How to compare the same data in two strings

This time I will show you how to compare the same data in two strings, and what are the precautions when comparing the same data in two strings , the following is a practical case, let’s take a look.

There are two strings:

$a = "5,8,0";
$b = "8,0,5";

How to quickly compare the numbers contained in these two strings are the same, the delimiters are the same, but the order of the numbers is different, the length of the two strings is the same

js code:

Method 1:

var s1 = "5,0,8";
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");
}

Method 2:

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;
  }
 }
}
if (isSame) {
 alert("数字相同");
} else {
 alert("数字不同");
}
