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。
在DOM4之前,该API是在 Node
interface 中定义的。
Syntax
string = element.prefix
Examples
The following logs "x" to the console.
<x:div onclick="console.log(this.prefix)"/>
Notes
This will only work when a namespace-aware parser is used, i.e. when a document is served with an XML MIME type. This will not work for HTML documents.
