I'm using AngularUI's routing and I'd like to do a ng-class="{active: current.state}" but I'm unsure how to exactly detect the current state in a directive like this.

Update:

This answer was for a much older release of Ui-Router. For the more recent releases (0.2.5+), please use the helper directive ui-sref-active. Details here.

Original Answer:

Include the $state service in your controller. You can assign this service to a property on your scope.

An example:

$scope.$state = $state;

Then to get the current state in your templates:

$state.current.name

To check if a state is current active:

$state.includes('stateName');

This method returns true if the state is included, even if it's part of a nested state. If you were at a nested state, user.details, and you checked for $state.includes('user'), it'd return true.

In your class example, you'd do something like this:

ng-class="{active: $state.includes('stateName')}"
