Python-Selenium: How to 'switch_to.active_element' to an input element inside a shadow dom?
问题
我正在使用Python和Selenium编写一个QA自动化脚本。
我想检查当网页渲染时输入是否已经聚焦。 我的问题是，我找不到一种方法来获取位于影子DOM内的当前聚焦输入。
HTML文档如下：
<div>
#shadow-root
#此输入元素在页面渲染时已经聚焦
<input type='text'>
</div>
我尝试过driver.switch_to.active_element，但它始终返回None，可能是因为它无法访问影子DOM。
我希望有人知道另一种获取影子DOM内当前聚焦输入元素的方法。

I am writing a QA automation script using Python and Selenium.
I want to check if the input is already focused when the webpage is rendered.
My problem is that I can't find a way to get the currently focused input that is inside the shadow dom.
HTML doc looks like this:
<div>
#shadow-root
# this input element is already focused when the page is rendered
<input type='text'>
</div>
I've tried driver.switch_to.active_element but it always returns None, probably because it can't access shadow dom.
I hope anyone knows another way to get the currently focused input element inside a shadow dom

当网页被渲染后，您会观察到<input>已经被聚焦，但Selenium的焦点在_顶层浏览上下文_。
因此，要识别<input>元素，您需要首先将Selenium的焦点置于影子根内。

英文:
When the webpage is rendered though you observe that the <input> is already focused but Selenium's focus is at the Top Level Browsing Context.
So to identify the <input> element you need to bring Selenium's focus within the shadow-root first.
