JavaScript: array random sorting method, javascript Array

This example describes how to implement random array sorting in JavaScript. Share it with you for your reference. The specific implementation method is 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 ;};

Usage:

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 result:
