JS中通过数组的方式操作字符串 数组是个好东西 ....

题目:使用JS将 var str="what are you nong sha lei",通过您的方法转换为"What Are You Nong Sha Lei";

1　　function getCap(string){
      var arr=string.split(" ");//将字符串用" "(一个空格)拆为数组
      for(var i=0;i<arr.length;i++){
        arr[i]=arr[i].charAt(0).toUpperCase()+arr[i].slice(1);
      }
      return arr.join(" ");//数组转为字符串  每项用" " 隔开
    }
   var str="what are you nong sha lei";
   console.log(getCap(str));
