ANGULAR+BOOTSTRAP3 navigation MenuThe ANGULARJS experiential Programming series will show you how to build a powerful web front-end system with ANGULARJS. Angularjs is a very good web front-end framework developed by the Google team. Under so many web frameworks, Angularjs can stand out from architecture design on superior, bidirectional data binding, dependency injection, directives, MVC, templates.

The recent period has been a very exciting time for front-end engineers, as the three web frameworks are releasing new versions, giving us a glimpse of a more powerful web framework. Ember2.0 was released 2 months ago, and upgrading from 1.0 to 2.0 is very simple. A few weeks ago, react released version 0.14. There are also many popular front-end frameworks, like backbone, knockout and Aurelia. If you want to develop a web app, it is recommended to use one of the three frameworks of

PrefacePeople who have known angular know that a big feature of angular is two-way data binding. The so-called bidirectional data binding, that is, when any data in the view changes, its corresponding scope model is automatically updated, and when the scope model changes, the data in view is updated to the most recent value. So how does it work, $watch how it works, what $apply and $digest are used to do, a
$compile, in angular, the "compile" service, which involves the "compile" and "link" phases of the angular application, based on the angular root node (Ng-app) and the constructed \ $rootScope object from the DOM tree. The descendants of the root node are parsed in sequence, the instructions are searched according to a variety of conditions, and the related opera
The performance of the MVVM framework, in fact, depends on several factors:
Number of Monitors
How data changes are detected and bound
Performance of indexes
The size of the data
Structure of the data
We want to optimize the performance of the angular project, but also need to start from these aspects.1. Reduce the number of monitoring valuesHow do you reduce the number of monitoring values?Consider the extreme situation,
About angular, has always been a kind of foggy feeling, I think many developers, especially after the end of the programmer, for the scope controller service in angular has a lot of special feelings, it is a word chaosThe community has given a lot of suggestions about angular's best practices, but I personally feel that the proposals themselves point to some of the conceptual ambiguities that JavaScript its

When a user accesses our app, he should be able to switch locales immediately at runtime.In view of the fact that we are developing a ANGULARJS client application, in particular we do not want users to have to refresh the page or access an entirely different URL.

This article is primarily geared towards those who are just beginning to learn angularjs and want to understand how data binding (data-binding) works,If you are already familiar with how to use ANGULARJS, I strongly advise you not to read it.Angularjs users want to know how data-binding works, they encounter a lot of terminology.such as $wacth, $apply, $digest, dirty-checking (dirty value detection) ... Wait, what are they doing?In this article I will solve all the questions and learn by combini

$ Scope is used throughout the angular app. It is associated with the data model and is also the context of expression execution. with $ scope, a channel is established between the view and the controller. The scope-based view immediately updates $ scope when modifying data, when the same $ scope changes, the view will be re-rendered immediately.
With $ scope, the Business Code of the application can be stored in the controller, and the data is store
