一个简单的jQuery Slideshow效果 (转)

下面是一个jQuery Slideshow效果，用了一种很不错的思路。请看代码：

<div id="slideshow">
    <img src="img/img1.jpg" alt="" class="active" />
    <img src="img/img2.jpg" alt="" />
    <img src="img/img3.jpg" alt="" />
</div>

#slideshow {
    position:relative;
    height:350px;
}

#slideshow IMG {
    position:absolute;
    top:0;
    left:0;
    z-index:8;
}

#slideshow IMG.active {
    z-index:10;
}

#slideshow IMG.last-active {
    z-index:9;
}

function slideSwitch() {
    var $active = $('#slideshow IMG.active');

    if ( $active.length == 0 ) $active = $('#slideshow IMG:last');

    var $next =  $active.next().length ? $active.next()
        : $('#slideshow IMG:first');

    $active.addClass('last-active');

    $next.css({opacity: 0.0})
        .addClass('active')
        .animate({opacity: 1.0}, 1000, function() {
            $active.removeClass('active last-active');
        });
}

$(function() {
    setInterval( "slideSwitch()", 5000 );
});

大家细细品味吧。
