This is described in the aria specification. It gives the id of an element that provides some additional information about the current element that some users might need.
这在aria 规范中有描述。它给出了一个元素的 id，该元素提供了一些用户可能需要的有关当前元素的一些附加信息。

Here below is an example of how you could use the aria-describedby property. It is used when you have a text that has information about the element. Aria-describedby must be the same as the id of the text that describes it.
下面是一个示例，说明如何使用 aria-describedby 属性。当你有一个包含元素信息的文本时使用它。Aria-Describedby 必须与描述它的文本的 id 相同。
First name: <input aria-describedby="name" type="text">
<em id="name">Your first name must be correct.</em>
First name: <input aria-describedby="name" type="text">
<em id="name">Your first name must be correct.</em>
