如何将绑定到视图的模型从Ajax调用中单击到控制器动作？

Question

Here is my ajax call:

$('#addNominationForm').on("submit", function (e) {
    debugger;
    e.preventDefault();
    $.ajax({
        type: 'post',
        url: '@Url.Action("AddNomination", "Nomination")',
        data: JSON.stringify({ model: model, submit: "submit" }),
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            swal({
                title: "Nominated Successfully",
                showCancelButton: false,
                confirmButtonColor: "#88a364",
                confirmButtonText: "Ok"
            },
            function () {
                if (isConfirm) {
                    window.location.href = '@Url.Action("Dashboard", "Dashboard")';
                }
            });
        },
        Error: function (xhr, status, error) {
            alert("error" + xhr.responseText)
        }
    });
});

This is action:

[HttpPost]
[CustomeAuthorize(AllowedRole = "Manager")]
public ActionResult AddNomination(NominationViewModel model, string submit)
{
    //business logic in action
}

But here when ajax call is done, in action model contains null. How can I do it?Or is there any other way to send model on view using ajax call on normal button click?

Answer 1

Dont stringify your data:

data: { model: model, submit: "submit" }

POST has a body that is JSON (in this case)

GET can get data from the querystring so thats where you need stringify
