It is spelled _FAQ_, and the server is frequently down, unfortunately.
Also, I do not think that the FAQ covers this subject.

I value David's pointing out that the Webkit bug with dynamically created 
`button' elements can be worked around with setAttribute(), as I had 
problems with that when creating widgets (for a quick solution I had opted 
to use `input[type="button"]' elements instead of `button' elements, but the 
latter are more flexible).

Also, it is important to realize that the value of an attribute as retrieved 
with getAttribute() can be misleading.  For a practical example, there is 
(was?) a jQuery UI component which attempted to provide a fallback for 
HTML5's type="date".  But it used jQuery's attr() method for detection.  
Since the attr() method always uses the getAttribute() method in Gecko-based 
browsers, the plugin was unable to detect that Firefox did not support the 
attribute's `date' value (the attribute property yielded "text" which would 
have shown that), and that applying the fallback was indicated.  As a 
result, the corresponding `input' element stopped working in Firefox (text-
based date input impossible, as all keyboard events had been canceled by the 
plugin) until that jQuery plugin had been eliminated from the project's code 
base.
