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>

<meta charset="utf-8" />
<title>Page对象</title>
<style>
.pageBox,.pageBox1{ text-align:center; height:25px; padding:15px 0;}
