1、普通数组排序：
①Array.sort(); //升序
[5, 4, 3, 2, 1].sort(); ==> [1,2,3,4,5]
②Array.sort(function(a,b){return a-b;}) //升序：a-b；降序：b-a;
[5, 4, 3, 2, 1].sort(function(a,b){return a-b;}) ==>[1,2,3,4,5]
[5, 4, 3, 2, 1].sort(function(a,b){return b-a;}) ==>[5, 4, 3, 2, 1]
3、对象数组排序：
Array.sort(function(a,b){
return a.Key>b.Key?1:-1;
})
