In this article I will explain with an example, how to save Form data to Database using jQuery AJAX in ASP.Net MVC Razor.
When the Add Button is clicked, the InsertCustomer Action method is called using jQuery AJAX and the details of Customer are sent as JSON object.
Finally, after insertion the ID of the inserted Customer record is returned back to the View in ASP.Net MVC Razor.

Controller
The Controller consists of the following Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
 
Action method for Inserting data to Database
Inside this Action method, the received Customer object is inserted into the Customers table and the updated Customer object with generated Customer Id is returned back to the calling jQuery AJAX function.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult InsertCustomer(Customer _customer)
    {
        using (CustomersEntities entities = new CustomersEntities())
        {
            entities.Customers.Add(_customer);
            entities.SaveChanges();
        }
 
        return Json(_customer);
    }
}
 
 
View
The View consists of two TextBoxes and a Button. The Button has been assigned with a jQuery Click event handler.
When the Add button is clicked, the Name and the Country values are fetched from their respective TextBoxes and then passed to the InsertCustomer Action method using jQuery AJAX function.
The ID of the Inserted record is displayed using JavaScript Alert Message Box.
@{
    Layout = null;
}
