Description
In previous versions, calling .attr('class') on an element with no class attribute (not one with class="") returned blank. It now returns undefined.
This has the potential to break code, for example something like
$('#foo').attr('class').indexOf('bar').
Other than issue #9468, I can't find any mention of this issue. Tested only in FF4.

This is due to a fix in attr in 1.6 as that is the intended behavior. It should return the attribute value or undefined if the attribute is not present on the element.

Same results in IE8
