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

This article mainly introduces how to judge the results of the validator. Here, let's look at how to implement a custom validator. Goal We want to implement a verification of the phone number of the validator, the use of the example or based on the previous article inside the example, that is, the user information entered the form page.

Why original: Hui Zhi networkAngular1.x obviously very successful, then, why do we have to turn violently to Angular2? Limitations of performanceAngularjs was originally an internal tool for designers to quickly build HTML forms. Over time, various features are added to suit the development of applications in different scenarios. However, due to the initial architectural constraints (such as bindings and templating mechanisms), performance improveme

#var-Local variablesSometimes different elements in the template may need to be called each other, and ANGULAR2 provides a simple syntax for mapping elements to local variables: Adding a property that begins with a # or var-, followed by a section representing the variable name, and an instance of the variable corresponding to the element.In the following code example, we define a local variable v_h1 for the element H1, which points to the DOM object

Reactive Extensions for Javascript was born a few years ago, and it will be recognized by more developers as the release of the official version of ANGULAR2. The core provided by RXJS is the observable object, which is a combination of asynchronous and event programming using an observable data sequence.

Preface: Recently, due to the needs of the project, the need for in-depth study of ANGULAR2, although there has been research, but because of the lack of best practices, and then real to practice when still encounter a lot of key points. Experience to: "Consider 1000 times, better to do it once." Hesitate 10,000 times, try to practice once. ”。 In the ANGULAR2 related front-end project, there will be a i18n

1. Notes The Angular2 template is used to show the appearance of the component, and as a view, the usage is basically consistent with the HTML syntax, and the simplest Angular2 template is a piece of HTML code. The angular template syntax consists mainly of the following sections: L Direct Binding L Interpolation expression L Property Bindings L Event Binding L Bidirectional Binding L Style Binding
