The angular JS framework is briefly described in the previous section, where the angular bootstrap (bootstrap) and compiler (compilation) mechanisms will continue.
One: Initialization of Bootstrap:angular
The initial automation recommended by 1:angular is as follows:
2: Manual initialization:
If you want to have more control over the initializati

In order to allow users to adapt to the new Web site, introduced in the system "user-led" function, for most sites, this is a very common function. So before you develop this task, try to abstract it, separate it from the business logic of your existing system, and encapsulate it as a general-purpose plug-in, making it easier to extend and maintain your code.Looks like a look at the effect chart
The use of this trainning plug-in is simple, it takes the same configuration as

$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 benefits of Dependency injection (DI) are no longer mentioned, as is known with the spring Framework. Angularjs as the foreground JS framework, also provides the support for Di, this is javascript/jquery not have the characteristic. In Angularjs, Angular.module (), Angular.injector (), $injector, $provide are associated with Di. For a DI container, you must have 3 elements: the registration of the service, the Declaration of the dependency, and the acquisition of the object. For example, in
I front-end small white, but in the company to do a PC-side program, with angular write, had to self-taught a angular frame. Although in the course of work reluctantly enough, but think that since the use of a little to understand a little more comprehensive, so spent a few nights to see the angular developer guide, probably know a little bit
The previous development (web or mobile) front-end primarily uses jquery+ native JS, and if some front-end UI frameworks are used, it might itself provide some APIs to use. And now a lot of UI frameworks are based on jquery, so say that from jquery across to Angularjs span, study for a period of time Angularjs, the following from the overall feel it:About the comparison with jqueryFirst, angular is an MVC framework that differs from jquery in that it

This article describes the basic configuration of spring boot and angular the method of integrating spring boot and spring security. The current popular JWT is more suitable for integration with angular than the csrf provided by spring secuity. In addition, Springfox-swagger and Spring-boot-starter-actuator are introduced, demonstrating how to use swagger to generate JSON API documentation and how to use ac
The example in this article describes how angular ngclick prevents bubbling from using default behavior. Share to everyone for your reference, specific as follows:
This is actually a very simple question, and if you have taken a serious look at angular's official API documentation, you don't want to record it. But this question has been asked more than once, so it's recorded here today.

ObjectiveWith spring Boot2.0 officially released, Spring Webflux formally came to the spring boot big family. I am interested in this because spring Webflux can achieve higher concurrency with fewer threads and use less hardware resources to implement extensions. At the same time Angular6 also released, also want to try their own angular foundation, then based on angular and spring Webflux do a simple Gift
Angular model objects with JavaScript classesThe missing piece in AngularJS Unlike Backbone and Ember, AngularJS does not provide a standardized-to-define model objects. The model part of mvc*-Angular is the scope object, which are not, and we mean by model objects. A model object is the JavaScript version of a class instance. Developers familiar with object oriented programming would feel right at home usi
In angular, we can make Ajax requests very conveniently. We just need to inject $http, make an AJAX request – and then we can get a promise object and make it easy to call the success or the error method. For example, the following code:
$http. Get ('/foo/bar ' + itemId)
. Success (function (data) {
data;//{foo: ' Bar '}
})
. Error (Function ( Data,status,headers,config) {

Angular combination of Easyui this is not very appropriate, because: one of the characteristics of angular is two-way binding, page elements and page logic decoupling; Easyui is the encapsulation of page elements, and even some components are hidden from the original DOM elements, Creates a new element to implement functionality when initialized. In a way, angular
Vue.js is an open source JavaScript framework that helps developers to build beautiful WEB interfaces. When used in conjunction with other network Tools, Vue.js's excellent functionality will be greatly enhanced. Today, many developers have begun to use Vue.js to replace Angular and React.js.So for Angular and react.js, how do developers choose?We will introduce and contrast these two frameworks in depth.Vu
