UI Router - Check if a state exists

Question

I want something like this:

if ($state.get("^")) $state.go("^"); else $location.path('/');

But it apparently won't work (it always goes with $state.go even when there's no parent state). How to correctly do a check if an particular state exists?

Answer 1

you could use $state.href which will return null if the state does not exist. See http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state
