javascript 讓執行個體的方法都非同步執行

var C = function(){    this._methodList = [];}C.prototype.fire = function(obj){    var instance = this;    while(obj = this._methodList.shift()){        if(isFinite(obj.fn)){            var time = new Date;            instance.timeoutID = setTimeout(function(){                instance.fire();                instance._delayTime = new Date - time;            },obj.fn);            break;        }else{            this._result = obj.fn.apply(instance,obj.args)        }    }}C.prototype.wait = function(ms){    this._methodList.push({        fn:ms    });    return this;}C.prototype.abort = function(){    createTimeout(this.timeoutID);    this.fire();}C.extend = function(name,body){    if(typeof name === "object"){        for(var i in name){            if(name[i] !== void 0){                C.extend(i, name[i])            }        }    }else{        if(typeof body === "function"){            var method = C.prototype[name] = function(){                var obj = {                    args:arguments,                    fn:body                }                this._methodList.push(obj);                this.fire();                return this._result !== void 0 ? this : this;            }            method.toString = function(){                return body+"";            }        }else{            this.prototype[name] = body;        }    }    return this;}C.extend({    aaa:33,    attr:function(prop){        return this[prop];    },    getName:function(){        return this.name;    },    setName:function(name){        this.name = name;    }});var c = new C;console.log(c);c.attr(aaa);c.setName("司徒正美").wait(1000).getName();console.log(c.name);console.log(c.setName)
