AngularJS, the tree structure must have a root node. Usually we don't have it, because almost every view has a controller and a corresponding scope of its own.But occasionally there is some data that we want to apply globally to the entire app, when we can inject the data into $rootScope. Because other scopes inherit the root scope, the injected data is available for ng-show such as directive in the local $scope.Of course, global variables are evil a

DOM Operation Problems
Avoid using jQuery to operate the DOM, including adding element nodes, removing element nodes, obtaining element content, and hiding or displaying elements. You should use directives to implement th

This intermediary, which is the container in the dependency injection pattern, is called in the Angularjs: the injector.

From last year to this year, I participated in two projects using Angularjs as the client development framework. It mainly uses asp.net web api as the restfull service to provide the framework and angularjs combination. Angularjs, as an extension of html, is designed to build a rich set of Dynamic web applications. It

In the previous small clock example, we use AngularJS templates to rewrite the code. The exampl

Recently want to learn the use of Angularjs, online search a lap after a long day to solve the bug, the successful use of Angularjs integration Springmvc, Spring, MyBatis built a development environment. (The version used here is 4.0.6,mybatis version is 3.2.5,ANGULARJS version is 1.0.3)

In this way, we can define the prompts uniformly at the time each request is issued, and then hide the prompts after the request has ended. This code, presumably, means that when the request succeeds, it calls Deferred.resolve (data) and sets the state to success, which automatically executes the first function in then, Successcallback, and transfer the requested data into the database. When the request fails
Before writing the first Angularjs introductory article, the introduction of Ng-model said: Using the Angularjs two-way data binding mechanism, do not need us to write cumbersome code to achieve the same functionality. Now let's look at a more shocking example of how ANGULARJS reduces our tedious work in front-end development
, the instruction executes the relevant expression and updates the view using the $apply method.
When an external event (such as a user action, timer, or XHR) is triggered, the corresponding expression must be called within the $apply () method for its corresponding scope so that all listeners are correctly updated.The directives that will create scopesIn most cases, directives and scopes interact but do not produce new scope instances. However, some directives, such as ng-controller and ng
I occasionally study the front-end content, because Hbuilder was developed based on Eclipse, so it's kind of nice to use, and in the few front-end development tools I try to use, Hbuilder's performance is pretty good, and you can visit the Huilder website to download the experience.The current front-end development, the MVVM framework is very popular, more typical such as:
It is a very good idea to make DOM operation and application of logic decoupling, it can improve the regulation of code greatly.It is a very good idea to treat test and development equally, and the difficulty of testing depends to a great extent on the structure of the Code;Decoupling the client and server side is a particularly good practice, it enables both sides to develop parallel, and the two sides of the code can be reused;
