DOMImplementation: createHTMLDocument() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The DOMImplementation.createHTMLDocument() method creates a new HTML Document.

Syntax

js
createHTMLDocument()
createHTMLDocument(title)

Parameters

title Optional

A string containing the title to give the new HTML document.

Return value

A new HTML Document object.

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 handles creating the new HTML document and inserting some content into it. createHTMLDocument() constructs a new HTML document whose <title> is "New Document". Then we create a new paragraph element with some simple content, and then the new paragraph gets inserted into the new document.

destDocument stores 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, destDocument.replaceChild actually replaces the contents of the frame with the new document's contents.
