没有理论介绍，只有代码，这就是今天jquery 教程的内容，呵呵。
1、html代码
复制代码 代码示例:
<div class="fleft main-con" id="focus">
<div id="banner_bg"></div>
<div id="banner_info"></div>
<ul>
<li class="on">1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
<div id="banner_list">
<a href="
javascript:void(0);"><img src="UpFile/201301/1.jpg" alt="" width="485" height="232" /></a>
<a href="javascript:void(0);"><img src="UpFile/201301/2.jpg" alt="" width="485" height="232" /></a>
<a href="javascript:void(0);"><img src="UpFile/201301/3.jpg" alt="" width="485" height="232" /></a>
<a href="javascript:void(0);"><img src="UpFile/201301/4.jpg" alt="" width="485" height="232" /></a>
<a href="javascript:void(0);"><img src="UpFile/201301/5.jpg" alt="" width="485" height="232" /></a>
<a href="javascript:void(0);"><img src="UpFile/201301/6.jpg" alt="" width="485" height="232" /></a>
</div>
</div>
2、jquery代码
复制代码 代码示例:
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")});
$("#focus li").click(function() {
var i = $(this).text() - 1;
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);
document.getElementById("focus").style.background="";
$(this).toggleClass("on");
$(this).siblings().removeAttr("class");
}); //by http://www.jb200.com
t = setInterval("showAuto()", 4000);
$("#focus").hover(function(){clearInterval(t)}, function(){t = setInterval("showAuto()", 4000);});
3、css代码
复制代码 代码示例:
#focus {position:relative; width:484px; height:232px; border:1px solid #666; overflow:hidden;}
#banner_list img {border:0px;}
#banner_bg {position:absolute; bottom:0;background-color:#000;height:30px;filter: Alpha(Opacity=30);opacity:0.3;z-index:1000;cursor:pointer; width:478px;}
#banner_info{position:absolute; bottom:0; left:5px;height:22px;color:#fff;z-index:1001;cursor:pointer;}
#banner_text {position:absolute;width:120px;z-index:1002; right:3px; bottom:3px;}
#focus ul {position:absolute;list-style-type:none;filter: Alpha(Opacity=80);opacity:0.8; border:1px solid #fff;z-index:1002; margin:0; padding:0; bottom:3px; right:5px;}
#focus ul li { padding:0px 8px;float:left;display:block;color:#FFF;border:#e5eaff 1px solid;background:#6f4f67;cursor:pointer}
#focus ul li.on { background:#900;}
#banner_list a{position:absolute;}
