Javascript – Append HTML to container element without innerHTML

I am surprised that none of the answers mentioned the insertAdjacentHTML() method. Check it out here. The first parameter is where you want the string appended and takes (“beforebegin”, “afterbegin”, “beforeend”, “afterend”). In the OP’s situation you would use “beforeend”. The second parameter is just the html string.

Basic usage:

var d1 = document.getElementById('one');
d1.insertAdjacentHTML('beforeend', '<div id="two">two</div>');
