//Event is a simple class for implementing the Observer pattern:
function Event(sender) {
    this._sender = sender;
    this._listeners = [];
}

Event.prototype = {
    attach : function (listener) {//push the callback function into _listeners[];
        this._listeners.push(listener);
    },
    notify : function (args) {//pop all the callback functions and execute the functions with same args?
        var index;

        for (index = 0; index < this._listeners.length; index += 1) {
            this._listeners[index](this._sender, args);//auto pass sender and args into callback function, so the default form of callback function is function(sender,args){}
        }
    }
