AngularJs中按日期过滤器降序排列 [英] Descending order by date filter in AngularJs

问题描述

所以这本书来自rest api，并且附上了很多读者.我想获取最近"的读者.

created_at 字段具有将用户标识为最近用户的值.但是上面的代码给了我最老的读者.那么顺序需要颠倒吗?有没有办法按降序排序?

解决方案

根据 文档 你可以使用 reverse 参数.

filter:orderBy(array, expression[, reverse]);

将过滤器更改为:

orderBy: 'created_at':true

<div class="recent" ng-repeat="reader in
    (filteredItems = (book.reader | orderBy: 'created_at' | limitTo: 1))">
</div>

So the book comes from rest api and it has many readers attached. I want to get the 'recent' reader.

The created_at field has the value which identifies the user as recent. But the above code gives me the oldest reader. So the order needs to be inversed? Is there some way to have the sorting in descending order?

解决方案

According to documentation you can use the reverse argument.

filter:orderBy(array, expression[, reverse]);

Change your filter to:

orderBy: 'created_at':true
