[jQuery] DOM traversal -- need both parent node and siblings

[Kevin Major]

Hello everyone,

I'm currently in a bit of a bind.  I have a checkbox that's within a
table cell.  I want it so when the input is clicked, the parent table
cell AND its siblings change their classes.  I can get to the parent
element, but how would I attach this functionality to its siblings?

Right now, I have:

$(document.forms["Grid"].elements["grid[]"]).toggle(function()
{
   $(this).parent().addClass("active");
},
function()
{
   $(this).parent().addClass("inactive");
});

(I'm not using toggleClass because I have formatting within the
"inactive" class that's different than some of the other elements)

Would adding something like:

.end().siblings().addClass("active");

To the end of my statements remedy the issue?
