1、构造函数模式---》alert的结果为false
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> function Person(name,age,job){ this.name = name; this.age = age; this.job = job; this.showname = function(){ alert(this.name); } this.showage = function(){ alert(this.age); } this.showjob = function(){ alert(this.job); } } var tom = new Person(‘tom‘,18,‘程序员‘); var jack = new Person(‘jack‘,19,‘销售‘); alert(tom.showjob == jack.showjob); //结果为False </script> </head> <body> </body> </html>
2.原型模式---->alert结果为true
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script> function Person(name,age,job){ this.name = name; this.age = age; this.job = job; } Person.prototype.showname = function(){ alert(‘我的名字叫‘+this.name); } Person.prototype.showage = function(){ alert(this.age); } Person.prototype.showjob = function(){ alert(this.job); } var tom = new Person(‘tom‘,18,‘程序员‘); var jack = new Person(‘jack‘,19,‘销售‘); alert(tom.showjob == jack.showjob);//结果为True </script> </head> <body> </body> </html>
javascript中面向对象的两种构建方式（构造函数）和（原型模式的区别）
