[jQuery] Even Odd Rows

[Dave Maharaj :: WidePixels.com]

I have a li layout which have the even odd class applied to them. Each item
in the li has a delete link,click deletes the li but i am left with 
li class even
li class even
li class odd
if i delete an odd one or vice versa
 
how can i upon delete re-assign the even odd classes so they remain looking
correct?
 
thanks
 
Dave
