AngularJS ng-repeat handle empty list case

Question

I thought this would be a very common thing, but I couldn\'t find how to handle it in AngularJS. Let\'s say I have a list of events and want to output them with AngularJS, t

Answer 1

<ul>
    <li ng-repeat="item in items | filter:keyword as filteredItems">
        ...
    </li>
    <li ng-if="filteredItems.length===0">
        No items found
    </li>
</ul>

This is similar to @Konrad 'ktoso' Malawski but slightly easier to remember.

Tested with Angular 1.4

Answer 2

You might want to check out the angular-ui directive ui-if if you just want to remove the ul from the DOM when the list is empty:

<ul ui-if="!!events.length">
    <li ng-repeat="event in events">{{event.title}}</li>
</ul>

Answer 3

You can use ngShow.

<li ng-show="!events.length">No events</li>

See example.

Or you can use ngHide

<li ng-hide="events.length">No events</li>

See example.

For object you can test Object.keys.

Answer 4

With the newer versions of angularjs the correct answer to this question is to use ng-if:

<ul>
  <li ng-if="list.length === 0">( No items in this list yet! )</li>
  <li ng-repeat="item in list">{{ item }}</li>
</ul>

This solution will not flicker when the list is about to download either because the list has to be defined and with a length of 0 for the message to display.

Tip: You can also show a loading text or spinner:

  <li ng-if="!list">( Loading... )</li>

Answer 5

you can use ng-if because this is not render in html page and you dont see your html tag in inspect...

<ul ng-repeat="item in items" ng-if="items.length > 0">
    <li>{{item}}<li>
</ul>
<div class="alert alert-info">there is no items!</div>

Answer 6

i usually use ng-show

<li ng-show="variable.length"></li>

where variable you define for example

<div class="list-group-item" ng-repeat="product in store.products">
   <li ng-show="product.length">show something</li>
</div>
