The Node.prefix read-only property returns the namespace prefix of the specified node, or null if no prefix is specified. This property is read only.
Syntax
string = element.prefix
Examples
The following alerts "x".
<x:div onclick="alert(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.
Specification
- Node.prefix (introduced in DOM2)
