I'm currently in the process of creating a live search for my TV Shows web app. Everything is working fine. What I would like though is, if the filtered search is empty, to not display the <div>
My current implementation isn't working though...
Also I would like for it to display something like Please typ to search
if a user doesn't enter anything...
<div ng-controller="SearchController">
<div ng-show='shows.length > 0'>
<h3>Shows you've seen:</h3>
<hr>
<ul>
<li ng-repeat="show in shows | filter: searchbar">
{{ show.name }}
<img alt="{{ show.name }}" src="img/artwork/{{ show.image_name }}.png" style="width:50px;height:50px;">
</li>
</ul>
<hr>
</div>
<div ng-show='allshows.length > 0'>
<h3>All TV Shows:</h3>
<hr>
<ul>
<li ng-repeat="allshow in allshows | filter: searchbar">
{{ allshow.name }}
<img alt="{{ allshow.name }}" src="img/artwork/{{ allshow.image_name }}.png" style="width:50px;height:50px;">
</li>
</ul>
<hr>
</div>
</div>
==================== After some of the answers, this is what I created from them. Works great now!
<div ng-controller="SearchController">
<div ng-hide='searchbar'>
<h3>Please search something</h3>
</div>
<div ng-show='searchbar'>
<div ng-show="(filtered = (shows | filter:searchbar)).length > 0">
<h3>Shows you've seen:</h3>
<hr>
<ul>
<li ng-repeat="show in filtered">
{{ show.name }}
<img alt="{{ show.name }}" src="img/artwork/{{ show.image_name }}.png" style="width:50px;height:50px;">
</li>
</ul>
<hr>
</div>
<div ng-show="(allfiltered = (allshows | filter:searchbar)).length > 0">
<h3>All TV Shows:</h3>
<hr>
<ul>
<li ng-repeat="allshow in allfiltered">
{{ allshow.name }}
<img alt="{{ allshow.name }}" src="img/artwork/{{ allshow.image_name }}.png" style="width:50px;height:50px;">
</li>
</ul>
<hr>
</div>
</div>
</div>
You can do
<div ng-show="(shows|filter:searchbar).length > 0">
// content
</div>
But this has a performance issue ( using filter multiple times). Have a look at this too How to display length of filtered ng-repeat data
Please see working example http://jsbin.com/nusoc/1/edit
you can crate filterdShows
, filteredAllshows
in your repeater and use it in ng-show directive ie:
<div ng-show='filterdShows.length > 0'>
<h3>Shows you've seen:</h3>
<hr>
<ul>
<li ng-repeat="show in filterdShows = (shows | filter: searchbar)">
{{ show.name }}
<img alt="{{ show.name }}" src="img/artwork/{{ show.image_name }}.png" style="width:50px;height:50px;">
</li>
</ul>
<hr>
</div>
如果我正确理解了这个任务你应该用ng-show='shows.length > 0'
替换ng-show='shows.length > 0'
ng-show='searchbar'
