how to check if fancybox exists on page already

Question

I am trying to check if a fancybox has been loaded already. If so then I run an ajax script to put content inside.

If not I open a fancybox iframe and it fetches content

I made it work with below code:

if(typeof $.fancybox == 'function') {
     fancy box loaded;
} else {
     fancy box not loaded;
}
