Angularjs inside $emit, $broadcast, $on, $http. Jsonp,constant is the use of notes

This film mainly introduces $emit, $broadcast, $on often developed usage!

This figure is pretty much the $emit, $broadcast the mechanics and the useful in AJ!

This article describes the principles and places of attention of AJ inside using JSONP! Below is a direct display of the interface I run up! Then paste the DOM and JS code, this article does not say much, share some common things! Dom+js Code:
