js 实现多事件绑定，既适i用于自定义事件，也可以适用于系统事件，而且支持参数传递 源代码:

function createFunction(obj,func){

	var args=[];

	if(!obj){ obj=window;}

	for(var i=2;i<arguments.length;i++){

		args.push(arguments[i])

	}

	return function(){

		obj[func].apply(obj,args);

	}

}



function eventDemo(){

	

}

eventDemo.prototype={

	show:function(){

		if(this.events){

			for(var i=0;i<this.events.length;i++){

				this.events[i]();

			}

		}

	},

	attachEvents:function(eventHandler){

		if (!this.events) this.events=[];

		this.events.push(eventHandler);

	}

	

}

var obj=new eventDemo();

var userName1="jake1";

var userName2="jake2";

function objOnShow1(userName){

	alert(userName+" execute a onShow event");

	

}

function objOnShow2(userName){

	alert(userName+" execute a onShow event");

	

}

obj.attachEvents(createFunction(null,"objOnShow1",userName1));

obj.attachEvents(createFunction(null,"objOnShow2",userName2));

obj.show();
