可以说我在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,如果我过滤掉没有任何结果的东西,它不会显示该消息,据我所知。我的问题是,当集合或过滤器未产生结果时,如何实现多重过滤器
ng-repeat
并显示一条消息?我把this example弄乱了无济于事。我的尝试:
thing in filteredThings = thing | orderBy: 'name' | filter: search
最佳答案
您接近了,语法有些偏离:
(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.
关于javascript - 如果ng-repeat multi过滤器为空,则为 Angular ,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/28684735/
