Next, let's step through the official API and combine the practice process to learn about this powerful framework.Note: The key level of the function is indicated by the ★ after each function description title (the "star").2, function (ON)Angular encapsulates a series of public methods that help
---restore content starts---When angular first entered the front-end developer Vision, one of the indelible impressions was its implementation of two-way data binding. This chapter first describes how to use this feature, and then explains in depth how its two-way binding mechanism is implemented.Data-binding in angular refers to the automatic synchronization between the model models and view views.
Angular JS is very good very powerful, but note that angular JS is not suitable for the operation of the DOM, although after a version of the update, angular built-in jqlite to facilitate the operation of the DOM, the intention to replace the location of jquery, it is very ulterior motives.In fact, angular the best pla

[Special statement] This article is purely my personal behavior. It is totally out of my preferences and has nothing to do with Turing.
However, it should be noted that writing this book review is entirely from the whim. Although I want to maintain neutral, I am a publisher, and the service provider can be said to be a competitor of the publishing house. Therefore, it is not a suitable reviewer, please pay special attention to this when reading the f
When there are many fields in the validation form, you may want to put the HTML generation and validation logic in the controller, on the page, perhaps:Then, define the individual fields in the controller and verify.

To work, it is critical that programmers choose the right framework and library to build applications, which is why there is too much controversy between angular and react. The advent of node. JS makes this war even more complicated, and although it's often a great thing to have a choice, in this case there is no consensus among programmers about which framework to choose, and everyone has different ideas and sounds quite reasonable.In order to make e
Angular is a well-known front-end Framework. Many of its features are cool, such as bidirectional data binding, dependency injection, commands, MVC (or MVVM), template (a bit like handlebar ). However, two-way data binding is the most discussed. The core idea of this article is the observer mode (or publish and subscribe mode). The focus of this article is to discuss how to implement the observer mode, then we will discuss how to implement simple two-
