There is a huge data stored in grid that comes from a sql query joined more than ona table. Data type is Json. I filtered data and then want to sent filtered data to controller. But how it can be?
Here is test json data in javascript block:



var jsonData = {
"FirstName": "John",
"LastName": "Doe",
"DoB": "01/01/1970" };


And this is my javascript function:



function submitForm() {
var user = jsonData;

jQuery.ajax({
type: "POST",
url: "@Url.Action("GetJsonData", "Account")",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(user),
success: function (data) { alert(data); },
failure: function (errMsg) {
alert(errMsg);
}
});
}


How to get the Json data in controller? Here is my [HttpPost] method:



    [HttpPost]
public IActionResult GetJsonData(String user)
{
//...
return null;
}


user gets null.. Should i change type "String" in method or something else?

  • is this JavaScript inside a Razor view? It needs to be, otherwise the @Url.Action won't work.

  • No, it's not about Razor View. Because i point a breakpoint for GetJsonData method, and the method works...

Since user is a string, you could try to create an object with a property user:



jQuery.ajax({
type: "POST",
url: "@Url.Action("GetJsonData", "Account")",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: {
user: JSON.stringify(user)
},
success: function (data) { alert(data); },
failure: function (errMsg) {
alert(errMsg);
}
});




Or using FormData:



var formData = new FormData();
formData.append('user', JSON.stringify(user));

jQuery.ajax({
type: "POST",
url: "@Url.Action("GetJsonData", "Account")",
contentType: false,
processData: false,
data: formData,
success: function (data) { alert(data); },
failure: function (errMsg) {
alert(errMsg);
}
});
