JS——属性绑定

1、普通形式

<script>
    var stu = new Object();
    stu.name = "ww";
    console.log(stu);//{name: "ww"}
</script>

2、特殊形式：数字或者变量

<script>
    var stu = new Object();
    stu.name = "ww";
    var aaa = "age";
    stu[aaa] = 19;
    stu[0] = "男";
    console.log(stu);//{0: "男", name: "ww", age: 19}
</script>
