I just opened the console by hitting F12 (or right-clicking and selecting Inspect element , then typed in angular . If you get the message Object {version: Object, callbacks: Object} , angular is loaded. If you get the message Uncaught ReferenceError: angular is not defined , angular is not loaded.
In AngularJS, $apply() function is used to evaluate expressions outside of the AngularJS context (browser DOM Events, XHR). Moreover, $apply has $digest under its hood, which is ultimately called whenever $apply() is called to update the data bindings. We will take an example to give a better understanding.
Definition and Usage. The ng-repeat directive repeats a set of HTML, a given number of times. The set of HTML will be repeated once per item in a collection. The collection must be an array or an object.
Digest cycle is what Angular JS triggers when a value in the model or view is changed. The cycle sets off the watchers which then match the value of model and view to the newest value. Digest cycle automatically runs when the code encounters a directive.
The solution was to call...
$scope.$apply();
...in my jQuery event callback.
$apply should be called?TL;DR:
$apply should be called whenever you want to apply changes made outside of Angular world.
Just to update @Dustin's answer, here is an explanation of what $apply exactly does and why it works.
$apply()is used to execute an expression in AngularJS from outside of the AngularJS framework. (For example from browser DOM events, setTimeout, XHR or third party libraries). Because we are calling into the AngularJS framework we need to perform proper scope life cycle of exception handling, executing watches.
Angular allows any value to be used as a binding target. Then at the end of any JavaScript code turn, it checks to see if the value has changed.
That step that checks to see if any binding values have changed actually has a method, $scope.$digest()1. We almost never call it directly, as we use $scope.$apply() instead (which will call $scope.$digest).
Angular only monitors variables used in expressions and anything inside of a $watch living inside the scope. So if you are changing the model outside of the Angular context, you will need to call $scope.$apply() for those changes to be propagated, otherwise Angular will not know that they have been changed thus the binding will not be updated2.
Use
$route.reload();
remember to inject $route to your controller.
