asp.net mvc bootstrap datatable 服务端分页 更新槽糕的代码【1】
datatable 服务端分页
因项目需求变动，需处理大量数据，更改成服务端分页，自己两天的学习笔记
datatable 1.10.7 百度云下载 密码：0ea1
先上图【 jqueryui风格】
"bJQueryUI": false, //是否使用 jQury的UI theme 默认风格
查询效果

/// <summary> ///分页类处理 /// </summary> public class DataTableParameter { /// <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; } }
/// <summary> /// 临时新闻类 /// </summary> public class News { public int Id { get; set; } public string Title { get; set; } public string NewsContent { get; set; } public int DCount { get; set; } public int Status { get; set; } }
无连接数据库，通过for循环生成list数据集合，大小可以自己稍微调整
/// <summary> /// 生成数据源 /// </summary> /// <returns></returns> public List<News> Getlist() { List<News> myLsit = new List<News>(); for (int i = 0; i < 300; i++) { if (i % 2 == 0) { myLsit.Add(new News { Id = i, Title = "ceshi", NewsContent = "哈哈" + i, DCount = 20, Status = 0 }); } else { myLsit.Add(new News { Id = i, Title = "ceshi", NewsContent = "哈哈" + i, DCount = 20, Status = 1 }); } } return myLsit; }
最后是控制器
[HttpGet] public JsonResult GetNesList(DataTableParameter tp) { #region //1 获取数据源 List<News> DataSource = Getlist(); //DataSource = DataSource.OrderByDescending(a => a.SubTime).ToList(); //2 处理页数 string echo = tp.sEcho; //用于客户端自己的校验 int dataStart = tp.iDisplayStart;//开始页数 int pageSize = tp.iDisplayLength == -1 ? DataSource.Count : tp.iDisplayLength;//总页数 string search = tp.sSearch; //3 是否有搜索框条件，【因为版本问题，暂时没有实现】 if (!String.IsNullOrEmpty(search)) { var data = DataSource.Where(a => a.Title.Contains(search) || a.NewsContent.Contains(search)) .Skip<News>(dataStart) .Take(pageSize) .ToList(); return Json(new { sEcho = echo, iTotalRecords = DataSource.Count(), iTotalDisplayRecords = DataSource.Count(), aaData = data }, JsonRequestBehavior.AllowGet); } else { var data = DataSource.Skip<News>(dataStart) .Take(pageSize) .ToList(); return Json(new { sEcho = echo, iTotalRecords = DataSource.Count(), iTotalDisplayRecords = DataSource.Count(), aaData = data }, JsonRequestBehavior.AllowGet); } #endregion }
