The Element.prefix
read-only property returns the namespace prefix of the specified element, or null
if no prefix is specified.
Element.prefix
Value
A string.
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.
