This article introduces the knowledge of "how to achieve two-way data binding in angular". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Angular is a MVC framework that is most suitable for developing client-side single-page applications. It is not a function library, but a framework for developing dynamic web pages. It focuses on extending the capabilities of HTML, providing dynamic data binding, and it works well with other frameworks such as jQuery.

If you are developing a single-page application, angular is your best choice. Applications such as Gmail, Google Docs, Twitter and Facebook give full play to the strengths of angular. But applications that do a lot of manipulation of DOM, such as game development, or simply require extremely high speeds, are not opportunities for angular to show its talents.

The so-called angular is not omnipotent, when it is needed, we should use it reasonably and let it play an important role.

Let me give you a small example to show you its magic!

Feature 1: bidirectional data binding

Data binding is the coolest and most practical feature of angular. It can help you avoid writing a lot of initial code and save development time. A typical web application may contain 80% of the code used to process, query, and listen to DOM. Data binding can lead to less code, and you can focus on your application.

Let's imagine that Model is a simple fact in your application. Your Model is the part you use to read or update. Data binding instructions provide a way for your Model to be projected to view. These projections can be seamlessly applied to web applications.

Traditionally, when model changes. Developers need to manually process the DOM element and reflect the attributes in these changes. This is a two-way process. On the one hand, model changes drive changes in elements in DOM, on the other hand, changes in DOM elements also affect Model. This is more complex in user interaction because developers need to deal with and parse

These interactions are then merged into a model and the View is updated. This is a manual and complex process, and when an application is very large, it will be a very laborious task.

There must be a better solution! That is the bidirectional data binding of angular, which can synchronize DOM and Model, and so on.
