			JavaScript能够实现的面向对象的特征有：
			·公有属性(public field)
			·公有方法(public Method)
			·私有属性(private field)
			·私有方法(private field)
			·方法重载(method overload)
			·构造函数(constructor)
			·事件(event)
			·单一继承(single inherit)
			·子类重写父类的属性或方法(override)
			·静态属性或方法(static member)
			function AClass(){
				this.property = 1;
				this.method = function(){
					alert("method");
			// 1 在原型上添加属性和方法
			AClass.prototype.property2 = 2;
			AClass.prototype.method2 = function(){
				alert("prototype method!");
			var a = new AClass();
			// 2 在对象上添加属性和方法
			a.property3 = 3;
			a.method3 = function(){
				alert("instance method!");
			// 3 在对象上改变属性和方法。（和普遍的面向对象的概念不同）
			a.property = 2;
			a.method = function(){
				alert("method2");
			alert(a.property);
			//alert(a.property2);
			//alert(a.property3);
			a.method();
			//a.method2();
			//a.method3();
			// 4 静态成员，静态方法
			AClass.staticProperty = 5;
			AClass.staticMethod = function(){
				alert("static method!");
			alert(AClass.staticProperty);
			AClass.staticMethod();*/
