How to find first element that is hidden by JQuery

Question

I want to show first element that is hidden by jquery. my html code is:

<ol>
    <li>1</li>
    <li style="display:none">2</li>
    <li style="display:none">3</li>
    <li style="display:none">4</li>
    <li style="display:none">5</li>
    <li><a class="add">Add More ...</a></li>
</ol>

I want to show first hidden LI, each time that "a" element was clicked. My solution is below. but I think better way exists.

$("a.add").click(function(){
        var hiddens=$(":hidden",$(this).parent().parent());
        if (hiddens.length>0)
        {
            hiddens.each(function(index,el){
                if(index==0)
                {
                    $(this).slideToggle("fast");
                }
            });
        }

        if (hiddens.length==1)
        {
            $(this).parent().hide();
        }

Answer 1

Just add a :first selector after you get :hidden set so you get the first element from set found by :hidden selector

$("a.add").click(function(){
    $(":hidden:first").slideToggle("fast");
});

    $(":hidden:first").show();
