全局属性itemref属性(不是具有该itemscope属性的元素的后代)可以使用一个与该项目相关联itemrefitemref提供元素标识符(不是itemid)的列表,以及文档中其他位置的其他属性。

itemref属性只能在具有指定itemscope属性的元素上指定。

注意:itemref属性不是微数据数据模型的一部分。它仅仅是一种语法结构,可以帮助作者向注释数据不遵循方便的树结构的页面添加注释。例如,它允许作者标记表中的数据,以便每个列都定义一个单独的项目,同时保留单元格中的属性。

示例

HTML

<div itemscope id="amanda" itemref="a b"></div><p id="a">Name: <span itemprop="name">Amanda</span> </p><div id="b" itemprop="band" itemscope itemref="c"></div><div id="c">    <p>Band: <span itemprop="name">Jazz Band</span> </p>    <p>Size: <span itemprop="size">12</span> players</p></div>
