Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The Node.prefix read-only property returns the namespace prefix of the specified node, or null if no prefix is specified.

In DOM4 this API was moved from Node to the Element and Attr interfaces.

Syntax

string = node.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.
