Jquery+Ajax+Json分页

var pageIndex = 0; //页面索引初始值

var pageSize = 10; //每页显示条数初始化，修改显示条数，修改这里即可

$(function () {

InitTable(0); //Load事件，初始化表格数据，页面索引为0(第一页)

//分页，PageCount是总条目数，这是必选参数，其它参数都是可选

$("#Pagination").pagination(, {

callback: PageCallback,

prev_text: '上一页', //上一页按钮里text

next_text: '下一页', //下一页按钮里text

items_per_page: pageSize, //显示条数

num_display_entries: 6, //连续分页主体部分分页条目数

current_page: pageIndex, //当前页索引

num_edge_entries: 2 //两侧首尾分页条目数

});

//翻页调用

function PageCallback(index, jq) {

InitTable(index);

}

//请求数据

function InitTable(pageIndex) {

$.ajax({

type: "POST",

dataType: "json",

url: 'SupplyAJAX.aspx', //提交到一般处理程序请求数据

data: "type=show&random=" + Math.random() + "&pageIndex=" + (pageIndex + 1) + "&pageSize=" + pageSize, //提交两个参数：pageIndex(页面索引)，pageSize(显示条数)

error: function () { alert('error data'); }, //错误执行方法

success: function (data) {

$("#Result tr:gt(0)").remove(); //移除Id为Result的表格里的行，从第二行开始(这里根据页面布局不同页变)

var json = data; //数组

var html = "";

$.each(json.data, function (index, item) {

//循环获取数据

var id = item.Id;

var name = item.Name;

var sex = item.Sex;

html += "

" + id + "" + name + "" + sex + "";

});

$("#Result").append(html); //将返回的数据追加到表格

}

});

}

});
