Reversing words in a string

Question

Hello, does anybody know how can I sort words in string using javascript, jquery.

For example I have this:

var words = "1 3 2"

Now I want to reverse it to this:

var words = "2 3 1"

Thanks

Answer 1

Here's the basic idea, no need to import jQuery:

var words = "1 3 2"

var i=words.length;
i=i-1;

var reversedwords=""; 
for (var x = i; x >=0; x--)
{
    reversedwords +=(words.charAt(x));
}

alert(reversedwords) // "2 3 1"

This would also work in reversing the string "string" to "gnirts"

Answer 2

Assuming you are reversing (I'm sure this'll still help if you're not).

var original = '1 3 2';
var reversed = original.split(' ').reverse().join(' ');
