Angular if ng-repeat多重过滤器为空

Question

假设我的ng-repeat中有多个过滤器，如下所示：

input.search(ng-model="filter", placeholder="Search...")

ul.list
  li(ng-if="things.length === 0") It looks like we don't have any things.
  li(ng-repeat="thing in things | orderBy:'name' | filter: search")
    span {{ thing.name }}

现在，如果我最初没有things，那么我会收到这样的消息。但是，如果我过滤掉没有结果的东西，它就不会显示我理解的消息。

我的问题是，如何在集合或过滤器没有结果的情况下实现多重过滤器ng-repeat并显示消息？

我弄乱this example无济于事。我的尝试：

thing in filteredThings = thing | orderBy: 'name' | filter: search

Answer 1

你很亲密，语法有点偏离：

(ng-repeat="thing in filteredThings = (things | orderBy:'name' | filter: search"))

li(ng-if="filteredThings.length === 0") It looks like we don't have any things.
