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;
}
