隐藏'content'属性中的Microdata属性值？

您应该使用

对于schema，请参阅遗漏/隐含信息：使用 meta 标签和 content ：

这项技术应该谨慎使用。只有使用 meta 和 content 才能获得无法标记的信息。

I work on a website that recently had Schema markup added to it, but I think it is being used wrong.

Schema gives the example of

Our website implemented it in the following way

Is the second way, our way, considered cloaking? We display the data to the user but at a different point and it is not marked up with itemprop.

In HTML5, the content attribute is only allowed on the meta element. Microdata doesn’t define it as global attribute either. But RDFa extends HTML to make content a global attribute.

According to your example, you are using Microdata. So you shouldn’t use the content attribute for span.

Microdata defines a way to add name-value pairs without having to mark up visible content: Microdata extends HTML5 to allow meta and link in body (in the future, this will be defined in the HTML5 spec directly; see the "Contexts in which this element can be used" for link and meta in the HTML 5.1 Editor’s Draft).

So instead of

you should use

For schema, see Missing/implicit information: use the meta tag with content:

This technique should be used sparingly. Only use meta with content for information that cannot otherwise be marked up.
