MVC异步分页代码分享_实用技巧_

 // // GET: /AjaxUser/ shopEntities shop = new shopEntities(); public ActionResult Index() { return View(); } public ActionResult loadjson() { int pageSize = Request["pageSize"] == null ? 10 : int.Parse(Request["pageSize"]); int pageIndex = Request["pageIndex"] == null ? 1 : int.Parse(Request["pageIndex"]); int totalCount = shop.tbl_admin.Count(); //给前台userinfo所有的数据，并且是json格式 var allorder = shop.tbl_admin.OrderBy(u=>u.id) .Skip(pageSize*(pageIndex-1)) .Take(pageSize) .ToList(); //接受一个对像，内部把此对象使用javaScript序列化类对象志字符串，发送到前台 var data = from u in allorder select new { u.id,u.realname,u.sex}; string strNav = PageNavHelper.ShowPageNavigate(pageIndex,pageSize,totalCount); var result = new {Data=data, NavStr=strNav }; return Json(result, JsonRequestBehavior.AllowGet); }
