1 通过new Object()直接创建对象

• 代码

var person =new Object();
// 给对象添加属性并赋值
person.name="张小明";
person.age=10;
person.foods=["苹果","橘子","香蕉","葡萄"];
// 给对象添加功能函数
person.eat= function (){
    console.log(this.age+"岁的"+this.name+"喜欢吃:")
    for(var i = 0;i<this.foods.length;i++){
        console.log(this.foods[i])
    } 
}
//获得对象属性值
console.log(person.name)
console.log(person.age)
//调用对象方法
person.eat();

• 效果
  

2 通过 { }形式创建对象

• 语法为 var person ={“属性名”:“属性值”,“属性名”,“属性值”,“函数名”:函数}
• 代码

var person ={
    "name":"张小明",
    "age":10,
    "foods":["苹果","香蕉","橘子","葡萄"],
    "eat":function (){
        console.log(this.age+"岁的"+this.name+"喜欢吃:")
        for(var i = 0;i<this.foods.length;i++){
            console.log(this.foods[i])
        } 
    }
}
//获得对象属性值
console.log(person.name)
console.log(person.age)
//调用对象方法
person.eat();
