javascript生成对象的三种方法

/** js生成对象的三种方法*/

// 1.通过new Object,然后添加属性  示例如下:

var people1 = new Object();
people1.name = 'xiaohailong01';
people1.age = 31;

alert("name:" + people1.name + ", age:" + people1.age);

// 2.直接接收json数据生成

var people2 = {
    name : 'xiaohailong02',
    age : 32
};

alert("name:" + people2.name + ", age:" + people2.age);

// 3.通过function方法(模拟类)

function People (name, age) {
    this.name = name;
    this.age = age;
}

var people3 = new People('xiaohailong03', 33);
alert('name:' + people3.name + ', age:' + people3.age);
