Question

I’m trying the following:

$("#button_feedback").click(function () {
    $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: $('#button_feedback').data('url'),
        data: "{message: " + $('#feedback_content_wrapper textarea').val() + " }",
        dataType: "json",
        success: function (data) {
            alert(data);
        }
    });
});

<input type="button" value="Enviar" class="button" id="button_feedback" data-url="@Url.Action("SendMail", "Contacto")"/>

And in my controller:

public class ContactoController : Controller
    {
        ...

        public ActionResult Send_Mail(string message)
        {
            return Json(new { mensaje = "Correo enviado con éxito" });
        }
}

However I keep getting:

POST http://localhost:11280/Contacto/SendMail404 Not Found

Why? Everything seems correct!!!…

Answer 1

Your method name has an underscore. Either change your method name or modify the action in the UrlHelper to match with the underscore.

public ActionResult SendMail(string message) // note change from Send_Mail
{
    return Json(new { mensaje = "Correo enviado con éxito" });
}
