A method of implementing array random ordering by JavaScript _javascript techniques

In this paper, we describe the method of implementing the random ordering of the array by JavaScript. Share to everyone for your reference. The implementation methods are as follows:

function Shuffle (o) {
  for (Var j, x, i = o.length; i; j = parseint (Math.random () * i), x = O[--i], o[i] = O[j], o[j] = x);
  return o;
};

How to use:

var testarray = [1,2,3,4,5];
Shuffle (Testarray);
JQuery to dump out new values to element with ID of ' dump '
$ (function () {for
  (var i=0;i<testarray.length;i+ +) {
   $ ("#dump"). Append (Testarray[i]);

Output results:
