Question

I’ve have a page with several (about 30) same-sized divs. But the class is different for them such as:

.mosaic-block, .events, .exhibitions, .gallery, .sponsors, .hospitality, .workshops, .lectures {
    background:rgba(0, 0, 0, .30);
    float:left;
    position:relative;
    overflow:hidden;
    width:6.36896%;
    height:22.2287%;
    margin:2px;
} 

Next, I’ve a navi class such as:

<div id="navi">
    <a href="#"><div id="t0" class="n0 lfloat"><img src="images/home.png"><span>Home</span></div></a>
    <a href="#"><div id="t1" class="n1 lfloat"><img src="images/events.png"><span>Events</span></div></a>
    <a href="#"><div id="t2" class="n2 lfloat"><img src="images/workshops.png"><span>Workshops</span></div></a>
    <a href="#"><div id="t3" class="n3 lfloat"><img src="images/lectures.png"><span>Lectures</span></div></a>
    <a href="#"><div id="t4" class="n4 lfloat"><img src="images/exhibitions.png"><span>Exhibitions</span></div></a>
    <a href="#"><div id="t5" class="n5 lfloat"><img src="images/hospitality.png"><span>Hospitality</span></div></a>
    <a href="#"><div id="t6" class="n6 lfloat"><img src="images/gallery.png"><span>Gallery</span></div></a>
    <a href="#"><div id="t7" class="n7 lfloat"><img src="images/sponsors.png"><span>Sponsors</span></div></a>
</div>

My aim is that if a user clicks on Events[ie, div #t1], all boxes will fade out except those having the class .events. Similarily, for the other options as well. I’m using Jquery for this. But my code is too long.Is there any way of shortening it?

    <script type="text/javascript">
    $(function () {
    $('a #t0').click(function() {
        $("*").animate({ 
            opacity: 1.0
            }, 500 );

        });

    $('a #t1').click(function() {
        $("#t1").toggleClass("active");
        $(".exhibitions, .workshops, .sponsors, .hospitality, .lectures, .gallery").animate({ 
            opacity: 0.0
            }, 500 );
        $(".events").animate({ 
            opacity: 1.0
            }, 500 );

        });
</script>

Similarily, for #t2, #t3, #t4, etc.
Is there any way of shortening the code?

EDIT#1

I mean do I have to write .click(function() 7 times for each #t individually and exclude that class when writing $(".exhibitions, .workshops, .sponsors, .hospitality, .lectures, .gallery").animate()??

Also, how to remove .active class when the user clicks on some other option?

Give this a try: Live Demo

You have to specify a common class for all the boxes, I have used boxes.

It also handles “Home”, which will show all the divs. Sets the clicked div class to active.

<script type="text/javascript">
    $(function () {
        $('a #t0').click(function() {
            $(".boxes").animate({ 
                opacity: 1.0
                }, 500 );

        });


        $("#navi a").click(function() {
            c = $(this).text().toLowerCase();

            if(c != "home") {
                $('.' + c).animate({ 
                   opacity: 1.0
                 }, 500 );
                $('.boxes').not('.' + c).animate({ 
                   opacity: 0.0
                 }, 500 );

                $(".active").removeClass('active');
                d = $(this).find('div')[0];
                $(d).addClass('active');
            }
        });
    });
</script>
