使用ElementInternals API的自定义元素元素不能使用delegatesFocus: true与shadowRoot，因为元素必须直接接收焦点(目前，这可能会发展)在公开的表单的DOM树(父表单可以在shadowRoot，它只是必须在同一部分的树与自定义和其他表单元素);元素必须是可见的，在我的实验中tabindex=0是必需的元素(-1似乎也工作)

一个从googlchrome扩展的带有自定义元素的演示在https://jimmont.github.io/samples/report-validity/

the error is simply reporting that an element which has attributes indicating it needs validation cannot receive focus when there's a problem with the validation, so the user can correct the error; if the error and information is coming in as expected you can ignore the error; otherwise it's likely the result of some UI features hiding elements and a mix of unexpected behavior; it's possible to use another approach in implementations to allow the user to walk back through a flow of some sort, but it appears that's beyond the scope of the question at the moment

就我而言…

Ng-show被利用了。 Ng-if被放到了它的位置，修复了我的错误。

对我来说，问题是在div中输入类型电子邮件的可见性:隐藏，类似这样的东西

<form>
  <div style="visibility: hidden;">
  <input type="email" name="email" id="email">
  ............
</form>

然后你可以改变type="email"为type="text"或删除可见性:隐藏;

在您的表单输入中。你把需要的保存在隐藏输入中，这就是为什么它抛出:

An invalid form control with name='' is not focusable

检查抛出无效的输入名称，您将其隐藏并保留为必需的。

只需从隐藏的输入名称中删除所需的。完成了。

您可以尝试. removeattribute ("required")用于那些在窗口加载时隐藏的元素。因为很有可能由于javascript(选项卡表单)，所讨论的元素被标记为隐藏

e.g.

if(document.getElementById('hidden_field_choice_selector_parent_element'.value==true){
    document.getElementById('hidden_field').removeAttribute("required");        
}

这应该可以完成任务。

这对我很管用……干杯
