    \[code\]function create(htmlStr) { var frag = document.createDocumentFragment(), temp = document.createElement('div'); temp.innerHTML = htmlStr; while (temp.firstChild) { frag.appendChild(temp.firstChild); } return frag;}function add(identifier, html){ var frag = create(html); document.body.insertBefore(frag, document.getElementById(identifier));}\[/code\]\[code\]identifier\[/code\] is the string id of a tag that I've verified in developer tools exists, \[code\]html\[/code\] is just the fragment I want to prepend to the element denoted by said \[code\]identifier\[/code\]. \[code\]frag\[/code\] is a bonefide html fragment, and the call to \[code\]getElementById\[/code\] returns a bonefide element ie neither are strings. Why am I getting the above error on \[code\]insertBefore\[/code\]?
