问题描述

我有一个带有 ID 的帖子列表，例如1,2,3,4,5,6,7,8,9,10,11,12(json格式)id 是字符串类型.但我想按照它的数字顺序排序正常 orderBy:'fiche.id' 列表显示如下.1,10,11,12,2,3,4,5,6,7,8,9

I have a list of post with ids like 1,2,3,4,5,6,7,8,9,10,11,12 (json format) The ids are of type String. But I would like to order it according to its numerical order Normal orderBy:'fiche.id' the list is displayed as below. 1,10,11,12,2,3,4,5,6,7,8,9

我希望输出是有序的 - 1,2,3,4,5,6,7,8,9,10,11,12

I would like the output to be of order - 1,2,3,4,5,6,7,8,9,10,11,12

推荐答案

我猜你的 id 是字符串.一个简单的解决方案是使用否.操作里面order by.因此，不要使用 orderBy:'id' 而是使用 orderBy:'id*1' 这会将 id 视为 no.并按照数字顺序排序.

I guess your ids are strings. A simple solution would be use a no. operation inside order by. So instead ofr orderBy:'id' just use orderBy:'id*1' this will consider the id as no. and sort it according to the numerical order.

这就是你所需要的 - <div ng-repeat="fiche in fiches | orderBy:'id*1'">{{fiche.id}}</div>

This is all you need - <div ng-repeat="fiche in fiches | orderBy:'id*1'">{{fiche.id}}</div>
