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