JavaScript多继承的实现详解编程语言

function BaseClass1(){ 
		this.age=10; 
		this.sex='male'; 
	} 
	BaseClass1.prototype.run = function(){ 
		console.log("run"); 
	} 
 
	function BaseClass2(){ 
		this.prop1='prop1'; 
		this.prop2='prop2'; 
	} 
	BaseClass2.prototype.walk = function(){ 
		console.log("walk"); 
	} 
 
	function ChildClass(country,hobby){ 
		this.country=country; 
		this.hobby=hobby; 
		//实例属性继承 
		BaseClass1.call(this); 
		BaseClass2.call(this); 
	} 
 
	//原型链继承 
	for(var prop in BaseClass1.prototype){ 
		ChildClass.prototype[prop] = BaseClass1.prototype[prop]; 
	} 
	for(var prop in BaseClass2.prototype){ 
		ChildClass.prototype[prop] = BaseClass2.prototype[prop]; 
	} 
	 
	// ChildClass.prototype.constructor=ChildClass; 
	var childInstance = new ChildClass('China','ball'); 
	childInstance.run(); 
	childInstance.walk(); 
	console.log(childInstance.prop1); 
	console.log(childInstance.age);
