Angularjs, as the front-desk JS framework
Angular scopes
The concept of scope (scope) runs through the Web application built with angular. Many of the instructions in the angular view are to create a scope, such as Ng-app, Ng-controller, and so on. This scope is what we injected into the write controller constructor $scope (before angular1.2), and he is a concept in the view model. Our data model is d
First, angular features:1, two-way data binding, the main selling point2. The MVVM model, separating the view and logic3. Dependency InjectionPersonal feeling, in angular, the view corresponds to the HTML template, and the view logic corresponds to the directive and controller.Second, the moduleIn Angular, a module is used to manage namespaces, and the logic of d
This section is about angular's dirty checks, features, and services.First, Dirty checkAngular internal dirty check to track data changes, which is the basis for the implementation of bidirectional data binding.The so-called dirty check, that is, angular will give each data binding a watcher, when to the "specific inspection phase", angular will be asked watcher each of its corresponding data has not change
Many Web services face not only the local users, the multi-lingual environment can not only enhance the force lattice, more important is a user experience.Angular.js as a solution to the front-end split, of course, can not be separated from the framework of the problem of internationalization, angular.js official out of a module angular-translate to solve the problem of multi-language internationalization.We use the Bower Package management tool to ma

Preface
During the holiday, the students were busy charging and learning "Full stack Development" was not a minority. I often received feedback from readers when debugging instances in the book "Full stack development path, confusions. Despite all kinds of problems, Angular debugging is a technical point in general.
It is not difficult to compile
Because the actual development need in the work, only then starts to contact the angular frame. From the original Bishi, by various problems, the concept of torture and destruction, to now have a certain understanding, feel the need to make a simple summary of their own understanding. Not in place also hope to forgive.

In this section of the tutorial, you will gradually become familiar with the most important source code files for the Angularjs phonecat app. You will also learn how to bind the development server with Angular-seed and run the app in the browser.Before you continue, make sure that you have set up your development environment and installed all the necessary dependencies, as described here.Under the angular-p

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
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

Recently, as a result of a large project revision, in order to allow users to adapt to the new revision, so in the system introduced the "User guidance" function, for the initial entry of the system users some simple use of training training. This is a very common feature for most Web sites. So before this task was developed, the blogger tried to abstract it out of the business logic of the existing system and encapsulate it as a generic plug-in, making the code easier to extend and maintain.No
