AngularJS Question

Angularjs ui-router, How to get preload resolve value when $stateChangeSuccess trigger?

$stateProvider.state('home', {
url: '/',
resolve: {
person: function() {
return 'good'
}
}


like above state config, how can I get the 'person' value in $stateChangeSuccess callback function ?

$rootScope.$on('$stateChangeSuccess',
function(event, toState, toParams, fromState, fromParams) {
// I want get the 'person' value in this function, what should I do?
});

Answer

We had the same problem. We solved it by relying on some internal implementation details of ui-router; this does mean that it might break in a future version of angular, but here is the function we used:

function annotatedStateObject(state, $current) {
    state = _.extend({}, state);
    var resolveData = $current.locals.resolve.$$values;
    state.params = resolveData.$stateParams;
    state.resolve = _.omit(resolveData, '$stateParams');
    state.includes = $current.includes;
    return state;
}

That will get the params, includes, and all the (resolved) resolve objects. We use that in the callback like so:

$scope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams) {
    toState = annotatedStateObject(toState, $state.$current);

    var person = toState.resolve.person;
}

I hope that helps!
