【jQuery】 js 对象

【jQuery】 js 对象

 一.  创建对象的三种方式

<script>
    var v1 = new Object();
    v1.name = "name1";
    v1.age = 19;
    v1.sex = 1;
    alert(v1.name);

    function obj(name, age, sex) {
        this.name = name;
        this.age = age;
        this.sex = sex;
    }
    var v2 = new obj("name2", 18, 1);
    alert(v2.name);

    v3 = { name: "name3", age: 20, sex: 1 };
    alert(v3.name);
</script>

 二. 数组

    var stus = new Array();
    stus[0] = "stu1";
    stus[1] = "stu2";
    stus[2] = "stu3";
    for (var i = 0; i < stus.length; i++) {
        alert(stus[i]);
    }

    var stus2 = new Array("stu1", "stu2", "stu3");
    for (var i = 0; i < stus2.length; i++) {
        alert(stus2[i]);
    }
