call 与 apply的区别

 

 

 

 function calc(base,bonus1,bonus2){
    console.log(
      this.ename+"的总工资是"+
      (base+bonus1+bonus2));
  }
  var lilei={ename:"Li Lei"};
  var hmm={ename:"Han Meimei"};
  //lilei临时强行借用函数calc
  calc.call(lilei,10000,1000,2000);    //参数不是数组
  calc.apply(hmm,[4000,3000,5000]);   // 参数为数组

  //lilei买一个新的属于自己的计算器:
  var lileiCalc=calc.bind(lilei,10000);
                        // this  base
  //创建一个和calc一模一样的新函数，并永久绑定this为lilei
  lileiCalc(1000,2000);
         //bonus1 bonus2
  //lileiCalc.call(hmm,3000,5000);

运行结果:
