MVC controller method is not being called from ajax

Question

MVC controller method is not being called from the ajax i have declared. PFB the code snippet C# Controller:

public ActionResult Checkfunction(string ReqID, string AssociateId, string AssetId)
{
      MyDetails obj = new MyDetails();
      List<string> Lst = new List<string>();
      Lst = obj.Check(AssociateId, AssetId, ReqID);
      return this.Json(Lst, "text/json");
}

Javascript code (ajax call): refering details controller, and webmethod Checkfunction

$.ajax({
    type: 'GET',
    cache: false,
    url: '@Url.Action("Details/Checkfunction")',
    data: { 'ReqID': RequestId, 'AssociateId': AssociateID, 'AssetId': Host_Name },
    contentType: "application/json",
    success: function (data) {
        debugger;
        if (data.length > 0) {

                ViewModel.REQUESTID() = data[0];
                ViewModel.FLAG() = '1';
        }
        else {
            debugger;
            ViewModel.FLAG() = '0';
            ViewModel.REQUESTID() = '';
        }

        if (ViewModel.REQUESTID() != '' || ViewModel.REQUESTID() != null) {
            debugger;
            ViewModel.REQID() = RequestId;
        }
    },

    error: function (error) {
        alert("error");
    }
});

your ajax url is pointed to PhoenixInbox/CheckMSDNRemap, but your method is Checkfunction? That would be a good starting point — Jonesopolis

simply change the url properties to url: '/PhoenixInbox/Checkfunction' — Mahbubur Rahman Manik

Try this:

$.ajax({
type: 'POST',
cache: false,
url: '/PhoenixInbox/Checkfunction',
data: { 'ReqID': RequestId, 'AssociateId': AssociateID, 'AssetId': Host_Name },
contentType: "application/json",
success: function (data) {
    debugger;
    if (data.length > 0) {

            ViewModel.REQUESTID() = data[0];
            ViewModel.FLAG() = '1';
    }
    else {
        debugger;
        ViewModel.FLAG() = '0';
        ViewModel.REQUESTID() = '';
    }

    if (ViewModel.REQUESTID() != '' || ViewModel.REQUESTID() != null) {
        debugger;
        ViewModel.REQID() = RequestId;
    }
},

error: function (error) {
    alert(JSON.stringify(error));
}
});

Controller:

[Httppost]
public ActionResult Checkfunction(string ReqID, string AssociateId, string AssetId)
{
      MyDetails obj = new MyDetails();
      List<string> Lst = new List<string>();
      Lst = objMyAssetsDetails.Check(AssociateId, AssetId, ReqID);
      return this.Json(Lst, "text/json");
}

'/PhoenixInbox/Checkfunction' could blow up in production if the app is not deployed in root directory. So the url should be built with 'Url.Action' at runtime.

nowadays it's better to use promises, and if you're going to return json, it's better return JsonResult instead of ActionResult

Build the url correctly:

$.ajax({ type: 'POST', cache: false, url: '@Url.AbsoluteAction("PhoenixInbox", "Checkfunction")',
Make sure you allow get on Get action: JsonRequestBehavior.AllowGet

public ActionResult Checkfunction(string ReqID, string AssociateId, string AssetId) { MyDetails obj = new MyDetails(); List Lst = new List(); Lst = objMyAssetsDetails.Check(AssociateId, AssetId, ReqID); return this.Json(Lst, "text/json", JsonRequestBehavior.AllowGet ); }
