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>
