/**
 * Parse hash bang parameters from a URL as key value object.
 * 
 * For repeated parameters the last parameter is effective.
 * 
 * If = syntax is not used the value is set to null.
 * 
 * #x&y=3 -> { x:null, y:3 }
 * 
 * @param aURL URL to parse or null if window.location is used
 * 
 * @return Object of key -> value mappings.

Thanks for this.

You can add support for full urls in # part, example '...#somepage.php?x=11&y=yes'

function parseHashBangArgs(aURL) {

aURL = aURL || window.location.href;
var vars = {};
var hashes = aURL.slice(aURL.indexOf('#') + 1).split('?');
if(hashes.length > 1) {
    vars['page'] = hashes[0];
    hashes = hashes[1].split('&');
} else {
    hashes = hashes[0].split('&');
}

for(var i = 0; i < hashes.length; i++) {
    var hash = hashes[i].split('=');
    if(hash.length > 1) {
        vars[hash[0]] = hash[1];
    } else {
        vars[hash[0]] = null;
    }
}

return vars;
