JavaScript常用"类"构建方式
带有构造函数(原型方式)的"类":
function Student(name,gender,age){ this.name = name; this.gender = gender; this.age = age; this.hobby = new Array();}Student.prototype.showHobbies = function(){ var hobbies = ""; for(var arg in this.hobby){ hobbies += (this.hobby[arg] + " "); } alert(this.name + "'s hobbies are "+hobbies); hobbies = null;}var stu1 = new Student("Bob","male","24");var stu2 = new Student("Tina","female","23");stu1.hobby.push("basketball");stu1.hobby.push("football");stu2.hobby.push("music");stu2.hobby.push("dancing");stu2.hobby.push("reading");stu1.showHobbies();stu2.showHobbies();function Student(name,gender,age){ this.name = name; this.gender = gender; this.age = age; this.hobby = new Array(); if(typeof Student._initalized == "undefined") { Student.prototype.showHobbies = function(){ var hobbies = ""; for(var arg in this.hobby){ hobbies += (this.hobby[arg] + " "); } alert(this.name + "'s hobbies are "+hobbies); hobbies = null; } } Sutdent._initalized = ture;}
