I am currently using this code to add a class to every other row

  • 0

I am currently using this code to add a class to every other row in my table.

$(".stripeMe tr:even").addClass("alt");

However, on another table I’d like to add a class to rows 3,4, 7,8, 11,12 and so on…

Is this possible?

    You need to do it like this:

    $(".stripeMe tr:nth-child(4n)").add(".stripeMe tr:nth-child(4n-1)").addClass("alt");​​​​​​​​
//or...
$("tr:nth-child(4n), tr:nth-child(4n-1)", ".stripeMe").addClass("alt");​​​​​​​​​​​​​​​​​

    You can see this working here.

    Using this:

    $(".stripeMe tr:nth-child(4n), .stripeMe tr:nth-child(4n-1)").addClass("alt");​​​​​​​​

    gets different results (namely in webkit, possibly others).
