Simulated click

Timer clicks every 100 ms

Logic: after a certain time point, trigger the simulated click.

3. JavaScript Components

1. Core – based on the ECMAScript specification.

2. Document Object Model (DOM).

3. Browser Object Model (BOM).

The window object is the top‑level BOM object; all other objects are its descendants. Because window is the global object, its properties can be accessed without explicitly referencing window.

Through this tree structure, you can quickly locate the node you want to operate on and manipulate its attributes, methods, or events. Remember the distinction between elements, attributes, and content: visible content is wrapped by opening and closing tags, while attributes describe element characteristics.

4. Chrome Extension Packaging

Why package as an extension? Scripts run in the console are cleared after a reload, but an extension persists.

Package the script into an extension, then load the unpacked folder.

Load the folder in Chrome’s extensions page.

Open Baidu and click the extension button.
