我遇到了一个我真的无法解决的问题！当我在开发模式(ng-server(下运行我的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，选项卡导航也可以工作。但奇怪的是，当我将生产构建放入服务器时，tab键停止工作。
我在这里留下我的angular.json文件，因为我最好的办法是这个问题与一些配置有关(只是不知道是哪一个(
我在谷歌上搜索了又一次，但找不到任何相关的东西。。。

谢谢！
我可以看到你正在使用fullPage.js。库会覆盖选项卡功能，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();
这将销毁fullPage.JS使用的所有JS处理程序，但将保留fullPage结构。
真正没有意义的是，你只有在生产中才有问题，而不是在开发中。
无论如何，我建议您将fullpage.js版本更新为最新版本。Fullpage.js3.X。它摆脱了jQuery，并通过选项卡功能解决了某些问题，正如您在其更改日志中看到的那样。
另外，请注意，您只需要包含fullPage.js一次，而且您要包含两次，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"
只使用扩展名一个。
这很奇怪。我们有以现代angular构建的应用程序，但我们从未在任何可访问性审计中遇到过这个问题。你看过标签索引了吗？如果使用自定义组件，则可能需要将tabindex="0"分配给那些应该以键盘为焦点的元素。
