The DOMImplementation.createHTMLDocument()
method creates a new HTML Document
.
Syntax
const newDoc = document.implementation.createHTMLDocument(title)
Parameters
title
Optional (except in IE)- A
DOMString
containing the title to give the new HTML document.
Example
This example creates a new HTML document and inserts it into an <iframe>
in the current document.
Here's the HTML for this example:
<body> <p>Click <a href="javascript:makeDocument()">here</a> to create a new document and insert it below.</p> <iframe id="theFrame" src="about:blank" /> </body>
The JavaScript implementation of makeDocument()
follows:
function makeDocument() { let frame = document.getElementById("theFrame"); let doc = document.implementation.createHTMLDocument("New Document"); let p = doc.createElement("p"); p.innerHTML = "This is a new paragraph."; try { doc.body.appendChild(p); } catch(e) { console.log(e); } // Copy the new HTML document into the frame let destDocument = frame.contentDocument; let srcNode = doc.documentElement; let newNode = destDocument.importNode(srcNode, true); destDocument.replaceChild(newNode, destDocument.documentElement); }
The code in lines 4–12 handle creating the new HTML document and inserting some content into it. Line 4 uses createHTMLDocument()
to construct a new HTML document whose <title>
is "New Document"
. Lines 5 and 6 create a new paragraph element with some simple content, and then lines 8–12 handle inserting the new paragraph into the new document.
Line 16 pulls the contentDocument
of the frame; this is the document into which we'll be injecting the new content. The next two lines handle importing the contents of our new document into the new document's context. Finally, line 20 actually replaces the contents of the frame with the new document's contents.
The returned document is pre-constructed with the following HTML:
<!doctype html> <html> <head> <title>title</title> </head> <body> </body> </html>
