不仅仅是当指定需要时，我也得到了这个问题时，使用最小值和最大值。

<input type="number" min="1900" max="2090" />

该字段可以根据其他无线电值隐藏和显示。因此，作为临时解决方案，我删除了验证。

确保表单中具有所需属性的所有控件也具有name属性集

这个问题发生在Chrome上，如果一个表单字段验证失败，但由于各自的无效控件无法聚焦，浏览器试图显示消息“请填写此字段”旁边也失败了。

由于多种原因，表单控件在触发验证时可能无法聚焦。下面描述的两种情况是最突出的原因:

The field is irrelevant according to the current context of the business logic. In such a scenario, the respective control should be disabled or removed from the DOM or not be marked with the required attribute at that point. Premature validation may occur due to a user pressing ENTER key on an input. Or a user clicking on a button/input control in the form which has not defined the type attribute of the control correctly. If the type attribute of a button is not set to button, Chrome (or any other browser for that matter) performs a validation each time the button is clicked because submit is the default value of a button's type attribute.

为了解决这个问题，如果你的页面上有一个按钮是做其他事情而不是提交或重置，请记住这样做:<button type="button">。

你可以禁用HTML5验证，如果你不想要它在其他回复中提到。 但如果你仍然需要HTML5验证，你可以向提交按钮添加一个“click”事件监听器来显示隐藏字段。click事件将使字段可见，验证不再抛出错误。

如果您有任何具有required属性的字段，但在表单提交期间不可见，则将抛出此错误。当您试图隐藏该字段时，只需删除所需的属性。如果您想再次显示该字段，您可以添加所需的属性。通过这种方式，您的验证将不会受到影响，同时，错误将不会抛出。

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
