Sometimes I wish addEventListener in javascript would return an object so that you can cancel the event without having to name the function.

addEvent

EventTarget.prototype.addEvent = function () {
    var args = [].slice.call(arguments);
    var remove = (function () {
        this.removeEventListener.apply(this, args);
    }).bind(this);
    this.addEventListener.apply(this, arguments);
    return remove;
};
