AngularJS access parent scope from child controller

Question

I\'ve set up my controllers using data-ng-controller=\"xyzController as vm\"

I have a scenario with parent / child nested controllers. I have no problem

Answer 1

Perhaps this is lame but you can also just point them both at some external object:

var cities = [];

function ParentCtrl() {
    var vm = this;
    vm.cities = cities;
    vm.cities[0] = 'Oakland';
}

function ChildCtrl($scope) {
    var vm = this;
    vm.cities = cities;
}

The benefit here is that edits in ChildCtrl now propogate back to the data in the parent.
