There are two functions I find myself using all the time. They are very useful for javascript events that read the link href attribute to determine an action’s target.
function getHash() { var hash = window.location.hash; return hash.substring(1); // remove # } function getLinkTarget(link) { return link.href.substring(link.href.indexOf('#')+1); }
I’d use a regexp for the second, but those are very useful.

Nice work. Sometimes I use question marks after my hash to specify actions:

So this code is a useful extension of your function (useful to me at least!):
function getHash(excludeQuestionMark) {
if (typeof excludeQuestionMark == 'undefined') var excludeQuestionMark = true;
var hash = window.location.hash;
var stop = hash.indexOf('?');
// if there was no question mark in the hash, or if excludeQuestionMark is set to false
if (stop == -1 || !excludeQuestionMark)
var returner = hash.substring(1); // remove #
else
var returner = hash.substring(1,stop); // remove # and exlude everything after '?'
return returner;
}

hmm nice code however i was just looking for how to get the hash value so what does the second one do??

You can easily get the hash from a link with the `hash` property.
