I came to this because I intergrated the jquery-fileupload plugin and noticed that there is an error when uploading a file. The reason is the the plugin fires the change event and the check fails because elem.form is null instead of undefined. This brings an error
"TypeError: elem.form is null"
for the line:
"var self = elem.form.H5Form"
not the end of the world but also not nice. There might be other ways to go around that but this is what I did and it worked.

It is a different error message but essentially the same issue, I think my check goes a bit further but I am not the javascript expert
I think my check goes a bit further ..
but here no need such precision, enough just if(!elem.form) 
also your check do not count a couple states that also equals false, like elem.form = '' elem.form = 0 elem.form = false
I can confirm that the problem is fixed with "if(!elem.form)"
