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.
