The example in this article describes how JavaScript uses functions to implement objects. Share it with everyone for your reference. The specific implementation method is as follows:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>利用函数实现对象(重要)</title>
<script type="text/javascript">
  function Person(name, age) {
    //定义属性,同时初始化
    this.name = name;
    this.age = age;
    //定义方法
    this.ShowInfo = function () {
      alert("name:" + this.name + "--age:" + this.age);
    }
  }
  var ZhangShan = new Person("张三", 30);
  alert("Name:" + ZhangShan["name"] + ",Age:" + ZhangShan.age);
  //注意第一个属性用的是中括号括起来的，可以动态传递属性名称
  ZhangShan.ShowInfo();
</script>
</head>
<body>
</body>
</html>
