模块化编程怎么样

[汪小哥]

var HelloWorld = function(els){
            var Component = function(els){
                this.els = els;
            };
            Component.prototype = {
                initialize : function(){
                    alert("HelloWorld");
                }
            }
            return new Component(els);
        }
        var comp = new HelloWorld("body");
        comp.initialize();
