var h = new Object(); // or just {}
h['one'] = 1;
h['two'] = 2;
h['three'] = 3;

// show the values stored
for (var k in h) {
    // use hasOwnProperty to filter out keys from the Object.prototype
    if (h.hasOwnProperty(k)) {
        alert('key is: ' + k + ', value is: ' + h[k]);
    }
}

String.prototype.hashCode = function() {
    var hash = 0;
    if (this.length == 0) {
        return hash;
    }
    for (var i = 0; i < this.length; i++) {
        var char = this.charCodeAt(i);
        hash = ((hash<<5)-hash)+char;
        hash = hash & hash; // Convert to 32bit integer
    }
    return hash;

    var i, l,

    for (i = 0, l = str.length; i < l; i++) {
        hval ^= str.charCodeAt(i);
        hval += (hval << 1) + (hval << 4) + (hval << 7) + (hval << 8) + (hval << 24);
    }
    if( asString ){
        // Convert to 8 digit hex string
        return ("0000000" + (hval >>> 0).toString(16)).substr(-8);
    }
    return hval >>> 0;
