you can nest any elements inside an <a>except the following:

<a>
<a>
audio>(if the controls attribute is present)

<keygen>

<label>

<menu>(if the type attribute is in the toolbar state)

So you need to use some css to design an Button (or there is many Methods) instead of adding Buttoninside aelement.
所以你需要使用一些css来设计一个按钮（或者有很多方法）而不是添加Button内部a元素。

The usual error from the W3C validator is:
W3C 验证器的常见错误是：
The element button must not appear as a descendant of the a element
元素按钮不得作为 a 元素的后代出现
This makes more sense for your question, as you have a button that is a descendant of an anchor.
这对您的问题更有意义，因为您有一个按钮是锚的后代。
Normally, you could solve the issue by simply styling your anchor tag, or by placing the button within a form element:
通常，您可以通过简单地设置锚标记样式或将按钮放置在表单元素中来解决问题：
<form style="display: inline" action="http://www.example.com/" method="get">
<button>Some Call to Action</button>
</form>
But in your case, I don't think you even need the anchors as you aren't linking anywhere using HTML (and if you are attaching events using JavaScript, you could simply attach those events to the button rather than the anchor.
但在您的情况下，我认为您甚至不需要锚点，因为您没有使用 HTML 链接任何地方（如果您使用 JavaScript 附加事件，您可以简单地将这些事件附加到按钮而不是锚点。
