The approach in Gump's wrapper varies as it pulls the target node from the document.

function convertNodeToString ( node ) {
   var tempNode = document.createElement( "div" );
   tempNode.appendChild( node.cloneNode( true ) );
   var stringified = tempNode.innerHTML;
   tempNode = node = null; // avoiding memory leaks in IE
   return stringified;
}

If you want to display the resulting string on the screen with escaping:

var escapedString = convertNodeToString( node ).replace( "<" , "&lt;" ).replace( ">" , "&gt;");
outputNode.innerHTML += escapedString;

Please note that properly stringifying attributes such as "class", "id", etc., may be questionable.

It has been a while since the last responses. Here is a simpler method that I have discovered:
I recently learned that .outerHTML is now supported by all major web browsers (check caniuse for more information). You can easily retrieve the HTML content of a JavaScript element using this:

// Let's create a sample HTMLDivElement
var Box = document.createElement("div");
Box.className = "box";
Box.textContent = "Lorem Ipsum";

// Output the element's HTML to the console
console.log(Box.outerHTML)

The output will be:

<div class="box">Lorem Ipsum</div>

To add text to a newly created element, you should first create a text node like so:

var newElement = document.createElement("span");
newElement.className = "highlight";
// Create text node
var textNode = document.createTextNode('Sample Text');
// Append text node to the new element
newElement.appendChild(textNode);
// Add the new element to the body
document.body.appendChild(newElement);

My component was an object containing component : HTMLDivElement, which is why this solution worked perfectly for me.

console.log(box.component.outerHTML);

If you only have the HTMLDivElement itself, you can use the following:

console.log(box.outerHTML);
