/** 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);
