Rails spinoffs - Mar 2006 - RE: manipulate <td>''s and their contentbygrabbingtheir classNames

Ahh... Haven''t run up against that yet. Although I also completely
disregard Gecko/Safari and other totally crappy, useless, browsers :-).

You''ll probably want to make sure the tr elements are TR tags and the
same for the td''s, as empty text nodes are inserted randomly by the
gecko engine (and maybe others).

Thanks for your reponses Guys, especially Ryan & troels.

Like I mentioned earlier, what do you think about using the $$ function?

This time I''ll take an example -

$$(''table#main td.active'').each(updateClassName(elm,
newClass))

Find all <td> elements with class "active", all inside  the
<table> with id "main" and update their class to notactive.

I''ll write updateClassName myself.

Let me know what you think.

Thank you,
Mandy.

Troels'' code would be faster in any case. It also has constant speed,
whereas

grows linear with the number of td.
