ASP.NET MVC+Bootstrap个人博客之后台dataTable数据列表(五)
jQuery dataTables 插件是一个优秀的表格插件,是后台工程师的福音!它提供了针对数据表格的排序、浏览器分页、服务器分页、查询、格式化等功能。dataTables 官网也提供了大量的演示和详细的文档进行说明,为了方便使用,这里进行详细说明。
去官网:https://www.datatables.net/ 下载最新版本是v1.10.12。
在页面引入:
<link rel="stylesheet" href="~/Content_Admin/css/bootstrap.min.css" /> <link rel="stylesheet" href="~/Content_Admin/css/bootstrap-responsive.min.css" /> <script type="text/javascript" src="~/Content_Admin/js/jquery.min.js"></script> <script type="text/javascript" src="~/Content_Admin/js/bootstrap.min.js"></script> <script type="text/javascript" src="~/Content_Admin/js/jquery.dataTables.min.js"></script>
HTML代码: 写上<thead></thead>标头即可
<div class="widget-content nopadding"> <table id="archives-table" class="table table-bordered data-table mydatatable"> <thead> <tr> <th>编号</th> <th>标题</th> <th>所属类别</th> <th>浏览量</th> <th>评论量</th> <th>点赞量</th> <th>状态</th> <th>操作</th> <th>操作</th> <th>操作</th> </tr> </thead> <tbody></tbody> </table> </div>
客户端jQuery:
$('#archives-table').dataTable({ "oLanguage": { //国际化 "sProcessing": "<img src='/Content_Admin/img/spinner.gif'> 努力加载数据中...", "sLengthMenu": "每页显示 _MENU_ 条结果", "sZeroRecords": "没有匹配结果", "sInfo": "总共_PAGES_ 页,显示第_START_ 到第 _END_ ,筛选之后得到 _TOTAL_ 条,初始_MAX_ 条 ", "infoEmpty": "0条记录", //筛选为空时左下角的显示" "sInfoEmpty": "没有数据", "sInfoFiltered": "(从_MAX_条数据中检索)",//筛选之后的左下角筛选提示, "sZeroRecords": "没有检索到数据", //"sSearch": '<span class="label label-success"> 搜索 </span>' }, //"bServerSide": false, //第一种场景:服务端一次性取出所有数据,完全由客户端来处理这些数据.此时为false "bServerSide": true, //第二种场景:服务端处理分页后数据,客户端呈现,此时为true.但此时aoColumns要变,将'sName'换成mDataProp,同时自定义列也要有对应的数据 "sServerMethod": "GET", "sAjaxSource": "/Admin/AdminArchives/GetArchivesJson", //ajax Url地址 "bProcessing": true, "bPaginate": true, "sPaginationType": "full_numbers", "bJQueryUI": true, //客户端传给服务器的参数为sSearch 'bFilter': false, //'bsearch':true, 'bLengthChange': true, 'aLengthMenu': [ [5, 15, 20, -1], [5, 15, 20, "全部"] // change per page values here ], 'iDisplayLength': 7, //每页显示10条记录 'bAutoWidth': true, "scrollX": true, "aoColumns": [ { "sWidth": "5%", "mDataProp": "Id" }, { "sWidth": "40%", "mDataProp": "Title", "mRender": function (data, type, row) { return '<a href="/Archives/Index/' + row.Id + '\">' + data + '</a>'; } }, { "sWidth": "10%", "mDataProp": "CategoryName" }, { "sWidth": "6%", "mDataProp": "ViewCount", "bStorable": true }, { "sWidth": "6%", "mDataProp": "CommentCount", "bStorable": true }, { "sWidth": "6%", "mDataProp": "Digg", "bStorable": true }, { "sWidth": "6%", "mDataProp": "Status", "mRender": function (data, type, row) { var value = "已发布"; if (data == "0") value = "禁用"; return value; } }, { //自定义列 : 启用/禁用 "mDataProp": "null", "sWidth": "6%", "bSearchable": false, "bStorable": false, "mRender": function (data, type, row) { var actionstr = '<a id="publicarticle" class="publicaction" target-id="' + row.Id + '" href="#">发 布</a>'; if (row.Status == "1") actionstr = '<a id="delarticle" class="delaction" target-id="' + row.Id + '" href="#">禁 用</a>'; return actionstr; } }, { //自定义列 : real删除 "mDataProp": "null", "sWidth": "6%", "bSearchable": false, "bStorable": false, "mRender": function (data, type, row) { return '<a id="realdelarticle" class="tip" target-id="' + row.Id + '" href="#"><i class="icon-remove"></i></a>'; } }, { //自定义列:编辑 "mDataProp": "null", "sWidth": "6%", "bSearchable": false, "bStorable": false, "mRender": function (data, type, row) { return '<a class="tip" href="/Admin/AdminArchives/EditArchive/' + row.Id + '"><i class="icon-pencil"></i></a>'; } } ], "aoColumnDefs": [ { //报错:DataTables warning : Requested unknown parameter '1' from the data source for row 0 //加上这段定义就不出错了。 sDefaultContent: '', aTargets: ['_all'] } ] });
Jquery.DataTables插件的两种应用场景
场景一:服务端一次性取出所有数据,完全由客户端来处理这些数据.此时"bServerSide": false,
服务端代码:
1 public JsonResult GetArchivesJson(jqDataTableParameter tableParam) 2 { 3 #region 1.0 场景一 4 ////1. 获取所有文章 5 //List<Article> DataSource = articleService.GetDataListBy(a => true, a => a.Id); 6 ////2. 构造aaData 7 //var data = DataSource.Select(a => new object[]{ 8 // a.Id, 9 // a.Title+ " ("+a.SubTime.ToString()+")", 10 // (categoryService.GetDataListBy(c=>c.Id==a.CategoryId)[0]).Name, 11 // a.ViewCount, 12 // commentService.GetDataListBy(c=>c.CmtArtId==a.Id).Count, 13 // a.Digg, 14 // a.Status==1?"正常":"删除" 15 //}); 16 ////3. 返回json,aaData是一个数组,数组里面还是字符串数组 17 //return Json(new 18 //{ 19 // sEcho = 1, 20 // iTotalRecords = DataSource.Count, 21 // iTotalDisplayRecords = data.Count(), 22 // aaData = data 23 //}, JsonRequestBehavior.AllowGet); 24 #endregion 25 }
场景二:服务端处理分页后数据,客户端呈现,此时为true,
服务端代码:
1 public JsonResult GetArchivesJson(jqDataTableParameter tableParam) 2 { 3 #region 2.0 场景二 4 //客户端需要"bServerSide": true, 用mDataProp绑定字段,obj.aData.Id获取字段(.属性) 5 6 //0.0 全部数据 7 List<Article> DataSource = articleService.GetDataListBy(a => true); 8 //DataSource = DataSource.OrderByDescending(a => a.SubTime).ToList(); 9 10 //1.0 首先获取datatable提交过来的参数 11 string echo = tableParam.sEcho; //用于客户端自己的校验 12 int dataStart = tableParam.iDisplayStart;//要请求的该页第一条数据的序号 13 int pageSize = tableParam.iDisplayLength == -1 ? DataSource.Count : tableParam.iDisplayLength;//每页容量(=-1表示取全部数据) 14 string search = tableParam.sSearch; 15 16 //2.0 根据参数(起始序号、每页容量、参训参数)查询数据 17 if (!String.IsNullOrEmpty(search)) 18 { 19 var data = DataSource.Where(a => a.Title.Contains(search) || 20 a.Keywords.Contains(search) || 21 a.Contents.Contains(search)) 22 .Skip<Article>(dataStart) 23 .Take(pageSize) 24 .Select(a => new 25 { 26 Id = a.Id, 27 Title = a.Title + " (" + a.SubTime.ToString() + ")", 28 CategoryName = a.Category.Name, 29 ViewCount = a.ViewCount, 30 CommentCount = commentService.GetDataListBy(c => c.CmtArtId == a.Id).Count, 31 Digg = a.Digg, 32 Status = a.Status 33 }).ToList(); 34 35 //3.0 构造datatable所需要的数据json对象...aaData里面应是一个二维数组:即里面是一个数组[["","",""],[],[],[]] 36 return Json(new 37 { 38 sEcho = echo, 39 iTotalRecords = DataSource.Count(), 40 iTotalDisplayRecords = DataSource.Count(), 41 aaData = data 42 }, JsonRequestBehavior.AllowGet); 43 } 44 else 45 { 46 var data = DataSource.Skip<Article>(dataStart) 47 .Take(pageSize) 48 .Select(a => new 49 { 50 Id = a.Id, 51 Title = a.Title + " (" + a.SubTime.ToString() + ")", 52 CategoryName = a.Category.Name, 53 ViewCount = a.ViewCount, 54 CommentCount = commentService.GetDataListBy(c => c.CmtArtId == a.Id).Count, 55 Digg = a.Digg, 56 Status = a.Status 57 }).ToList(); 58 59 //3.0 构造datatable所需要的数据json对象...aaData里面应是一个二维数组:即里面是一个数组[["","",""],[],[],[]] 60 return Json(new 61 { 62 sEcho = echo, 63 iTotalRecords = DataSource.Count(), 64 iTotalDisplayRecords = DataSource.Count(), 65 aaData = data 66 }, JsonRequestBehavior.AllowGet); 67 } 68 #endregion 69 }
其中dataTables发送的参数被分装在jqDataTableParameter.cs中:
1 /// <summary> 2 /// 在服务器端,可以通过以下请求参数来获得当前客户端的操作信息 3 /// jquery $('selector').datatable()插件 参数model 4 /// </summary> 5 public class jqDataTableParameter 6 { 7 /// <summary> 8 /// 1.0 DataTable用来生成的信息 9 /// </summary> 10 public string sEcho { get; set; } 11 12 /// <summary> 13 /// 2.0分页起始索引 14 /// </summary> 15 public int iDisplayStart { get; set; } 16 17 /// <summary> 18 /// 3.0每页显示的数量 19 /// </summary> 20 public int iDisplayLength { get; set; } 21 22 /// <summary> 23 /// 4.0搜索字段 24 /// </summary> 25 public string sSearch { get; set; } 26 27 /// <summary> 28 /// 5.0列数 29 /// </summary> 30 public int iColumns { get; set; } 31 32 /// <summary> 33 /// 6.0排序列的数量 34 /// </summary> 35 public int iSortingCols { get; set; } 36 37 /// <summary> 38 /// 7.0逗号分割所有的列 39 /// </summary> 40 public string sColumns { get; set; } 41 }

以上就是对datatable插件的使用说明。
