本代码高仿kendoui首页的图文切换特效，非常动感，代码部署简单。
[code]
<style type="text/css">

调用jQuery，这里使用谷歌的jquery CDN地址：
[code]
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
[/code]
JS代码：
[code]
<script type="text/javascript">
$(function() {
var len = $(".focus ul li").length;
var width = 600; //整体宽度，根据此计算偏移量
var indent = 50; //标题隐藏时往回走的一小段长度
var index = 0;
var picTimer;
var btn = "<div class='btn'>";
for(var i = 0; i < len; i++) {
btn += "<span></span>";
}
btn += "</div>";
$(".focus").append(btn);
$(".focus .btn span").mouseenter(function() {
index = $(".focus .btn span").index($(this));
play(index);
}).eq(0).trigger("mouseenter");
$(".focus").hover(function() {
clearInterval(picTimer);
},function() {
picTimer = setInterval(function() {
play(index);
index++;
if(index == len) {index = 0;}
},5000);
}).trigger("mouseleave");
function play(index) {
var $now = $(".focus ul li.on");
if($now.length > 0) {
$now.find("h5").stop(true,true).animate({left:"-" + (width - indent) + "px"},400,function() {
$(this).animate({left:"-"+ (2*width) +"px"},400);
});
$now.find("a.button").stop(true,true).fadeTo(400,0);
var hideDelay = setTimeout(function() {
$now.find("p").stop(true,true).animate({left:"-" + (width - indent) + "px"},400,function() {
$(this).animate({left:"-"+ (2*width) +"px"},400);
$now.find("div.imgBox").stop(true,true).animate({left:"-"+ (2*width) +"px"},400);
});
},200);
var showDelayA = setTimeout(function() {
show(index);
},700);
} else {
show(index);
}
}
function show(index) {
var $next = $(".focus ul li").eq(index);
$next.find("h5").css({left:"0px"});
$next.find("p").css({left:"0px"});
$next.find("a.button").css({left:"0px"});
$next.find("div.imgBox").css({left:"0px"});
$next.find("h5").stop(true,true).animate({left:"-"+ width +"px"},400);
var showDelayB = setTimeout(function() {
$next.find("div.imgBox").stop(true,true).animate({left:"-"+ width +"px"},300);
$next.find("p").stop(true,true).animate({left:"-"+ width +"px"},300,function() {
$next.find("a.button").stop(true,true).animate({left:"-"+ width +"px"},300,function() {$(this).fadeTo(400,1);});
});
},300);
$(".focus .btn span").removeClass("on").eq(index).addClass("on");
$(".focus ul li").removeClass("on").eq(index).addClass("on");
}
});
</script>
