javascript - Angular 7 - 生产模式 : I can't navigate through page using the tab key

Question

我遇到了一个我真的无法弄清楚的问题!当我在开发模式 (ng serve) 上运行我的 Angular 7 项目时，我可以使用 Tab 键浏览我的页面(表单、链接、按钮等)。当我运行 ng serve --prod 并在本地 (localhost) 运行项目时，选项卡导航也有效。但奇怪的是，当我将生产版本放入我的服务器时，Tab 键停止工作。

我要离开我的 angular.json 文件，因为我最好的办法是这个问题与某些配置有关(只是不知道是哪个配置)

我用谷歌搜索了一遍又一遍，但没能找到任何相关的东西......

我可以看到您正在使用 fullPage.js。 该库覆盖了选项卡功能，以便在某些情况下保持正确的布局。

为了测试这是否是您的问题，您可以尝试在控制台上调用:

$.fn.fullpage.destroy();

这将破坏 fullPage.js 使用的所有 JS 处理程序，但会保留整页结构。

真正没有意义的是你只在生产中遇到问题，而不是在开发中。

无论如何，我会建议您将 fullpage.js 版本更新到最新版本。 Fullpage.js 3.X.正如您在其 changelog 中看到的那样，它摆脱了 jQuery 并解决了选项卡功能的某些问题。 .

另外，请注意您只需要包含一次 fullPage.js 并且您正在执行两次，这可能会导致问题:

          "node_modules/fullpage.js/dist/jquery.fullpage.min.js",
          "node_modules/fullpage.js/dist/jquery.fullpage.extensions.min.js"

仅使用扩展程序。
