Question

Why is this not saving the cookie when you refresh the page?

http://jsfiddle.net/jBVBL/

Or would it be better practice to save only 1 cookie with the value of every li with “.active”

var hideshow = $(".hideShow");

hideshow.children().not(".active").each(function(index, value){
    var tis = $(this);

    if($.cookie('hideShow_id'+index) == index){
        tis.addClass(".active");
    } else {
        $(this).find("div").hide();
    }            
});

hideshow.find('h3').click(function(e){
    var tis = $(this);
    var tisindex= tis.parents("li").index;
        $.cookie('hideShow_id' + tisindex, tisindex);

        tis.next().slideToggle('2000');
        tis.parent().toggleClass('active');
    e.preventDefault();
});


<ul class="hideShow">
        <li class="active">
         <h3><a href="javascript:;">Pellentesque nec leo cursus ipsum rhoncus volutpat nec eget mi.</a></h3>

Answer 1

You are creating a different cookie for each index, and they never match the one you look for on page load. In addition, you have different cookie name strings ‘hideShow-id’ vs ‘hideShow_id’
