面板和内容脚本之间的沟通如何发生? 我们如何能从内容脚本动态地更新面板内容? 内容脚本可以进入已装入页面的 DOM 。 每当在面板上显示的网页上出现 DOM 更改时, 都会出现此变化 。 我们如何做到这一点? 任何人都可以举例解释吗?

请通过这个代码, 我没有得到输出
您的问题涉及两个内容脚本之间的沟通――一个内容脚本已装入网页,另一个内容脚本已装入面板。这些内容脚本无法直接沟通,他们必须通过扩展名(main.js 或任何创建它们的模块)进行沟通。换句话说:如果网页发生变更,内容脚本就承认该变更,并向扩展名发送消息。扩展名接收该消息,并将其发送到面板的内容脚本。这些面板的内容脚本随后根据需要更新面板内容。
