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]);
  }
});
