Javascript创建对象的常用方法

直奔主题，JS创建对象的方法：

   //1.字面量创建对象

    //    var student={name:"张三",school:"洛阳师院"};

    //    document.write("姓名："+student.name+"
"+"来自："+student.school)

    //2.构造函数创建对象及输出对象属性

    //    function Student(name,school){

    //        this.name=name;

    //        this.school=school;

    //        this.outFun=function(){

    //            document.write("姓名："+this.name+"
"+"来自："+this.school)

    //        }

    //    }

    //

    //    c

    //    student1.outFun();

   //3.new运算符创建对象，循环输出

    //    var student=new Object();

    //    var lesson=new Object();

    //    student.name="王五";

    //    student["school"]="河南大学";

    //    lesson["0"]="Java基础";

    //    lesson["1"]="HTML";

    //    lesson["2"]="CSS";

    //    lesson["3"]="JavaScript";

    //    document.write("姓名："+student.name+"
"+"来自："+student.school+"
");

    //    document.write("学习的课程有："+"
");

    //    for(var i in lesson){

    //        document.write(lesson[i]+"
");

    //    }

   //4.通过prototype向对象中添加属性和方法

         //    function Student(name, school) {

         //        this.name = name;

         //        this.school = school;

         //    }

         //

         //    Student.prototype.lesson="HTML5";

         //    var student1=new Student("赵六","郑州大学");

         //    document.write(student1.lesson);
