Interface Ng2Component

This callback is used to inform a view that it is about to be exited, due to a new Transition. The callback can ask for user confirmation, and cancel or alter the new Transition. The callback should return a value, or a promise for a value. If a promise is returned, the new Transition waits until the promise settles.

Called when:

• The view is still active
• A new Transition is about to run
• The new Transition will exit the view's state

Called with:

• This callback is injected in the new Transition's context

Relevant return Values:

• false: The transition is cancelled.
• A rejected promise: The transition is cancelled.
• TargetState: The transition is redirected to the new target state.
• Anything else: the transition will continue normally (the state and view will be deactivated)

This callback can be used to respond to changing parameter values in the current state, or in parent/child states. This callback is especially handy when using dynamic parameters (ParamDeclaration.dynamic)

Called when:

• The view is still active
• A new transition has completed successfully
• The state for the view (controller) was not reloaded
• At least one parameter value was changed

Called with:

example

:

angular.module('foo').controller('FancyCtrl', function() {
  this.uiOnParamsChanged = function(newParams) {
    console.log("new params: ", newParams);
  }
});
