上回说到jqgrid的基本配置，同时演示了显示数据的一种方法——datatype: "local"。这种方法是从本地获取的，确切地说是在前端页面的javascript里写的硬编码。
本回说到的也是一种硬编码，只不过是在后台的Controller里写的，也是一种快速演示的方法，我们用ArrayList来填充数据。同时，jqgrid里要使用url参数以指定是从哪个action获得数据。
View：
1 @{ 2 ViewBag.Title = "GetDataFromLocal"; 3 } 4 5 GetDataFromLocal
6 7 28 29 Controller：
1 public ActionResult GetDataFromLocal() 2 { 3 return View(); 4 } 5 6 public JsonResult GetData(int? page, int? rows) 7 { //把数据放到一个动态数组里 8 ArrayList list = new ArrayList(); 9 list.Add(new { id = "1", invdate = "2007-10-01", name = "test" });10 list.Add(new { id = "2", invdate = "2007-10-02", name = "test" });11 list.Add(new { id = "3", invdate = "2007-10-02", name = "test" });12 list.Add(new { id = "4", invdate = "2007-10-02", name = "test" });13 list.Add(new { id = "5", invdate = "2007-10-02", name = "test" });14 list.Add(new { id = "6", invdate = "2007-10-02", name = "test" });15 list.Add(new { id = "7", invdate = "2007-10-02", name = "test" });16 list.Add(new { id = "8", invdate = "2007-10-02", name = "test" });17 list.Add(new { id = "9", invdate = "2007-10-02", name = "test" });18 list.Add(new { id = "10", invdate = "2007-10-02", name = "test" });19 list.Add(new { id = "11", invdate = "2007-10-02", name = "test" });20 list.Add(new { id = "12", invdate = "2007-10-02", name = "test" });21 22 var myData = list.ToArray();//便于下面用linq分页23 24 //jqgrid的参数25 int pageNum = page.HasValue ? page.Value : 1;//当前显示哪一页26 int pageSize = rows.HasValue ? rows.Value : 10; //每一页显示多少条记录27 int totalRecords = list.Count;//总记录数28 int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);//总页数29 var jsonData = new30 {31 total = totalPages,32 page = pageNum,33 records = totalRecords,34 rows = myData.Skip((pageNum - 1) * pageSize).Take(pageSize)//分页35 };36 37 return Json(jsonData, JsonRequestBehavior.AllowGet);38 }
