javascript爲對象添加自定義方法的幾種方式

1.

 var student = new Object();
     student.name = "xiao ming";
     student.age = 20;
     student.getName = function () {
         alert(this.name);
     }

2.

  var student = {
        name: "xiao hong",
        age: 18,
        getName: function () {
            alert(this.name);
        }
    };

3.工廠模式

    function studentFactory(name,age) {
         var student = new Object();
         student.name = name;
         student.age = age;
         student.sayName = function () {
             alert(this.name);
         }
         return student;
     }
     var p1 = studentFactory("ming", 20);
     var p2 = studentFactory("hong", 18);
