页面相关位置调用

<!--在控制器里面存储的ViewData，totalRecord表示根据添加查询到的数据并返回的条数，parameter表示搜索条件（关键字搜索等等）-->

@Html.PageNavigate(int.Parse(ViewData["pageIndex"].ToString()),int.Parse(ViewData["pageSize"].ToString()),int.Parse(ViewData["totalRecord"].ToString()),ViewData["parameter"].ToString())

控制器相关方法实现

例:

public Action Moment(int pageIndex=,int pageSize=)

{

int totalRecord =;

List<Aniuge_Moments> lam =MomentsBussiness.GetInstance().GetMoment(pageSize,pageIndex,out totalRecord);//获取分页显示的列表

ViewData["totalRecord"]=totalRecord;

ViewData["pageIndex"]=pageIndex;

ViewData["pageSize"]=pageSize;

#region 生成搜索状态保持数据

StringBuilder sb =new StringBuilder ();

foreach(string item in Request.QueryString.Allkeys)

{

if(!item.Equals("pageIndex")&&!item.Equls("pageSize"))

sb.Append(item + "=" +Request.QueryString[item]+"&");

}

ViewData["parameter"]=sb.Tostring().Trim("&");

#endregion

return View(lam);

}

要无刷新分页及更多功能  看“轻量级表格插件Bootstrap Table。拥有强大的支持固定表头、单/复选、排序、分页、搜索及自定义表头等功能。”这便随笔
