?样式:
?? 主要控制 li 的宽与高。

js在html里的调用:
?
$(".carousel").jCarouselLite({ btnNext: ".next", btnPrev: ".prev"});?js地址:
??? http://www.estorm.cn/blog/demo/09/1109/jcarousellite_1.0.1.js
?
参数说明:
?? btnPrev : 上一张按钮
btnNext : 下一张按钮
btnGo : 标签控制,也就是用’1,2,3,4…’来控制
mouseWheel : 是否支持鼠标滑轮滚动,属性值:false / true;默认为false 打开此项需要jQuery UI插件支持
auto : 设置自动播放的速度,默认自动播放是关闭的,格式 auto: 800 (为播放速度)
speed : 动画效果速度
easing : 动画效果优化,姑且这么里面 需要外部插件支持
vertical : 动画方向,如果设置为true,则表示垂直滚动,默认为false
circular : 是否重复播放,如果设置为false,则到最后一个下一张按钮就点不动了,到第一张上一张按钮就点不动
visible : 设置默认显示几个li,默认是3个
start : 效果从第几个开始,默认为0
scroll : 一次滑动几个li,默认是2
beforeStart : 这个是接口,每次滑动效果执行之前执行的自定义函数
afterEnd : 这个是接口,每次滑动效果执行之后执行的自定义函数
?
主要强调的是我改一部分:
