js在构造函数中使用this

<script>

// 自定义构造函数

function User(name, age, address) {

this.name = name;

this.age = age;

this.address = address;

this.addShopcart = function(product) {

console.log(this.name + '将' + product + '加入购物车！');

}

}

// 实例化构造函数 创建对象

var u1 = new User('高小乐', 19, '上海');

console.log(u1);

console.log('');

var u2 = new User('曹操', 89, '北京');

console.log(u2);

</script>
