call和apply

function.apply(thisObj,[“参数一”，"参数二"......]  <script type="text/javascript">

      function People(name,skill){
          this.name=name;
          this.skill=skill;
          this.paly=function(){
              alert( this.name+"使出了"+this.skill)
          }
      }
      var people1=new People("欧阳修","蛤蟆功");
      var person=new Object();//重新创建了一个对象
      People.apply(person ,["孙悟空","七十二变"]);//
这步改变了this的作用域，通俗的理解就是person对象冒充了People对象，
然后使用了People对象中的属性和方法
      people1.paly();
      person.paly()

  </script>
//弹出结果：

function.call(thisObj[, arg1[, arg2[, [,...argN]]]]);  <script type="text/javascript">
了解：

  	function People(name,skill){
  		this.name=name;
  		this.skill=skill;
  		this.paly=function(){
  			alert( this.name+"使出了"+this.skill)
  		}
  	}
  	var people1=new People("小鱼儿","吐泡泡");
   	var person=new Object();
        People.call(person ,"啄木鸟","捉虫子");
 	people1.paly();
 	person.paly()

  </script>
