Element:prefix 属性

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

Element.prefix 只读属性返回指定元素的命名空间前缀,如果未指定前缀,则返回 null

字符串。

示例

以下代码在控制台中打印“x”。

xml
<x:div onclick="console.log(this.prefix)"/>

备注

仅当使用可感知命名空间的解析器时(即,当文档以 XML MIME 类型提供时),此属性才有效。对于 HTML 文档,此属性无效。
