Apply class conditionally angular

Question

I am trying to apply class conditionally through ng-class but its not working

ng-class="{'margin-watch':progress <= '0','margin-continue-watch':progress > '0' }"

Answer 1

Try this

ng-class="{'margin-watch': (progress <= 0), 'margin-continue-watch': (progress > 0) }

Answer 2

Unless your condition requires you to compare progress to the character '0', you should remove the quotes around the 0. That should fix your expressions! For readability I suggest you apply the () as Yasser does in his answer, but it should work without aswell.
