Very Straightforward!

function parseQueryString(){
    var assoc = {};
    var keyValues = location.search.slice(1).split('&');
    var decode = function(s){
        return decodeURIComponent(s.replace(/\+/g, ' '));
    };

    for (var i = 0; i < keyValues.length; ++i) {
        var key = keyValues[i].split('=');
        if (1 < key.length) {
            assoc[decode(key[0])] = decode(key[1]);
        }
    }

    return assoc;
}
