Shift js string single character

Question

In PHP, it's pretty simple, I would suggest array_shift($string)?

If not, I'm sure there is an equally simple solution :)

However, is there a way to achieve the same in JavaScript?

My specific example is extracting window.location.hashfrom the address bar to dynamically load a specific AJAX page. If the hash is 2, that is, http: //foo.bar.com#2 ...

var hash = window.location.hash; // hash would be "#2"

Ideally, I would like to remove #so that the function is simple 2.

Thank!
