Question

我正在开发一个chrome插件。它会检查按钮是否连续启用。如果已启用，则会单击它。我使用无限循环，但浏览器冻结。我怀疑这可能不是一个好主意。这是 runscript.js 文件

for (;;) {
  if ($('[class="abcd"]').disabled == false) {
      $('[class="abcd"]').click();
      break;
  } else {
       console.log('button disabled');
  }
}

这里是 manifest.json 文件

{
  "name": "First extension",
  "version": "1.0",
  "manifest_version": 2,
  "description": "My extension",
  "browser_action": {
    "default_icon": "icon.png",
    "default_menu": "Menu",
    "default_popup": "popup.html"
  },
  "icons": {
    "128": "icon.png"
  },
  "permissions": [
    "tabs",
    "http://*/*",
    "activeTab"
  ],
  "content_scripts": [
    {
      "matches": [
        "https://*/*"
      ],
      "js": [
        "jquery-3.3.1.min.js",
        "runscript.js"
      ]
    }
  ]
}

有关如何正确使用它的任何建议吗？
