The livequery plugin (http://brandonaaron.net/docs/livequery/) might
help you. You only bind the hover function once for a selector, and
all TR's subsequently added to the tables will have the event covered
with no need to bind it again.
And just so you know, this
tbody.hover(function () {
// over
// wish rows will be exposed on 'out' (it won't)
var rows = $(this).children('tr');
tr.addClass('hovered');
}, function () {
// out
rows.removeClass('hovered'); // this doesn't work
});
doesn't work because the 'rows' var is only known inside the first
function. You have to either declare it again on the other one or use
the jquery object directly.
