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
先上图【 jqueryui风格】
前端代码：
@{
Layout = null;
}

////表格行点击设置选中样式
$("#archivestable tbody").on("click", "tr", function () {

else {
table.$("tr.selected").removeClass("selected");

});
});
</script>
</body>
</html>
后端：实体类
/// <summary>

{

public string Title { get; set; }
public string NewsContent { get; set; }

public string sColumns { get; set; }
}
数据源：
/// <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;
}
//控制器代码
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.Start;//开始页数
int pageSize = tp.Length == -1 ? DataSource.Count : tp.Length;//总页数
string search = tp.search;
//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

#endregion
}
第一次写，代码很糟糕
