<style type="text/css">
#banner
{
padding: 5px;
position: relative;
width: 968px;
height: 293px; /*border: 1px solid #666;*/
overflow: hidden;
font-size: 16px;
}
#banner_list img

background-color: #000;
height: 30px;
filter: Alpha(Opacity=30);
opacity: 0.3;
z-index: 1000;
cursor: pointer;
width: 968px;
}
#banner_info
{
position: absolute;
bottom: 4px;

height: 22px;
color: #fff;
z-index: 1001;
cursor: pointer;
}
#banner_text
{

width: 120px;
z-index: 1002;
right: 3px;
bottom: 3px;
}
#banner ul
{

margin: 0;
padding: 0;

}
#banner ul li
{

padding: 0px;
}
#banner_list
{
margin: 0px;
padding: 0px;
width: 968px;
height: 293px;
border: #e7e7e7 1px solid;
}
</style>

代码如下:

<script type="text/javascript">
var t = n = 0, count;
$(function () {
count = $("#banner_list a").length;
$("#banner_list a:not(:first-child)").hide();
$("#banner_info").html($("#banner_list a:first-child").find("img").attr('alt'));
$("#banner_info").click(function () { window.open($("#banner_list a:first-child").attr('href'), "_blank") });
$("#banner li").click(function () {
var i = $(this).text() - 1; //获取Li元素内的值，即1，2，3，4
n = i;
if (i >= count) return;
$("#banner_info").html($("#banner_list a").eq(i).find("img").attr('alt'));
$("#banner_info").unbind().click(function () { window.open($("#banner_list a").eq(i).attr('href'), "_blank") })
$("#banner_list a").filter(":visible").fadeOut(500).parent().children().eq(i).fadeIn(1000);
$(this).css({ "background": "#be2424", 'color': '#000' }).siblings().css({ "background": "#6f4f67", 'color': '#fff' });
});
t = setInterval("showAuto()", 4000);
$("#banner").hover(function () { clearInterval(t) }, function () { t = setInterval("showAuto()", 4000); });//4秒钟切换一张图片});
function showAuto() {
n = n >= (count - 1) ? 0 : ++n;
$("#banner li").eq(n).trigger('click');
}
</script>
