string 用法小结

var a =["aaa","bbb","ccc"];

  var b=a.concat("ddd","eee");  

  alert(b.toString());             //aaa,bbb,ccc,ddd,eee

      

                

  var str="apple";

  var result=str.split("");

  alert(result);                   //a,p,p,l,e

     

  var arr=["aaa","bbb","ccc","ddd"];

  var b=arr.slice(1);

  var b1=arr.slice(1,3);

  alert(b.toString());               //bbb,ccc,ddd

  alert(b1.toString());             //bbb,ccc
