I needed a random string for various purposes. For example, to provide a unique ID to HTML elements via JavaScript. The code below is a semi-random string generator function.

var guid = function() {
    var S4 = function() {
        return (((1 + Math.random()) * 0x10000)|0).toString(16).substring(1);
    };

    return (S4() + S4() + '-' + S4() + '-' + S4() + '-' + S4() + '-' + S4() + S4() + S4());
};
