There was a problem hiding this comment.
This seems problematic. What if document isn't defined? Won't accessing it to make a null comparison throw an exception?
Why not do:
if (typeof document === 'undefined' || document.location == null) return '';There was a problem hiding this comment.
Thanks for catching that. I completely forgot that document is just a reference to window.document and it has to obey the same rules as every other property.
