mvc中ajax,c# – 在Mvc中对控制器进行简单的Ajax调用
我是mvc的新手,我尝试对我的控制器进行简单的Ajax调用,因此我可以在创建视图中使用日期和时间选择器.
当我在IE中使用调试时,我收到此错误消息,但如果我执行断点,看起来我得到了正确的数据.
The parameters dictionary contains a null entry for parameter ‘Lokal’ of non-nullable type ‘System.Int32’ for method
‘System.Web.Mvc.ActionResult CreateEvent(System.String, System.String,
System.String, Int32)’ in
‘VLVision.Controllers.SammantradesAdminController’. An optional
parameter must be a reference type, a nullable type, or be declared as
an optional parameter.
Parameternamn: parameters
HTML
script type="text/javascript">
function createSammantrade() {
var sammantrade = document.getElementById('sammantrade').value;
var date = document.getElementById('datepicker').value;
var startTime = date + ' ' + document.getElementById('StartTimepicker').value;
var endTime = date + ' ' + document.getElementById('EndTimepicker').value;
var lokal = document.getElementById('lokal').value;
$.ajax({
url: "@Url.Action("CreateEvent", "SammantradesAdmin")",
data: { createSammantrade: sammantrade, createStartTime: startTime, createEndTime: endTime, createLokal: lokal },
type: "POST",
error: function () {
alert("An error occurred.");
},
success: function (data) {
$("#clanderDiv").html(data);
$("#setEventResponse").html("Händelse sparad");
// $(".blank").tooltip();
}
});
}

public ActionResult Create()
{
ViewBag.lID = new SelectList(db.Lokal, "lID", "lLokal");
return View();
}
[HttpPost]
public ActionResult CreateEvent(string createSammantrade, string createStartTime, string createEndTime, int Lokal)
{
Sammantrade sammantrade = new Sammantrade();
sammantrade.sSammantrade = createSammantrade;
sammantrade.sStartTid = Convert.ToDateTime(createStartTime);
sammantrade.sSlutTid = Convert.ToDateTime(createEndTime);
sammantrade.lID = Lokal;
if (ModelState.IsValid)
{
db.Sammantrade.Add(sammantrade);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.lID = new SelectList(db.Lokal, "lID", "lLokal", sammantrade.lID);
return View(sammantrade);
