我有一个网格和一个打开表单的操作按钮。网格和表单上有一个不可编辑的日期字段 - 但是当我执行updateRecord时，数据字段值在网格中设置为null。
我注意到两件事 - 在ext-all中 - 当解析日期时 - 它不被识别为日期，而是字符串，所以当它被解析时，它应该是以ms为单位 - 但实际上是'yyyy-mm-dd'格式。因此解析返回null - 这就是发送到网格的内容。
有任何想法如何绕过这个并返回实际日期？
感谢。
这是我的index.cshtml
<script type="text/javascript">

这是GridPanel：

控制器：
public class HomeController : Controller

public ActionResult Index()

ViewBag.Message = "Welcome to ASP.NET MVC!";
return View();
}
[AcceptVerbs(HttpVerbs.Get)]
[ActionName("ActionsGrid")]
public ActionResult GetActionsGrid()
{
DetailsViewModel model = new DetailsViewModel();
List<ExtJsTreeGrid.Models.ActionGrid> ActionsFromDB = model.GetActionsGrid();
model.transaction = ActionsFromDB;
model.success = true;
return Json(model, JsonRequestBehavior.AllowGet);
}
}
型号：
public class ActionGrid
{
public Int32 Id { get; set; }
public bool Approval { get; set; }
public string ErrorComment { get; set; }
public string ErrorSource { get; set; }
public DateTime RecordDate { get; set; }
}
public class DetailsViewModel
{
public List<ActionGrid> transaction = new List<ActionGrid>();
public bool success = true;
public List<ActionGrid> GetActionsGrid()
{
return new List<ActionGrid> {
new ActionGrid { Id = 1,
Approval = true,
ErrorComment = string.Empty,
ErrorSource = string.Empty,
RecordDate = new DateTime(1979, 11, 23)
},
new ActionGrid { Id = 2,
Approval = true,
ErrorComment = string.Empty,
ErrorSource = string.Empty,
RecordDate = new DateTime(1980, 05, 20)
},
new ActionGrid { Id = 3,
Approval = true,
ErrorComment = string.Empty,
ErrorSource = string.Empty,
RecordDate = new DateTime(1995, 01, 12)
},
new ActionGrid { Id = 4,
Approval = true,
ErrorComment = string.Empty,
ErrorSource = string.Empty,
RecordDate = new DateTime(2010, 09, 02)
}};
}
}
EDIT: I added a check for value being already a date, to ext-all to date conversion function. Is there a better way?
DATE: {
convert: function (v) {
var df = this.dateFormat,
parsed;
if (!v) {
return null;
}
if (Ext.isDate(v)) {
return v;
}
**try {
var myDate = new Date(v);
if (Ext.isDate(myDate) == true && isNaN(myDate) == false && myDate != undefined)
return myDate;
}
catch (ex) {
}**
if (df) {
if (df == 'timestamp') {
return new Date(v * 1000);
}
if (df == 'time') {
return new Date(parseInt(v, 10));
}
return Ext.Date.parse(v, df);
}
parsed = Date.parse(v);
return parsed ? new Date(parsed) : null;
},
sortType: st.asDate,
type: 'date'
}
