从数据库查询出来的按EXCHANGE_INTEGRAL字段升序(异步分页排序)
[394483] => Array
(
[EXCHANGE_INTEGRAL] => 10
[salePrice] => 39.50
[skuId] => 394483
[title] => 吉来 椴树蜂蜜500克/瓶
)
[389614] => Array
(
[EXCHANGE_INTEGRAL] => 12
[salePrice] => 9.80
[skuId] => 389614
[title] => 悠果乐 果汁软糖 香橙味 105g/盒
)
[403430] => Array
(
[EXCHANGE_INTEGRAL] => 16
[salePrice] => 300.00
[skuId] => 403430
[title] => 万家乐电饭煲
)
结果ajax请求过来的数据顺序却按skuId排序了389614，394483，403430
解决办法：
重组数据结构，不拿skuId作为key，让其默认排序，这样就不会影响排序了
[0] => Array
(
[EXCHANGE_INTEGRAL] => 10
[salePrice] => 39.50
[skuId] => 394483
[title] => 吉来 椴树蜂蜜500克/瓶
)
[1] => Array
(
[EXCHANGE_INTEGRAL] => 12
[salePrice] => 9.80
[skuId] => 389614
[title] => 悠果乐 果汁软糖 香橙味 105g/盒
)
[2] => Array
(
[EXCHANGE_INTEGRAL] => 16
[salePrice] => 300.00
[skuId] => 403430
[title] => 万家乐电饭煲
)
