以下是v1.1的版本，v1.3的请点击下载：http://pan.baidu.com/s/1pKPbPs3 密码：31bo

Documentvar pageIndex = 0; //页面索引初始值
var pageSize = 15; //每页显示数据条数
$(function () { //$(document).ready(function(){}) 的简写，文档加载完自动执行
InitTable(0); //Load事件，初始化首页数据，页面索引为0(第一页)
var pageCount = 1000;
//分页，PageCount是总记录数，这是必选参数，其它参数都是可选,
//可以在php中计算出总记录数，发到模板页，就可以根据该总数来控制显示123的数目，
//比如总共就5条数据，一页就可以，分页中的23就不必显示，因为显示的话点击也是空值。
$("#Pagination").pagination(pageCount, {
callback: PageCallback, //PageCallback() 翻页调用此函数。
prev_text: "←上一页",
next_text: "下一页→",
items_per_page:pageSize,//每页显示数据条目数
num_edge_entries: 3, //当分页非常多时，两侧首尾分页条目数为3条，不显示的部分用省略号代替
num_display_entries: 9, //当分页非常多时，连续分页最多显示9条，不显示的部分用省略号代替
current_page: pageIndex, //当前页索引
});
//翻页调用
function PageCallback(index,jq) {
InitTable(index);
console.log(index);//打印看一下当前页索引是否正确，主要就是依据索引在php中使用limit获取数据
}
//请求数据
function InitTable(pageIndex) {
$.ajax({
type: "POST",
dataType: "text",
url: 'url', //提交到php页面请求数据
data: "pageIndex=" + (pageIndex+1) + "&pageSize=" + pageSize,
//提交两个参数：pageIndex(页面索引)，pageSize(显示条数)
success: function(data) {
//在此处理php返回的数据 在php中需处理条数
if ($param['page']) { $page=(($param['page']-1)*ITEMS_PER_PAGES).','.ITEMS_PER_PAGES; } else { $page='0,'.ITEMS_PER_PAGES; } }
});
}
});
.pagination a{
padding:5px 10px;
border-radius:10px;
background-color:#ccc;
}
.current{
padding:5px 10px;
border-radius:10px;
background-color:red;
color:#fff;
}
.prev,.next{
background-color: #ccc!important;
color:#000;
}
其中的参数：
参数 描述 maxentries 总条目数 必选参数，整数 items_per_page 每页显示的条目数 可选参数，默认是10 num_display_entries 连续分页主体部分显示的分页条目数 可选参数，默认是10 current_page 当前选中的页面 可选参数，默认是0，表示第1页 num_edge_entries 两侧显示的首尾分页的条目数 可选参数，默认是0 link_to 分页的链接 字符串，可选参数，默认是"#" prev_text “前一页”分页按钮上显示的文字 字符串参数，可选，默认是"Prev" next_text “下一页”分页按钮上显示的文字 字符串参数，可选，默认是"Next" ellipse_text 省略的页数用什么文字表示 可选字符串参数，默认是"…" prev_show_always 是否显示“前一页”分页按钮 布尔型，可选参数，默认为true，即显示“前一页”按钮 next_show_always 是否显示“下一页”分页按钮 布尔型，可选参数，默认为true，即显示“下一页”按钮 callback 回调函数当点击链接的时候此函数被调用，此函数接受两个参数，新一页的id和pagination容器(一个DOM元素)。如果回调函数返回false，则pagination事件停止执行
