ASP.NET MVC 使用 Datatables (2)
在服务器端实现分页，排序，获取当前页面数据
在上篇的基础上进行改造(datatables的客户端实现)
1、修改View页面代码如下：
<div class="row"> <div class="col-md-12"> <div class="panel panel-primary" id="list-panel"> <div class="panel-heading"> <h1 class="panel-title">Assets</h1> </div> <div class="panel-body"> <table id="assets-data-table" class="table table-striped table-bordered" style="width:100%"> </table> </div> </div> </div></div>@section Scripts{ <script type="text/javascript"> var assetListVM; $(document).ready(function () { assetListVM = { dt:null, init: function () { dt = $("#assets-data-table").DataTable({ "serverSide": true, "proccessing": true, "ajax": { "url":"@Url.Action("Get","Asset")" }, "columns": [ { "title": "Bar Code", "data": "Barcode", "searchable": true }, { "title": "Manufacturer", "data": "Manufacturer", "searchable": true }, { "title": "Model", "data": "ModelNumber", "searchable": true }, { "title": "Building", "data": "Building", "searchable": true }, { "title": "Room No", "data": "RoomNo" }, { "title": "Quantity", "data": "Quantity" } ], "lengthMenu": [[10, 25, 50, 100], [10, 25, 50, 100]], "language": { "processing": "处理中...", "lengthMenu": "显示 _MENU_ 项结果", "zeroRecords": "没有匹配结果", "info": "显示第 _START_ 至 _END_ 项结果，共 _TOTAL_ 项", "infoEmpty": "显示第 0 至 0 项结果，共 0 项", "infoFiltered": "(由 _MAX_ 项结果过滤)", "infoPostFix": "", "search": "搜索:", "searchPlaceholder": "搜索...", "url": "", "emptyTable": "表中数据为空", "loadingRecords": "载入中...", "infoThousands": ",", "paginate": { "first": "首页", "previous": "上页", "next": "下页", "last": "末页" }, "aria": { paginate: { first: ‘首页‘, previous: ‘上页‘, next: ‘下页‘, last: ‘末页‘ }, "sortAscending": ": 以升序排列此列", "sortDescending": ": 以降序排列此列" }, "decimal": "-", "thousands": "," } }); } }; assetListVM.init(); }); </script>}2、添加服务端必须的组件：
A:Install-Package datatables.mvc5
B:Install-Package System.Linq.Dynamic
3、添加服务器端方法：
public ActionResult Get([ModelBinder(typeof(DataTablesBinder))] IDataTablesRequest requestModel) { IQueryable<Asset> query = dbContext.Assets; var totalcount = query.Count(); #region Filtering if (requestModel.Search.Value!=string.Empty) { var value = http://www.mamicode.com/requestModel.Search.Value.Trim();"," : ""; orderByString += (column.Data) + (column.SortDirection == Column.OrderDirection.Ascendant?" asc":" desc"); } query = query.OrderBy(orderByString == string.Empty ? " Barcode asc" : orderByString); #endregion //Paging query = query.Skip(requestModel.Start).Take(requestModel.Length); var data = http://www.mamicode.com/query.Select(asset=>new>4、运行程序，查看结果
