It'll be more efficient if you store the elements you're going to
manipulate into a variable. Also, since you're doing the same thing
twice, you could make it into a function.
e.g.
<script type="text/javascript">
$(document).ready(function()
{
var getTrs = $('tbody.bevker tr');
function changeTrs(){
getTrs.each(function(i){
$(this).removeClass();
(i%2)? $(this).addClass('row0
odd') : $(this).addClass('row1
even');
});
};
changeTrs();
$('th').click(function()
{
changeTrs();
return false;
}
);
}
);
</script>
