What is the best way to retrieve the scope of ng-repeat from another directive located on the same element as ng-repeat?

Is it possible to access a property from the ng-repeat scope in another directive within the same element as the ng-repeat directive? For instance, I would like to be able to use the child.class property in this scenario:

<div ng-class="{{ child.class }}" ng-repeat="child in parent.children">
    {{ child.name }}
</div>

You can view an example of this not working in this JSFiddle link.

If accessing properties between directives is not feasible, what alternative methods could be employed to apply a class to an element that utilizes ng-repeat? Is there a way to handle the ng-repeat function within a controller?

Answer №1

ng-class is a directive in AngularJS that takes an expression and evaluates it. If you modify the code to look like this:

ng-class="child.class"

it will function correctly! You can see a demo on JSFiddle here.

It's worth noting that you can also use something similar to this syntax:

ng-class="{'blue': true, 'red': false}"

The values of true or false can be replaced with other variables or functions, but only classes with a value of true will be added!

For more information, check out the ng-class documentation.
