JavaScript实现数组随机排序的方法

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;};

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]);  }});
