I am using Ionic3, and have:
<span class="char-left">{{REVIEW_MAX_LENGTH-ratingModel.review.length}} characters left</span>
I would like to conditionally change the class value when another value is populated, i.e when ratingForm.controls.review.length > 0 change the values to class="char-left-error".
I did look at ng-class, but cannot seem to get it to work.
Any help appreciated.
