On load, check what #hash tag there is in the url, and then

I'd like to load a url with a ha开发者_C百科shtag and grab it to be used in javascript.

Ie, say you load www.url.com/#1, I would like to be able to do something like the following in JS:

var hash_value = get_the_hash_value();

do_something_with(hash_value);

How does one perform something like this?

window.location.hash
