jquery分页对象使用示例 - Web前端

使用方法和相关参数如下：
displayId//默认值显示区域Id为pageBox，可以不填
pagesize//每页条数，默认是15条，可以不填
totalsize//总条数
curpage//当前页数
simple//默认是false，true没有上一页和下一页，
type//0默认走http跳转，1是JSp页面必须有pagecallBack(pageNum)函数,从1开始
url//链接地址，如果type出入1此处就可以不填
例子：Page._run({totalsize:300,curpage:11,type:1,simple:true}

复制代码 代码如下:
<!DOCTYPE html>
<HTML>
<head>
<metacharset="utf-8" />
<title>Page对象</title>
<style>
.pageBox,.pageBox1{ text-align:center; height:25px; padding:15px 0;}
.pageBox .pages a.up,.pageBox .pages a.down{ color:#6eb4ea; text-decoration:none; border:1px solid #ffffff; background:none;}
.pageBox .pages a.else{ background:none; border:none;}
.pageBox .pages a{ padding:3px 7px; border:1px solid #f3f6f6; background:#fdfdfd; margin:0 5px; color:#999999;}
.pageBox .pages a:hover,.pageBox .pages a.hover{ background:#6eb4ea; border:1px solid #6eb4ea; color:#ffffff; text-decoration:none;padding:2px 7px; }
pageBox .pages span{ padding:3px 7px; color:#999999;}
.fiv_sep{ height:3px; float:left; width:100%; font-size:4px; line-height:2px;}
</style>
