如何使内容脚本自动单击任何框"Hello“。

Answer 1

你不能在后台脚本中这样做。它必须在一个内容脚本中完成。

script.js

setInterval(() => {
  document.querySelectorAll('div').forEach(div => {
    div.getElementsByTagName('span')[0].innerHTML.includes('Hello') && div.click();
  });
}, 1000);

manifest.json

{
  "manifest_version": 2,
  "name": "Hello Box Clicker",
  "permissions": [
  "activeTab"
  ],
  "version": "0.0.0.1",
  "content_scripts": [
    {
      "matches": [
        "<all_urls>"
      ],
      "js": [
        "script.js"
      ]
    }
  ]
}
