AngularJS Scope Notes

Helpful links for Angular element.$on, and $scope.$watch, $digest, and $apply:

• http://docs.angularjs.org/api/angular.element
• http://docs.angularjs.org/api/ng.$rootScope.Scope
• http://www.benlesh.com/2013/08/angularjs-watch-digest-and-apply-oh-my.html

Note: Ben Lesh doesn't recommend using $apply in a controller, but in a directive or service instead.

Also helpful:

When the browser calls into JavaScript the code executes outside the Angular execution context, which means that Angular is unaware of model modifications. To properly process model modifications the execution has to enter the Angular execution context using the $apply method. Only model modifications which execute inside the $apply method will be properly accounted for by Angular.
