You can extract the key/value pairs from the [location.search][1] property, this property has the part of the URL that follows the ? symbol, including the ? symbol.

function queryObj() {
    var result = {}, queryString = location.search.slice(1),
        re = /([^&=]+)=([^&]*)/g, m;
    
    while (m = re.exec(queryString)) {
        result[decodeURIComponent(m[1])] = decodeURIComponent(m[2]);
    }
    
    return result;
}

// Usage:
var myParam = queryObj()["myParam"];

No need to use regex:

function queryObj() {
    var result = {}, keyValuePairs = location.search.slice(1).split('&');

    keyValuePairs.forEach(function(keyValuePair) {
        keyValuePair = keyValuePair.split('=');
        result[keyValuePair[0]] = keyValuePair[1] || '';
    });
    
    return result;
}

For IE8- support include this tiny Array.forEach* polyfill:

if ( !Array.prototype.forEach ) {
    Array.prototype.forEach = function(fn, scope) {
        for(var i = 0, len = this.length; i < len; ++i) {
            fn.call(scope, this[i], i, this);
        }
    }
}
