This section will explain in detail the usage process and core concepts of the Browser Action API, so that you can master the skills to create powerful extensions. By reading this section, you will understand the basic concept, role and importance of the Browser Action API, as well as how it works and its configurable items.
1. Basic introduction
Before we dive into the Browser Action API, let's go over some basic concepts. Browser Action is an extension type that allows developers to create a button in the browser toolbar that users can click to interact with the plugin. This button is pinned to the browser toolbar, providing easy access to the add-on's functionality no matter which web page the user is on. The Browser Action API provides a set of methods and events for managing and controlling the behavior and appearance of this button.
Simply put, it allows you to add an icon in the browser toolbar so that users can click a button to open the extension's UI page, perform certain actions, or view the extension's status, etc.
The Browser Action API is event-driven. When the user interacts with the plug-in buttons, the browser fires corresponding events, and the plug-in can then respond to these events by adding event listeners.
Next, let's use the Browser Action API to create our own custom button.
