Get value from Controller using JQuery AJAX

Question

I want to get new value from controller and set it to view when form submit.

Controller:

public JsonResult GetVoucherNo()
    {
        var voucherno = 1001;

        var lastvoucherno = db.PaymentsAndReceipts.Where(x => x.StakeHolder.StakeHolderType.Name == "Supplier").OrderBy(x => x.VoucherNo).ToList().LastOrDefault();

        if (lastvoucherno != null)
        {
            voucherno = lastvoucherno.VoucherNo.GetValueOrDefault() + 1;
        }

        return new JsonResult { Data = voucherno, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
    }

My Jquery function:

I just want to do when this function calls, I can get the value from controller action.

function getVoucherNo()
{
    $.ajax({
        contentType: 'application/json; charset=utf-8',
        url: 'Payments/GetVoucherNo',
        dataType: "json"
    }).done(function () {
    //don't know what to do here.
    });
}

you can do a .success() and .fail() before you do the done. Just for example do .done((result) => { console.log(result); }); — Jordec

The data should be available in the done function argument like this:

function getVoucherNo()
{
   $.ajax({
      contentType: 'application/json; charset=utf-8',
      url: 'Payments/GetVoucherNo',
      dataType: "json"
   }).done(function (result) {
     //don't know what to do here.
     console.log(result);
     //you should see the exact JSON you return from the controller
   });
}

I done it with success.

function getVoucherNo()
{
    $.ajax({
        contentType: 'application/json; charset=utf-8',
        url: '/Payments/GetVoucherNo',
        dataType: "json",
        success: function (result) {
            console.log(result);
            return $('#VoucherNo').val(result); //to set value in textbox.
        },
        error: function (xhr, status, error) {
            alert(xhr);
            console.log(xhr, status, error);
        }
    });
}
