利用ASP.NET MVC和Bootstrap快速搭建个人博客之后台dataTable数据列表

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

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:

public JsonResult GetArchivesJson(jqDataTableParameter tableParam)
{
#region 1.0 场景一
////1. 获取所有文章
//ListArticle> DataSource = articleService.GetDataListBy(a => true, a => a.Id);
////2. 构造aaData
//var data = DataSource.Select(a => new object[]{
// a.Id,
// a.Title+ " ("+a.SubTime.ToString()+")",
// (categoryService.GetDataListBy(c=>c.Id==a.CategoryId)[0]).Name,
// a.ViewCount,
// commentService.GetDataListBy(c=>c.CmtArtId==a.Id).Count,
// a.Digg,
// a.Status==1?"正常":"删除"
//});
////3. 返回json,aaData是一个数组，数组里面还是字符串数组
//return Json(new
//{
// sEcho = 1,
// iTotalRecords = DataSource.Count,
// iTotalDisplayRecords = data.Count(),
// aaData = data
//}, JsonRequestBehavior.AllowGet); 
#endregion
}
public JsonResult GetArchivesJson(jqDataTableParameter tableParam)

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:

public JsonResult GetArchivesJson(jqDataTableParameter tableParam)
{
#region 2.0 场景二
//客户端需要"bServerSide": true, 用mDataProp绑定字段,obj.aData.Id获取字段(.属性)
//0.0 全部数据
ListArticle> DataSource = articleService.GetDataListBy(a => true);
//DataSource = DataSource.OrderByDescending(a => a.SubTime).ToList();
//1.0 首先获取datatable提交过来的参数
string echo = tableParam.sEcho; //用于客户端自己的校验
int dataStart = tableParam.iDisplayStart;//要请求的该页第一条数据的序号
int pageSize = tableParam.iDisplayLength == -1 ? DataSource.Count : tableParam.iDisplayLength;//每页容量（=-1表示取全部数据）
string search = tableParam.sSearch;
//2.0 根据参数(起始序号、每页容量、参训参数)查询数据
if (!String.IsNullOrEmpty(search))
{
var data = DataSource.Where(a => a.Title.Contains(search) ||
a.Keywords.Contains(search) ||
a.Contents.Contains(search))
.SkipArticle>(dataStart)
.Take(pageSize)
.Select(a => new
{
Id = a.Id,
Title = a.Title + " (" + a.SubTime.ToString() + ")",
CategoryName = a.Category.Name,
ViewCount = a.ViewCount,
CommentCount = commentService.GetDataListBy(c => c.CmtArtId == a.Id).Count,
Digg = a.Digg,
Status = a.Status
}).ToList();
//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[["","",""],[],[],[]]
return Json(new
{
sEcho = echo,
iTotalRecords = DataSource.Count(),
iTotalDisplayRecords = DataSource.Count(),
aaData = data
}, JsonRequestBehavior.AllowGet);
}
else
{
var data = DataSource.SkipArticle>(dataStart)
.Take(pageSize)
.Select(a => new
{
Id = a.Id,
Title = a.Title + " (" + a.SubTime.ToString() + ")",
CategoryName = a.Category.Name,
ViewCount = a.ViewCount,
CommentCount = commentService.GetDataListBy(c => c.CmtArtId == a.Id).Count,
Digg = a.Digg,
Status = a.Status
}).ToList();
//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[["","",""],[],[],[]]
return Json(new
{
sEcho = echo,
iTotalRecords = DataSource.Count(),
iTotalDisplayRecords = DataSource.Count(),
aaData = data
}, JsonRequestBehavior.AllowGet);
}
#endregion
}
public JsonResult GetArchivesJson(jqDataTableParameter tableParam)

其中dataTables发送的参数被分装在jqDataTableParameter.cs中：

/// summary>
/// 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
/// jquery $('selector').datatable()插件 参数model
/// /summary>
public class jqDataTableParameter
{
/// summary>
/// 1.0 DataTable用来生成的信息
/// /summary> 
public string sEcho { get; set; }
/// summary>
/// 2.0分页起始索引
/// /summary>
public int iDisplayStart { get; set; }
/// summary>
/// 3.0每页显示的数量
/// /summary>
public int iDisplayLength { get; set; }
/// summary>
/// 4.0搜索字段
/// /summary>
public string sSearch { get; set; }
/// summary>
/// 5.0列数
/// /summary>
public int iColumns { get; set; }
/// summary>
/// 6.0排序列的数量
/// /summary>
public int iSortingCols { get; set; }
/// summary>
/// 7.0逗号分割所有的列
/// /summary>
public string sColumns { get; set; }
}
public class jqDataTableParameter
