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>

                            </tr>

jQuery

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        }
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:

 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) ||

22                      .Skip<Article>(dataStart)
