Issue #94  (createComment(), JS Libs, Build Tools, Productivity)05/07/15

The Document interface allows for the creation of all sorts of stuff you might not normally think could be created. And, admittedly, many of them are probably of little use. Nonetheless, one example is the Document.createComment() method. This does exactly what the name says — it creates an HTML comment that you can then insert into the page wherever you want.

Again, I'm not entirely convinced this is of much use, but crazier things have been found to be of value. Here's an example:
var comment = document.createComment('comment text');
console.log(comment.textContent); // produces: "comment text"

(JS Bin demo)

The method itself returns the full comment object that was created, demonstrated in the line that logs it. I'm using the textContent property to display the text I inserted into the comment. I could also check the nodeType, reference its parent node (although that would be null at this point), or do all sorts of other things I could do with any HTML element.

The last line is where I actually add the comment to the page. You can inspect the live DOM in the page in the demo to see the inserted comment. You could use appendChild(), as I did, or maybe insertBefore() or something else. It's just like inserting any other node.

Support for this goes back to IE6, so it's safe to use. There's a little more info on createComment() on the Dottoro reference.
