js原型链继承及调用父类方法

function Rect(config){}
Rect.prototype.area = function(){ alert("我是父方法"); } function myRect(config){ arguments.callee.prototype.constructor.prototype.area(); //子类里调用父方法area arguments.callee.prototype.area();//子类里调用重载方法area } myRect.prototype = new Rect(); myRect.prototype.area = function(){ alert("我是重载方法"); } var rectObj = new myRect(); rectObj.constructor.prototype.area();//子类实例调用父类方法area rectObj.area();//子类实例调用子类方法area
