图片切换特效实现很简单,而且兼容性很好。html页面如下
复制代码 代码如下:
<div class="wrapper">
<div id="focus">
<ul>
<li><a href="http://www.lanrentuku.com/" target="_blank"><img src="img/01.jpg" alt="QQ商城焦点图效果下载" /></a></li>
<li><a href="http://www.lanrentuku.com/" target="_blank"><img src="img/02.jpg" alt="QQ商城焦点图效果教程" /></a></li>

</ul>
</div>
</div><!-- wrapper end -->
</body>
css样式
复制代码 代码如下:
<style type="text/css">

#focus .pre {left:0}
#focus .next {right:0background-position:right top}
</style>
js脚本
复制代码 代码如下:
$(function() {
var sWidth = $("#focus").width()//获取焦点图的宽度(显示面积)
var len = $("#focus ul li").length//获取焦点图个数
var index = 0
var picTimer
//以下代码添加数字按钮和按钮后的半透明条,还有上一页、下一页两个按钮
var btn = "<div class='btnBg'></div><div class='btn'>"
for(var i=0i <leni++) {
btn += "<span></span>"
}
btn += "</div><div class='preNext pre'></div><div class='preNext next'></div>"
$("#focus").append(btn)
$("#focus .btnBg").css("opacity",0.5)
//为小按钮添加鼠标滑入事件,以显示相应的内容
$("#focus .btn span").css("opacity",0.4).mouseenter(function() {
index = $("#focus .btn span").index(this)
showPics(index)
}).eq(0).trigger("mouseenter")
//上一页、下一页按钮透明度处理
$("#focus .preNext").css("opacity",0.2).hover(function() {
$(this).stop(true,false).animate({"opacity":"0.5"},300)
},function() {
$(this).stop(true,false).animate({"opacity":"0.2"},300)
})
//上一页按钮
$("#focus .pre").click(function() {
index -= 1
if(index == -1) {index = len - 1}
showPics(index)
})
//下一页按钮
$("#focus .next").click(function() {
index += 1
if(index == len) {index = 0}
showPics(index)
})
//本例为左右滚动,即所有li元素都是在同一排向左浮动,所以这里需要计算出外围ul元素的宽度
$("#focus ul").css("width",sWidth * (len))
//鼠标滑上焦点图时停止自动播放,滑出时开始自动播放
$("#focus").hover(function() {
clearInterval(picTimer)
},function() {
picTimer = setInterval(function() {
showPics(index)
index++
if(index == len) {index = 0}
},4000)//此4000代表自动播放的间隔,单位:毫秒
}).trigger("mouseleave")
//显示图片函数,根据接收的index值显示相应的内容
function showPics(index) { //普通切换
var nowLeft = -index*sWidth//根据index值计算ul元素的left值
$("#focus ul").stop(true,false).animate({"left":nowLeft},300)//通过animate()调整ul元素滚动到计算出的position
//$("#focus .btn span").removeClass("on").eq(index).addClass("on")//为当前的按钮切换到选中的效果
$("#focus .btn span").stop(true,false).animate({"opacity":"0.4"},300).eq(index).stop(true,false).animate({"opacity":"1"},300)//为当前的按钮切换到选中的效果
}
})
