Returns the Document Type Declaration (DTD) associated with current document. The returned object implements the DocumentType
interface. Use DOMImplementation.createDocumentType()
to create a DocumentType
.
Syntax
doctype = document.doctype;
doctype
is a read-only property.
Example
var doctypeObj = document.doctype; console.log( "doctypeObj.name: " + doctypeObj.name + "\n" + "doctypeObj.internalSubset: " + doctypeObj.internalSubset + "\n" + "doctypeObj.publicId: " + doctypeObj.publicId + "\n" + "doctypeObj.systemId: " + doctypeObj.systemId );
Notes
The property returns null
if there is no DTD associated with the current document.
DOM level 2 doesn't support editing the document type declaration.
