Additional arguments to the event handler are provided:

• toState: the Transition Target state
• toParams: the Transition Target Params
• fromState: the state the transition is coming from
• fromParams: the parameters from the state the transition is coming from
• options: any Transition Options
• $transition$: the Transition that was cancelled

It's important to note that if you have any errors in your resolve functions (javascript errors, non-existent services, etc) they will not throw traditionally. You must listen for this $stateChangeError event to catch ALL errors.

Additional arguments to the event handler are provided:

• toState: the Transition Target state
• toParams: the Transition Target Params
• fromState: the state the transition is coming from
• fromParams: the parameters from the state the transition is coming from
• error: The reason the transition errored.
• options: any Transition Options
• $transition$: the Transition that errored

deprecated

use TransitionService.onStart and Transition.promise, or Transition.onError

You can use event.preventDefault() to prevent the transition from happening and then the transition promise will be rejected with a 'transition prevented' value.

Additional arguments to the event handler are provided:

• toState: the Transition Target state
• toParams: the Transition Target Params
• fromState: the state the transition is coming from
• fromParams: the parameters from the state the transition is coming from
• options: any Transition Options
• $transition$: the Transition

example

$rootScope.$on('$stateChangeStart', function(event, transition) {
  event.preventDefault();
  // transitionTo() promise will be rejected with
  // a 'transition prevented' error
})

deprecated

use TransitionService.onStart

Additional arguments to the event handler are provided:

• toState: the Transition Target state
• toParams: the Transition Target Params
• fromState: the state the transition is coming from
• fromParams: the parameters from the state the transition is coming from
• options: any Transition Options
• $transition$: the Transition that just succeeded

deprecated

use TransitionService.onStart and Transition.promise, or Transition.onSuccess

The event is broadcast allowing any handlers a single chance to deal with the error (usually by lazy-loading the unfound state). A TargetState object is passed to the listener handler, you can see its properties in the example. You can use event.preventDefault() to abort the transition and the promise returned from transitionTo() will be rejected with a 'transition aborted' error.

Additional arguments to the event handler are provided:

• unfoundState Unfound State information. Contains: to, toParams, options properties.
• fromState: the state the transition is coming from
• fromParams: the parameters from the state the transition is coming from
• options: any Transition Options

example

// somewhere, assume lazy.state has not been defined
$state.go("lazy.state", { a: 1, b: 2 }, { inherit: false });

// somewhere else
$scope.$on('$stateNotFound', function(event, transition) {
function(event, unfoundState, fromState, fromParams){
    console.log(unfoundState.to); // "lazy.state"
    console.log(unfoundState.toParams); // {a:1, b:2}
    console.log(unfoundState.options); // {inherit:false} + default options
});

deprecated

use StateProvider.onInvalid // TODO: Move to [[StateService.onInvalid]]
