DOMImplementation.createHTMLDocument()
method creates a
new HTML Document

Examples
This example creates a new HTML document and inserts it into an <iframe>
in the current document.
Here's the HTML for this example:
html
<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:
js
function makeDocument() {
let frame = document.getElementById("theFrame");
let doc = document.implementation.createHTMLDocument("New Document");
let p = doc.createElement("p");
p.textContent = "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:
html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>title</title>
</head>
<body>
…
</body>
</html>
