Should jQuery normalize this IE6 bug involving <input/> names?

[Brian Peiris]

The alerts in following code do not show the same result in IE6 due to
a bug[1] (also discussed on stackoverflow.com[2]).

$('<input type="hidden" />').attr('name', 'foo').appendTo
(document.body);
alert(document.getElementsByName('foo').length);  // Alert shows "0"
in IE6 and "1" in other browsers


$('<input type="hidden" name="bar" />').appendTo(document.body);
alert(document.getElementsByName('bar').length);  // Alert shows "1"
in all browsers.

Working demo: http://jsbin.com/urajo

Should jQuery normalize or at least warn the user about this
discrepancy (like it does when attempting to change the 'type'
attribute on <input/> elements)?

That's a well-known bug for those of us who lived through the dark
time when IE6 was the most popular browser in the world (for some
definition of popular).

At this point it doesn't seem worth the extra convoluted code to
normalize, since the bug is already documented in a lot of places and
easy for users to work around. Is there a place that makes sense to
mention this in the jQuery docs? If the docs had mentioned it, would
you have found the mention and avoided the bug? Or would it simply
have been one of the first results for your Google of "jQuery ie6
input name bug"?  :-)

I think jQuery Docs should warn about well known bugs (that will never
be feasible to fix because of bad browsers like IE6).

There will always be newcomers and all are not equally knowledgeable
about "how to use search".

I agree that documentation of these pitfalls, specifically with
relation to jQuery, would be very useful (in addition to sites like
http://webbugtrack.blogspot.com) and I also realize that attempting to
fix this IE6 bug in jQuery would be a waste of time.

In my defence, I'm not usually the type who doesn't RTFM or try a
Google search first. This bug seems obscure to me -- obscure enough to
escape even a thorough search.
I wasn't a web-dev when IE6 was prominent and neither were many new
web-devs, I'm sure other people have and will hit their head against
this.

The good news is that a Google search for "jQuery ie6 input name
bug" (without quotes) links to this discussion on the first page :)
