Element.prefix
The Element.prefix read-only property returns the namespace prefix of the specified element, or null if no prefix is specified.
Before DOM4 this API was defined within the Node interface.
Syntax
JavaScript
Copy Code
<var>string</var> = <var>element</var>.prefix
Examples
The following logs "x" to the console.
XML
Copy Code
<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.
