[jQuery] Selectors

[jQuery] Selectors

Here's what I'm trying to do. When I click on a tr i'd like it to hide
then re-style the table to alternate gray rows.
So on click I hide the tr then run this at the end of the animation/
hide
$('tr .myToggle').removeClass('gray');
$('tr .myToggle').not(':hidden').not(':even').addClass('gray');
I want to know if there is a better way of writing the second line:
$('tr .myToggle').not(':hidden').not(':even').addClass('gray');
I've tried:
$('tr .myToggle:not(':hidden'):odd').addClass('gray');//does not work
And some other variations on that. If i leave off the :not(':hidden')
i'll get all rows whether hidden or not, which means coloring odd or
even rows will not work, it won't look stripped.
Anyway does anyone know how to do this in the selector? Or could you
point me to some documentation on how to write selectors?
Thanks!
