']; // return rperezm
But I don't know if this is possible in Javascript and also with jQuery. 
Can any body guide me on this?
Cheers and thanks in advance
