The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. It can be set to replace the element with nodes parsed from the given string.


var content = element.outerHTML;

On return, content contains the serialized HTML fragment describing the element and its descendants.

element.outerHTML = content;

Replaces the element with the nodes generated by parsing the string content with the parent of element as the context node for the fragment parsing algorithm.


Getting the value of an element's outerHTML property:

// HTML:
// <div id="d"><p>Content</p><p>Further Elaborated</p></div>

d = document.getElementById("d");

// the string '<div id="d"><p>Content</p><p>Further Elaborated</p></div>'
// is dumped to the console window

Replacing a node by setting the outerHTML property:

// HTML:
// <div id="container"><div id="d">This is a div.</div></div>

container = document.getElementById("container");
d = document.getElementById("d");
console.log(container.firstChild.nodeName); // logs "DIV"

d.outerHTML = "<p>This paragraph replaced the original div.</p>";
console.log(container.firstChild.nodeName); // logs "P"

// The #d div is no longer part of the document tree,
// the new paragraph replaced it.


If the element has no parent node, that is if it is the root node of the document, setting its outerHTML property will throw a DOMException with the error code NO_MODIFICATION_ALLOWED_ERR. For example:

document.documentElement.outerHTML = "test";  // throws a DOMException

Also, while the element will be replaced in the document, the variable whose outerHTML property was set will still hold a reference to the original element:

var p = document.getElementsByTagName("p")[0];
console.log(p.nodeName); // shows: "P"
p.outerHTML = "<div>This div replaced a paragraph.</div>";
console.log(p.nodeName); // still "P";
