var s2 = "8,0,5";
if(s1.split(",").sort().join(",") == s2.split(",").sort().join(",")) {
 alert("数字相同");
}else{
 alert("数字不同");
}

var s1 = "5,0,8";
var s2 = "8,0,5";
var a1 = s1.split(",");
var a2 = s2.split(",");
var isSame = false;
if (a1.length == a2.length) {
 isSame = true;
 var length = a2.length;
 for (var i = 0; i < length; i++) {
  if (a1.indexOf(a2[i]) < 0) {
   isSame = false;
   break;
