Injection-InjectorIn the example code in the previous section, the component Ezalgo instantiates a Ezalog object directly in the constructor, which results in strong coupling between Ezapp and Ezalgo, which we can decouple using ANGULAR2 's injector/injector :Injector is like a marriage introduction , the man in the Shang registration of the female characteristics, about good meeting place , then, wait for delivery. Like what:The Ezapp component (man

Previous. NET core and ANGULAR2-1 used the dotnet template. I used it because I wanted to write a webapi, but I wrote the next one when I had some problems, so I wrote a branch test first. This time with node as the server--webpack-dev-server. Feel the demo is so easy!First, create a new project directory, here for F:\Visual Studio Code\app1Second, add the JSON configuration file under the project root: Package.json, Tsconfig.json, Typings.json{ "Nam

The usage and example of Input and Output in Angular2 are described in detail. The Input and Output in angular2 can be compared with the instructions in AngularJS. Input is equivalent to binding the command value, either one-way (@) or two-way (= ). The value of the parent scope is "input" to the sub-scope, and then the sub-scope is processed. Output is equivalent to the method binding of the instruction, a

In this section, we'll learn how to use ANGULAR2 to show the data, and how to use its built-in directives NgFor andNgIf First make sure you have a ANGULAR2 sample program that you can run, preferably the QuickStart small project that we completed in the previous chapter, or the QuickStart project that you completed on the website above, because our explanation is on that basis; Then let's start the happy j

Angular2 How to extract public components Angular2 why not need to mention public components How to communicate between parent and child components When should I use Ngmodel? Why do you use typescript? I like JavaScript. Why do I have

1. ModularComponent-based programming is a trend in web development, and ANGULAR2 provides an efficient and simple way to develop components so that program development pays more attention to the implementation of business logic, without caring about how to load components and modules, how to reference and dependency injection implementations, and so on.As shown in the following code, ANGULAR2 provides anno

JQuery makes it easier to manipulate the DOM. Due to its ease of use and scalability, Jquer also quickly swept the world, a variety of plug-ins are also dizzying.I'm sure a lot of people don't go straight from jquery to the front, because it's so easy to use, and most of what we used to do is based on jquery and its plugins. And now Angular2 's component ecology is not perfect, we may want to use jquery when writing angular. This article provides a br

I know Angular2 's idea of using jquery might see a little bit of an odd lot of you, and we all know that ANGULAR2 is responsible for managing everything related to our view components and DOM elements, which sounds like a good idea, and a working corner made with another frame can be easily done.In other words, why would anyone want jquery and ANGULAR2 integrati

Today we are going to talk about the second part of the NG2 route, including the knowledge points of routing nesting, routing life cycle, and so on.ExampleThe example is still an example of the previous lesson:Last lesson, we explained the Hero list, this lesson we explain the crisis center.Source:Https://github.com/lewis617/angular2-tutorial/tree/gh-pages/routerHow to run:Run under the root directory:Http-serverRouting NestingWe defined the routing U

A module in ANGULAR2 refers to a class that is decorated with @ngmodule. @NgModule use a metadata object to tell angular how to compile and run the code. A module can contain components, directives, pipelines, and can declare their access rights public so that the components of the external module can access and use them. module is used to organize the application, through the module mechanism external class library can be very convenient to extend t

Angular2 a modular view of Web applications, a Web application developed using ANGULAR2, is a component tree. Components are broadly divided into two categories: a generic component such as list, table, and universal, a business component designed for business development. Most of the time in actual development we need to deal with business components. For spa applications, a common problem is how to contro

Previous Article Angular2 Introductory series Tutorials-Multiple components, master-Slave relationsIn programming, we typically separate the data provided to avoid repeatedly copying the code that pastes the data request during the program's writingThe concept of dependency injection is provided in Angular2 so that we can do it gracefully. Simply described here, dependency injection allows us to write code

Due to the rise of Angular2 soon, the relevant plug-ins are still very few, so sometimes have to use some jquery plug-ins to complete the project,So how do you put the jquery plugin in the angular2? Use custom directives!To introduce jquery before the context, this no longer describesFirst, create a directive that uses the @input method to get the parameters required by the jquery plugin.In Ngonchanges, whe

The last to do the route part of the hero, there is a URL problem, this time I follow the tutorial inside the vs2015 integrated way to find styleurls: ['./app/app.component.css '] This time can not find, to replace styleurls: [' App.component.css '] ....

Maybe it's because the file location of ' My-app ' has changed.This does not matter, this time mainly writes the IFRAME question.Vs inside built such a homepageThen My-app element in the Welcome page inside, run, en, page out

And then for the ANGULAR2 project operating principles have some new experience, here and June mutual encouragement.

Shadowdom-Encapsulating private stylesANGULAR2 uses shadowdom as the rendering basis for the component, which means that the component is rendered to a separate shadow tree, which is good for good encapsulation of DOM objects and styles:The problem is that most browsers, except for Chrome, do not currently support Shadowdom, so ANGULAR2 provides three strategies for rendering templates to the DOM.Taking the following template as an example, we look at

OverviewANGULAR2 's official recommendation should be to use SYSTEMJS to load, but when I use the tree shaking, I find that if I use Systemjs+rollup, I can only package it into one file, and then lazy loading can't do it.So I used webpack2,webpack2 with the tree shaking, as long as the Tsconfig in the module set to es2015, although the effect is not rollup good, but support lazy loading.In addition, ANGULAR2 currently does not support typescript 2.1.X
