className

[Aaron Gray]

Okay, onto className and the HTML class attribute.

When was className introduced, I believe it was introduced by Microsoft,
although I could be wrong. Now I also believe that Mozilla added support for
'className' at some point in Geko's life time, but when ?

Now the really horribly funny thing is when using getAttribute() and friends
IE only works with 'className' where as FF only works with 'class'. Funny
funny behaviour, I don't say.

Anyone educate me thurther with some details ?

Many thanks in advance,

Aaron

P.S. I could not find anything in the FAQ or any other good standard
informative source, but I maybe wrong.

Woopse its a W3C DOM construct !

Anyone educate me thurther with some details ?

Anyone know with which browsers Geko and IE introduced it ?

I am wondering if we have to use get/setAttribute() with older browsers at
all ?

Does the behaviour need lifting, or can we just use the className object
attribute for all baseline browsers ? By baseline I mean all browsers
supporting Javascript 1.5/ ECMAScript 3/ JScript 5.5 ?

IE 4 had calssName properties on its elements, Netscape 4 did not. I
have never seen and IE 3 in the flesh so I don't know anything about its
object model (and couldn't care less at this point).

Now I also believe that Mozilla added support for 'className' at some
point in Geko's life time, but when ?

Pre-release Mozzlia browsers had className properties on its elements
(including at least 0.9 to my certain knowledge), as did Netscape 6
browsers. (there were no Netscape 5 browsers)

P.S. I could not find anything in the FAQ or any other good

The HTML DOM is the only standard relevant to className properties.

Until IE8 (in Beta) IE will not handle getting/setting the class
attribute using the DOM methods getAttribute() and setAttribute().

Then again, 'class' is merely one of dozens of attributes that fail to
work properly in IE.

Check the known issues with setting (and getting) IE attributes here:
