**简介**：JavaScript中的自定义对象，相当于Java中的类。

#### 自定义对象 ####

格式：

var 对象名称 = {
        
        属性名称1:属性值1,
        属性名称2:属性值2,
        ...,
        函数名称:function (形参列表){
        },
    	...
    };

调用属性的格式：

对象名.属性名

调用函数的格式：

对象名.函数名()

演示代码：

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        
    <script>
        var person = {
        
            name : "zhangsan",
            age : 33,
            eat: function (){
        
                console.log("干饭~");
            }
        };
        console.log(person.name);  //zhangsan
        console.log(person.age); //23
    
        person.eat();  //干饭~
    </script>
    </body>
    </html>

**运行结果**
