You can accomplish this with a slightly different syntax   ng-class    approved   selectedForApproval indexOf jobSet      -1     Plnkr

Somewhere in your initialisation put this code   Array prototype contains   function contains obj        for  var i   0  i  lt  this length  i              if  this i      obj                return true                      return false       Then  you can use it this way    lt li ng-class   approved  selectedForApproval contains jobSet    gt  lt  li gt

You shouldn t overload the templates with complex logic  it s a bad practice  Remember to always keep it simple   The better approach would be to extract this logic into reusable function on your  rootScope    run function   rootScope       rootScope inArray   function  item  array        return  -1     array indexOf item              Then  use it in your template    lt li ng-class   approved  inArray jobSet  selectedForApproval    gt  lt  li gt    I think everyone will agree that this example is much more readable and maintainable
