這篇文章主要介紹了jquery分頁對象使用示例,需要的朋友可以參考下

使用方法和相關參數如下：
displayId//默認值顯示區域Id為pageBox，可以不填
pagesize//每頁條數，默認是15條，可以不填
totalsize//總條數
curpage//當前頁數
simple//默認是false，true沒有上一頁和下一頁，
type//0默認走http跳轉，1是jsp頁面必須有pageCallBack(pageNum)函數,從1開始
url//鏈接地址，如果type出入1此處就可以不填
例子：Page._run({totalsize:300,curpage:11,type:1,simple:true}

復制代碼代碼如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Page對象</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>
<script type="text/javascript" src="../jquery/jquery.js"></script>
