    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

    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.
