#5655 closed bug (fixed)

Position: document check fails if the scrollTo and document plugins exist

Reported by: vjt Owned by:

Keywords: scrollTop scrollTo typo Cc: vjt@…
Blocked by: Blocking:


At line 40 there's the following conditional:

	} else if ( options.of.scrollTo && options.of.document ) {

that was causing elements to be incorrectly positioned when using options.of and the jquery.scrollTo plugin.

To me, looks like a typo, as the conditional should check for options.of.scrollTop :-)

I meant options.of.scrollTop ().

This is not a typo, we're checking if options.of has the properties scrollTo and document. This is the exact same check that jQuery core uses to determine if an element is the window. Does the scrollTo plugin also add a document property to jQuery objects?

Heh, no, it's jQuery wysiwyg that defines $.fn.document: unluckily we use it in the same page.

Thus, I think that the proper solution would be to rename plugin methods to something that doesn't clash.

Let me know if and how can I help :-).

After a quick look to the wysiwyg editor source, I saw that its $.fn.document can be rewritten as a private function, thus without polluting the namespace jQuery. I'll forward the patch to the author and keep you posted. :-)

Milestone: TBD1.9

Doesn't look there was a new release of jwysiwyg, so their $.fn.document plugin still exists.

The jQuery core code Scott was referring to seems to be this, its a private helper: {{{function getWindow( elem ) {

return ("scrollTo" in elem && elem.document) ?

elem : elem.nodeType === 9 ?

elem.parentWindow :



We could add !options.of.jquery to exclude matching jQuery instances with the right plugin methods.

Position: Handle $(document) and $(window) for the of option. Fixes #5963 - Position: option 'of' accepts jQuery object unless it wraps document. Fixes #5655 - (Possible) Typo in jquery.ui.position 1.8.1.
