loop.js是一个单例模式的js类：
//一开始就用new 无名类的方式创建。这样就实现了单例的功能。
var loop = new (function(){
// 外部公共函数
// 无限循环的操作
this.setloop = function(fn){Infinite_loop.setLoopFn(fn);} // 参数 1 参数类型 function
this.deleteloop = function(fn){Infinite_loop.deleteLoopFn(fn);} // 参数 1 参数类型 function
this.stoploop = function(){Infinite_loop.stopLoop();}
// 单次循环的操作
this.setloopOne = function(fn){one_loop.setLoopOneFn(fn);} // 参数 1 参数类型 function
this.stoploopOne = function(){one_loop.stopLoopOne();}
// 下面是两个私有的单例模式成员
// 无限循环执行的List对象
var Infinite_loop = new (function(){
this.loop_stop = true;
this.loop_action = new Array();
this.loop_actionID = 0;
var opp = this;
this.setLoopFn = function(fn){
if(typeof(fn)!="function"){
throw new Error("window.loop.setloop's argment is not a function!"); return;
}
for(var i=0;i if(this.loop_action[i] == fn){

其实大家可以再深入思考一下，
例如模拟一个简单工厂类的东西。
