Description
Hi all, please forgive my lack of familiarity with the jQuery code, but I have found a possible bug when trying to use the NivoSlider Plugin. Although I encountered this bug when trying to use the plugin, I believe the error lies in the jQuery code.
[[BR]
When initializing NivoSlider, I received the following error:
Uncaught TypeError: Cannot read property 'defaultView' of undefined
After digging through the jQuery code, I narrowed the issue down to line 6566:
if ( !(defaultView = elem.ownerDocument.defaultView) ) {
return undefined;
}
I assumed that it was trying to obtain ''defaultView'' from elem.ownerDocument, even though "elem" or "elem.ownerDocument" may not exist. I changed the condition to the following:
if ( typeof elem === 'undefined' || typeof elem.ownerDocument === 'undefined' || !(defaultView = elem.ownerDocument.defaultView) ) {
return undefined;
}
... and everything works as expected. No errors, and the plugin works perfectly. I do not consider my code to be an elegant solution, but it may point you in the right direction if you determine this to be an error with jQuery.
Worth noting is that the error appeared in Chrome 14.0.835.186, but not in Firefox 3.6.10. I did not test in any version of IE.
Thank you for your time, and thank you for such an amazing library. P.S: the copyright on jquery.com says "2010" - may want to fix that.

This is the same as Ticket #6865 and ticket #7836, all of which have been closed. YET IT HAS JUST TRAPPED IN MY CODE, so I think all these tickets are valid, and the test should make sure elem.ownerDocument is valid before dereferencing it.

I too am getting an error on this line. I am not using any jquery plugins.

jQuery 1.6.4
Browsers:
Firefox 6.0.2 & 7.0.1

Chrome 14.0.835
Error message:

This can be reproduced at the following URL
http://jsfiddle.net/dwat001/SYQJA/19/show/

Follow up, I have just tried on jQuery version Edge and got a different error, I'm not sure this is before or after the above line of code is executed
The error I got was on line 1821
invalid 'in' operand thisCache
} else if ( name in thisCache ) {
Surrounding code:
Support space separated names
if ( jQuery.isArray( name ) ) {
name = name;
} else if ( name in thisCache ) {
name = [ name ];
} else {
split the camel cased version by spaces
the variable thisCache === true
This is occurring IE,Chrome and Firefox

What a bullshit: some user took the effort to log this bug, with a patch included and then the issue just gets auto-snubbed like that. Shame on you guys! I guess I will have to apply the patch myself to a local copy of the library. Thanks to the original poster for the detailed defect description.

Honestly, guys. This is a bug tracker. Don't send us your broken code and then ask us to debug it, blaming jQuery for whatever programming mistake you have made. The test case above has this code:
$("#floating-image").mouseleave( function(image){
$(image)
.stop()
An event handler is passed an event object as its first argument. Using the name image ***does not magically turn it into an image***.
Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.
Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: http://jsfiddle.net/FrKyN/ Open the link and click to "Fork" (in the top menu) to get started.
