JavaScript 面向对象基础简单示例

<script>
function Foo(n){
  this.name = n;
  this.sayName = function(){
    console.log(this.name)
  }
}
var obj1 = new Foo('jb51');
obj1.name
obj1.sayName()
var obj2 = new Foo('狼蚁SEO');
obj2.name
obj2.sayName ()
</script>

<script>
function Foo(n){
  this.name = n;
}
// Foo的原型
Foo.prototype = {
  'sayName': function(){
  console.log(this.name)
  }
}
var obj1 = new Foo('欢迎访问');
obj1.name
obj1.sayName()
var obj2 = new Foo('.jb51.');
obj2.name
obj2.sayName()
</script>
