I have a few buttons that work like switchers. If you click one it becomes active and \"shuts down\" other buttons. I did this using jQuery but would like to use AngularJS.
You could have ng-click that can toggle selected flag, that could be use with ng-class to bind / unbind class.
ng-click
selected
ng-class
Markup
weak normal strong
Working Fiddle
Better way
You could easily do this by using ng-repeat which will reduce your line of code.
ng-repeat
$scope.strengths = ["weak","normal","strong"];
Code
{{strength}}
