datatables后台分页例子(可直接复制代码)

1.head表签引用

这两个文件即可

2.复制下面的代码到webform中的head标签中

//初始化表格
var table = $("#example").dataTable({
language: lang, //提示信息
bSort: true,
autoWidth: false, //禁用自动调整列宽
stripeClasses: ["odd", "even"], //为奇偶行加上样式，兼容不支持CSS伪类的场合
processing: true, //隐藏加载提示,自行处理
serverSide: true, //启用服务器端分页
//aoColumnDefs: [
// { "bSortable": false, "aTargets": [0] }
//],
searching: true, //是否禁用原生搜索(false为禁用,true为使用)
orderMulti: false, //启用多列排序
order: [], //取消默认排序查询,否则复选框一列会出现小箭头
renderer: "bootstrap", //渲染样式：Bootstrap和jquery-ui
pagingType: "full_numbers", //分页样式：simple,simple_numbers,full,full_numbers
bScrollInfinite: true,
columnDefs: [{
"targets": 'nosort', //列的样式名
"orderable": false //包含上样式名‘nosort’的禁止排序
}],
ajax: function (data, callback, settings) {
//封装请求参数
var param = {};
param.limit = data.length;//页面显示记录条数，在页面显示每页显示多少项的时候
param.start = data.start;//开始的记录序号
param.page = (data.start / data.length) + 1;//当前页码
param.search = data.search.value;//搜索条件
if (data.order.length > 0) {
param.order = data.columns[data.order[0].column].data;
param.dir = data.order[0].dir;
}
console.log(param);
//ajax请求数据
$.ajax({
type: "GET",
url: "/WebForm1.aspx?Action=LoadDataList",
cache: false, //禁用缓存
data: param, //传入组装的参数
dataType: "json",
success: function (result) {
//console.log(result);
//setTimeout仅为测试延迟效果
setTimeout(function () {
//封装返回数据
var returnData = {};
returnData.draw = data.draw;//这里直接自行返回了draw计数器,应该由后台返回
returnData.recordsTotal = result.total;//返回数据全部记录
returnData.recordsFiltered = result.total;//后台不实现过滤功能，每次查询均视作全部结果
returnData.data = result.data;//返回的数据列表
console.log(returnData);
//调用DataTables提供的callback方法，代表数据已封装完成并传回DataTables进行渲染
//此时的数据需确保正确无误，异常判断应在执行此回调前自行处理完毕
callback(returnData);
}, 200);
}
});
},
//列表表头字段
columns: [
{ "data": "Id" },
{ "data": "Name" },
{ "data": "Age" }
]
}).api();
//此处需调用api()方法,否则返回的是JQuery对象而不是DataTables的API对象
});
</script>

3.在form标签中复制以下代码

4.在webform后台中复制以下代码

string action = Request.Params["Action"];
if (!string.IsNullOrEmpty(action) && action.Equals("LoadDataList"))
{
int page = !string.IsNullOrEmpty(Request.Params["page"]) ? Convert.ToInt32(Request.Params["page"]) : 1;
int limit = !string.IsNullOrEmpty(Request.Params["limit"]) ? Convert.ToInt32(Request.Params["limit"]) : 1;
int start = !string.IsNullOrEmpty(Request.Params["start"]) ? Convert.ToInt32(Request.Params["start"]) : 0;
//搜索的条件
string search = Request.Params["search"];
//排序的字段名称
string order = Request.Params["order"];
//排序类型
string dir = Request.Params["dir"];

#region 获取符合查询条件的数据集合
List<Student> listData = new List<Student>();
for (int i = 0; i < list.Count; i++)
{
if (string.IsNullOrEmpty(search))
{
listData.Add(list[i]);
}
else
{
if (list[i].Name.Contains(search))
{
listData.Add(list[i]);
}
}
}
#endregion
//排序,我这里写死了根据名称排序
if (!string.IsNullOrEmpty(order) && !string.IsNullOrEmpty(dir))
{
if (dir.Equals("asc"))
{
listData = listData.OrderBy(a => a.Name).ToList();
}
else
{
listData = listData.OrderByDescending(a => a.Name).ToList();
}
}

//获取datatables要查询几条数据的数据集合
List<Student> listData1 = new List<Student>();
for (int i = (page - 1) * limit; i < page * limit; i++)
{
if (i >= listData.Count)
{
break;
}
listData1.Add(listData[i]);
}
var data1 = new
{
total = listData.Count,
page = 5,
limit = 10,
data = listData1
};
string jsonData = JsonConvert.SerializeObject(data1);
Response.Write(jsonData);
Response.End();
}

5.在方法外面添加一个这样的集合

List<Student> list = new List<Student>() {
new Student(){ Id = 1, Name = "彭文峰", Age = 20 },
new Student(){ Id = 2, Name = "李宝明", Age = 22 },
new Student(){ Id = 3, Name = "赖道兴", Age = 24 },
new Student(){ Id = 4, Name = "唐静", Age = 23 },
new Student(){ Id = 5, Name = "李团全", Age = 21 },

new Student(){ Id = 6, Name = "蒙志英", Age = 20 },
new Student(){ Id = 7, Name = "钟志敏", Age = 22 },
new Student(){ Id = 8, Name = "彭永庆", Age = 24 },
new Student(){ Id = 9, Name = "戴曦", Age = 23 },
new Student(){ Id = 10, Name = "韦宗辰", Age = 21 },

new Student(){ Id = 11, Name = "彭宇云", Age = 20 },
new Student(){ Id = 12, Name = "钟善贵", Age = 22 },
new Student(){ Id = 13, Name = "邱明明", Age = 24 },
new Student(){ Id = 14, Name = "黄吉良", Age = 23 },
new Student(){ Id = 15, Name = "梁辉杰", Age = 21 }
};

基本上就OK了
唯一要改估计就是那个ajax请求的路径了
