Try with below steps:

Step 1: Code for Action

C#

[HttpPost]
public ActionResult FillAdvanceDetails(string empId)
{
	var advanceDetials = (from f in db.PettyCashes where f.PettyCashTypeID.ToString() == empId select f).ToList();
	return Json(advanceDetials);

}

Step 2: Code for Javascript

JavaScript

<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>

<script>
    var jsonObj = { "empId": $("#DDL_Employee option:selected").val())  };

    $.ajax({
        url: '@Url.Action("FillAdvanceDetails", "AdvancePaymentDetails")',
        type: "POST",
        data: JSON.stringify(jsonObj),
        contentType: "application/json",
        datatype: "json",
        success: function (data) {
            if (data != null) {
                var vdata = data;
                $('#fuelTotalAmount').val(vdata.empId);
            }
        }
    });
</script>
