Check if value in array in angular template?

by

You can use indexOf() to test whether a value is in an array and then use it inside your ngClass like this (to conditionally add “newclass”):

<div ng-class="{'newclass':([1,2,5].indexOf(2) > -1)}">Yay</div>

Or more likely you’ll want to test against an array on your scope:

<div ng-class="{'newclass':(tarray.indexOf(1) > -1)}">Yay</div>

Assuming, for instance, you have declared tarray in your controller:

$scope.tarray=[1,2,5];

As far as a template engine, it’s built in to Angular. So there’s not really something separate to search for. But here’s the top level template docs and there’s some good video tutorials here that cover templates (for instance the first one is on data binding) as well as much more.
