Extending Mootools

Mootools lacks an easy way of checking events on objects. This is a Mootools extension to do so.

/**

Native.implement([Element, Window, Document], {
    hasEvent: function(type) {
        var events = this.retrieve('events', {});
        if (events && events[type]){
            return true;
        } else {
            return false;
        }
    },
    getEvents: function() {
        var events = this.retrieve('events', {});
        if (events) {
            return events;
        } else {
            return null;
        }
    }
});
