jQuery: randomize words in a string?

Question

I'm trying to randomize the words in a string using jquery but my code doesn't return anything.

This is what I have so far:

function makerand() {


  var text = "";
  var possible = "david, sarah, michelle, pedro";

   text += possible.charAt(Math.floor(Math.random() * possible.length));

  return text;

  alert(text);
}

html:

<button onclick="makerand()">click me</button>

what I need to do is to randomize that string like so for example:

sarah, pedro, michelle, david

Could someone please advise on this?

Split the string into an array like so:

var items = possible.split(", ");

Then shuffle the array like so: How to randomize (shuffle) a JavaScript array?

Then rejoin the elements:

possible.join(", ")

Split the String by comma. You get an array back and then sort the array by giving random.

var possible = "david, sarah, michelle, pedro";

var result = possible.split(", ").sort(function() {
    return 0.4 - Math.random()
}).join(", ");

console.log(result)

This is changing order to specific order that @DavidHope incorectly said *randomize*. – Mohammad Aug 05 '17 at 16:42
@Mohammad OP himself accepted that , this is what OP need. – Suresh Atta Aug 05 '17 at 16:46
I know this. I mean @DavidHope does't write his need in question exactly. – Mohammad Aug 05 '17 at 16:50
