How do I make FISHER-YATES work in a function to reuse it? [SOLVED]

I have found this tutorial:

construct.net/en/tutorials/implementing-fisher-yates-290

It works fine in itself. However, I cannot reuse it in a function. Can you make it work inside a function so that i could reuse it?

I tried passing the array with a array.uid, but it still does not work.

BTW, this is a javascript Fisher Yates, which works fine.

var array= [1,2,3];

function shuffleArray(array) {
 for (var i = array.length - 1; i > 0; i--) {
 var j = Math.floor(Math.random() * (i + 1));
 var temp = array[i];
 array[i] = array[j];
 array[j] = temp;
 }
 return array;
}
var x=shuffleArray(array);
alert(x);

I would expect something like this to work each time I click the button:

This is how it works fine in case you need it. This one is solved.
