[jQuery] Re: change certain elements in result set based on position

You can loop over the colors also just by using the modulo operator
instead:

$('a').each(function(i){
i = ++i % 4;
var color =
i == 1
? 'red' : //first 4
i == 2
? 'blue' : //second group of 4
i == 3
? 'yellow' : // third group
'lime'; //fourth group and so on
$(this).css('backgroundColor', color);
});
