ng-class and matching value inside array angularjs

Question

ng-class="{'active' : question.chosen == key}"

The above sets my class as active when question.chosen matches key. This means that $scope.question.chosen only has a single value.

In the even $scope.question.chosen has ["a","b","c"] how would I iterate through that with ng-class to match key?

You can try:

ng-class="{ 'active' : question.chosen.indexOf(key) >= 0 }"

You can have the ng-class object have keys as class names and values as functions that return booleans.

I set up a fiddle for you:

    <li ng-class="{'active': isActive('one')}">one</li>

Tell me if this helps :)
