网上找了好多相关的。但在项目中基本都不符合要求。后来找了一个。但是他不是封装的。自己修改了一下。可以重复使用了
代码如下：
$(function(){
jQuery.focus = function(bigid,smallid,boxnum) {
//@Mr.Think***变量
var $cur = 1;//初始化显示的版面
//var $i = 5;//每版显示数
var $i = boxnum;
var $len = $(smallid+">ul>li").length;//计算列表总长度(个数)
var $pages = Math.ceil($len / $i);//计算展示版面数量
var $w = $(bigid).width();//取得展示区外围宽度
var $showbox = $(smallid);
var $num = $(bigid+" span.num li")
var $pre = $(bigid+" span.pre")
var $next = $(bigid+" span.next");
//@Mr.Think***向前滚动
$pre.click(function(){
if (!$showbox.is(':animated')) { //判断展示区是否动画
if ($cur == 1) { //在第一个版面时,再向前滚动到最后一个版面
$showbox.animate({
left: '-=' + $w * ($pages - 1)
}, 500); //改变left值,切换显示版面,500(ms)为滚动时间,下同
$cur = $pages; //初始化版面为最后一个版面
}
else {
$showbox.animate({
left: '+=' + $w
}, 500); //改变left值,切换显示版面
$cur--; //版面累减
}
$num.eq($cur - 1).addClass('numcur').siblings().removeClass('numcur'); //为对应的版面数字加上高亮样式,并移除同级元素的高亮样式
}
});
//@Mr.Think***向后滚动
$next.click(function(){
if (!$showbox.is(':animated')) { //判断展示区是否动画
if ($cur == $pages) { //在最后一个版面时,再向后滚动到第一个版面
$showbox.animate({
left: 0
}, 500); //改变left值,切换显示版面,500(ms)为滚动时间,下同
$cur = 1; //初始化版面为第一个版面
}
else {
$showbox.animate({
left: '-=' + $w
}, 500);//改变left值,切换显示版面
$cur++; //版面数累加
}
$num.eq($cur - 1).addClass('numcur').siblings().removeClass('numcur'); //为对应的版面数字加上高亮样式,并移除同级元素的高亮样式
}
});
//@Mr.Think***数字点击事件
$num.click(function(){
if (!$showbox.is(':animated')) { //判断展示区是否动画
var $index = $num.index(this); //索引出当前点击在列表中的位置值
$showbox.animate({
left: '-' + ($w * $index)
}, 500); //改变left值,切换显示版面,500(ms)为滚动时间
$cur = $index + 1; //初始化版面值,这一句可避免当滚动到第三版时,点击向后按钮,出面空白版.index()取值是从0开始的,故加1
$(this).addClass('numcur').siblings().removeClass('numcur'); //为当前点击加上高亮样式,并移除同级元素的高亮样式
}
})
};
});
根据ID来加载相应的滚动区域。这里设置了。外框和内框两个部分，因为我前台页面中同样的结构。使用起来方便一点
