javascript - 如果 ng-repeat multi 过滤器为空，则 Angular

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，如果我过滤了没有结果的东西，它就不会显示消息，我理解这一点。

我的问题是，如何实现多过滤器 ng-repeat 并在收集或过滤器没有结果时显示消息？

我在搞乱 this example无济于事。我的尝试:

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

你很接近，语法有点不对:

(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.
