HTML结构:
ul._rollSe{width:100px;height:300px;over-flow:hidden} ul._rollSe li._rollPar{height:100px;border:1px solid #369}
<div class="_rollParent"> <ul class="_rollPageSe"> <li class="_rollpage">1</li> <li class="_rollpage">2</li> </ul> <div> <a href="#" mce_href="#" class="_scrollPrev" data-frequency="3" data-pr="happy">上一页</a> <a href="#" mce_href="#" class="_scrollNext" data-frequency="3" data-pr="happy">下一页</a> </div> <ul class="_rollSe"> <?php for($a=1;$a++;$a<10):?> <li class="_rollPar"><?php echo $a; ?></li> <?php endfor;?> </ul> </div>
JS引入文件:
<script type="text/javascript" src="/js/jquery//scrollTo/jquery.scrollTo-min.js"></script>
author : teresa 2011-3-28
params: 以上HTML结构必填项: 有关的class
_rollParent: 触发事件的上级层)
_rollSe :滚动区域
_rollPar: 滚动元素
_scrollNext: 下一页按钮
_scrollPrev: 上一页按钮
_rollPageSe : 分页区域
_rollpage: 页码元素
data-frequency: 滚动频率 (eg:一次滚动3个元素) ->需标注在触发事件的按钮上.
data-pr: cookie的前缀.
discription: 一次性读取几条数据, 只显示几条, 滚动翻页(一次性滚3条或n条) ; 此方法只需在所需事件滚动效果的html元素标注以上规定class便可使用.
JS初始化方法:
