• 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

    <script>
    $(function () {
    //提示信息
    var lang = {
    "sProcessing": "处理中...",
    "sLengthMenu": "每页 _MENU_ 项",
    "sZeroRecords": "没有匹配结果",
    "sInfo": "当前显示第 _START_ 至 _END_ 项,共 _TOTAL_ 项。",
    "sInfoEmpty": "当前显示第 0 至 0 项,共 0 项",
    "sInfoFiltered": "(由 _MAX_ 项结果过滤)",
    "sInfoPostFix": "",
    "sSearch": "搜索:",
    "sUrl": "",
    "sEmptyTable": "表中数据为空",
    "sLoadingRecords": "载入中...",
    "sInfoThousands": ",",
    "oPaginate": {
    "sFirst": "首页",
    "sPrevious": "上页",
    "sNext": "下页",
    "sLast": "末页",
    "sJump": "跳转"
    },
    "oAria": {
    "sSortAscending": ": 以升序排列此列",
    "sSortDescending": ": 以降序排列此列"
    }
    };

    //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

    <table id="example" class="display" cellspacing="0" width="100%">
    <thead>
    <tr>
    <th>Id</th>
    <th>姓名</th>
    <th>年龄</th>
    </tr>
    </thead>
    <tfoot>
    <tr>
    <th>Id</th>
    <th>姓名</th>
    <th>年龄</th>
    </tr>
    </tfoot>
    </table>

    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 = 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 = 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
