jquery分頁對(duì)象使用示例

 更新時(shí)間:2014年04月01日 14:31:14   作者:  
這篇文章主要介紹了jquery分頁對(duì)象使用示例,需要的朋友可以參考下

使用方法和相關(guān)參數(shù)如下:
displayId//默認(rèn)值顯示區(qū)域Id為pageBox,可以不填
pagesize//每頁條數(shù),默認(rèn)是15條,可以不填
totalsize//總條數(shù)
curpage//當(dāng)前頁數(shù)
simple//默認(rèn)是false,true沒有上一頁和下一頁,
type//0默認(rèn)走h(yuǎn)ttp跳轉(zhuǎn),1是jsp頁面必須有pageCallBack(pageNum)函數(shù),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(fù)制代碼 代碼如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Page對(duì)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><!--jquery支持1.4以上版本-->

<body>
