Question

I’m working on a project with a navigation that is animated.
(Joomla working in the background)

How can i retrieve the class="item-##" only, while having multiple classes (shown below).

My jQuery

$(document).ready(function(){
    var timer;
    var hover;

    $('#nav li').hover(
        function() {
/*Here!>>*/ var id = $(this).attr('class').split('-')[1];
            $('.moduletable-subNav ul').slideUp();
            $('#submenu-'+id).slideDown();
        },
        function(){
            var id = $(this).attr('id').split('-')[1];
            timer = setTimeout(function() { $('#submenu-'+id).slideUp(); },1000);
        }
    );

    $('.moduletable-subNav ul').hover(
        function(){
            clearTimeout(timer);
        },
        function(){
            var id = $(this).attr('id');
            timer = setTimeout(function() { $('#'+id).slideUp(); },1000);
        }
    );
});

My HTML:

    <div class="moduletable">
    <ul class="menu" id="nav">
            <li class="item-109 current active parent"><a href="/tenc2012/burgerlijkrecht" >Burgerlijkrecht</a></li>
            <li class="item-110 parent"><a href="/tenc2012/strafrecht" >Strafrecht</a></li>
            <li class="item-108"><a href="/tenc2012/bestuursrecht" >Bestuursrecht</a></li>
    </ul>
    </div>
    <div class="moduletable-subNav">
            <ul class="menu" id="submenu-109">
                    <li class="item-114"><a href="/tenc2012/burgerlijkrecht/burgelijk-recht-deel-1" >Burgelijk recht deel 1</a></li>
            </ul>
            <ul class="menu" id="submenu-110">
                    <li class="item-117"><a href="/tenc2012/strafrecht/strafvordering" >Strafvordering</a></li>
            </ul>
    </div>

Answer 1

One technique that I sometimes use for this is cheating a little and using “rel” or other unused attributes to pass things like this around. Try setting:

<li ... rel="109">

and then getting:

$(this).attr('rel')

A bit of a hack, but fairly simple to do.

EDIT

Examples using karim79’s “data-number” suggestion:

<li ... data-number="109">

And jQuery:

$(this).attr('data-number')
