Question

given this html

    <div class="my_div">a</div>
    <div class="my_div">b</div>
    <div class="my_div">c</div> 
    <div>other</div>

I want select all .my_div element, but not last element from this class, this works not correct

            $(".my_div:not(:last-child)").css({
                color: "#090"
            });

how can select all element from some class, except last element?

Answer 1

:last-child is exactly that, the last child, not the last child of a given tag.

jQuery offers the :last selector, which does what you want, but has the cost of being something jQuery does rather than something the browser does. Thus:

$("div.my_div:not(:last)").css({
    color: "#090"
});
