你可以用layer分页插件实现啊
为什么不自己写一个呢。判定json数据的数据量或者id量，然后除以你每页的数据量向下取整就是你的分页数，自己用span循环插入页码用jq绑定页码不就得了~
规定用的是这个,我到分页绑定里时不会写了$("#Pagination").pagination();
原来自己也做过这样的，简单讲一下思路吧，首先不可能完全用js实现分页功能的，你需要用jsp实现数据库里相关表的数据数目查询，得到总条数，然后设置每页要显示的条数，然后利用SQL语句的limit限制条件，实现每页显示的条数，比如第一页显示的是0-4，第二页就要4-8。然后就是分页的连接，一定要设置本页面。
分页效果已有,就是不会设置jsp页面,怎么控制页面里的内容上下分页
$(document).ready(function() { $("#Pagination").pagination("${tbbwperson.totalPage}"); });分了15页,怎么让内容上下翻页?
推荐使用jqgrid，何必自己写代码呢，能用插件就用插件啊
用的就是插件,还规定要这样的样式,现在还是不能上下翻页
