Example of how AngularJS implements Data Interaction Between Custom commands and controllers
This article describes how AngularJS interacts with the Controller data by using custom commands. We will share this with you for your reference. The details are as follows:
One day the monitor said, the students want me to develop a can share the address book, so I simply designed the next function. Including user roles, publishing microblogging, sharing location, and so on. This is also a bit selfish, in order to exercise the recently seen Angularjs, so decisively choose Node.js + MongoDB + angular.js scheme.

. More accurately, $ rootScope is created by the core module ng of angularJS.
Example 1:
// Create a module var module = angular. module ("app", []); // true indicates that $ rootScope is indeed included in the module's injector as a service. var hasNgInjector = angular. injector (['app', 'ng ']); console. log ("has $ rootScope =" + hasNgInjector. has ("$ rootScope"); // true // gets the injector object o
An example of AngularJS's internal language environment

$injector, $rootScope, and $scope are important things in the AngularJS framework, and it is useful for us to follow up on the AngularJS framework of learning and understanding.1.$injector is actually an IOC container that contains a lot of services (similar to beans in the spring framework), and other code can pass $injector. Get ("ServiceName") way, Get the ser
