while unpacking json in Ajax I ran into an error
Uncaught TypeError: Cannot read properties of undefined (reading 'GrossSalesPriceForUser')
in controller i have class, i create object and i sent values to new object i want to sent it to view now
Controller
public class CalsEarlyStatementForUser
{
public decimal GrossSalesPriceForUser { get; set; }
public decimal PaidBeneficiaryForUser { get; set; }
}
//(...)
//method
CalsEarlyStatementForUser objCalsEarlyStatementForUser = new CalsEarlyStatementForUser();
objCalsEarlyStatementForUser.GrossSalesPriceForUser = grossSalesPriceForUser;
objCalsEarlyStatementForUser.PaidBeneficiaryForUser = paidBeneficiaryForUser;
var jsonData = JsonConvert.SerializeObject(objCalsEarlyStatementForUser);
return Json(jsonData);
}
View
$.ajax({
url: "@Url.Action("CalcEarlyStatement", "Calculations")",
type: "GET",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: {"data": JSON.stringify(data)},
cache: false,
success: function (result) {
// it dont work
$("#GrossSalesPriceForUser")
.dxNumberBox("instance")
.option("value", result.objCalsEarlyStatementForUser.GrossSalesPriceForUser);
$("#PaidBeneficiaryForUser")
.dxNumberBox("instance")
.option("value", result.objCalsEarlyStatementForUser.PaidBeneficiaryForUser);
},
failure: function (error) {
alert(error);
},
error: function (error) {
alert(error);
}
});
These lines are redundant:
var jsonData = JsonConvert.SerializeObject(objCalsEarlyStatementForUser);
return Json(jsonData);
As a result, you're not returning an object, but merely a JSON string. So the result variable in your client-side code is just a string and has no objCalsEarlyStatementForUser property. You'd have to deserialize the string client-side to get the object.
Instead, just return the object itself:
return Json(objCalsEarlyStatementForUser);
The server-side framework will handle serializing it over the wire for you, and the client-side framework will handle deserializing it from the response for you. Otherwise, if you double-serialize it on the server, you'd need to double-deserialize it on the client.
