MVC.net，在partiaview中具有表單，返回驗證並在發布到父視圖后

Question

我在局部視圖中創建了一個sendemail表單，用於不同視圖，例如（聯系人，題詞）

我的問題是我無法將錯誤消息或成功消息返回到父視圖

我嘗試不同的方式，我的兩個好時機是：

-）在控件中使用Partialviewresult（顯示消息，但在屏幕上僅是部分視圖，請進行重定向）

[HttpPost]
    public PartialViewResult _SendMail(MailModel obj)
    {

        if (ModelState.IsValid)
        {

            MailMessage mail = new MailMessage();
            mail.ReplyToList.Add(new MailAddress(obj.from));
            mail.To.Add(obj.to);
            mail.From = new MailAddress(obj.from);
            mail.Subject = obj.Subject;
            string Body = obj.Body;
            mail.Body = Body;
            mail.IsBodyHtml = true;
            SendMailerController.sendMailer(mail);
            ViewBag.courriel = "- votre courriel à été envoyé";
            return PartialView();
        }
        else
        {
            ViewBag.courriel = "- votre courriel à été envoyé";
            return PartialView();
        }
    }

將父視圖的名稱發送到partialview以隱藏輸入，並在控件中使用帶有redirectToAaction ...的操作結果，顯示良好的View，但不顯示消息。

上級控制器

 public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }

父視圖CONTACT.cshtml

@{
    ViewBag.Title = "Contact";
}
<h2>@ViewBag.Title.</h2>

        <section id="emailForm">
            @Html.Partial("_SendMail", new ViewDataDictionary(ViewData) { { "adresse", "Contact" } })
        </section>

部分視圖_SendMail

@model IdentitySample.Models.MailModel


@{
    ViewBag.Title = "Evoyez-nous un Courriel";
}
<h2>@ViewBag.Title</h2>
<fieldset>

    @using (Html.BeginForm("_SendMail", "Home", FormMethod.Post, new
    {
        @class = "form-horizontal",
        role = "form",
        @id = "Formulaire"
    }))
    {
        @Html.ValidationSummary("", new { @class = "text-error" })
    <div class="text-success"> @ViewBag.courriel </div>
    <table class="col-md-4">
        <tr>
            <td>To:</td>
            <td>@Html.TextBoxFor(m => m.to)</td>
        </tr>
        <tr>
            <td>Suject:</td>
            <td>@Html.TextBoxFor(m => m.Subject)</td>
        </tr>
        <tr>
            <td>Message</td>
            <td>@Html.TextAreaFor(m => m.Body)</td>
        </tr>

        <tr>
            <td>
                <input type="hidden" name="adresse" value="@ViewData["adresse"]" />
                @Html.TextBoxFor(m => m.from)
            </td>
            <td><input type="submit" value="Send" class="btn btn-default" /></td>
        </tr>
    </table>
        <br/>

    }
</fieldset>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

控制者發送電子郵件

[HttpPost]
        public ActionResult _SendMail(MailModel obj)
        {

            if (ModelState.IsValid)
            {

                MailMessage mail = new MailMessage();
                mail.ReplyToList.Add(new MailAddress(obj.from));
                mail.To.Add(obj.to);
                mail.From = new MailAddress(obj.from);
                mail.Subject = obj.Subject;
                string Body = obj.Body;
                mail.Body = Body;
                mail.IsBodyHtml = true;
                SendMailerController.sendMailer(mail);
                ViewBag.courriel = "- votre courriel à été envoyé";
                return RedirectToAction(obj.adresse, "Home");
            }
            else
            {
                ViewBag.courriel = "- votre courriel à été envoyé";
                return RedirectToAction("Contact", "Home");
            }
        }

和emai模型

using System.ComponentModel.DataAnnotations;
using System.Net.Mail;
namespace IdentitySample.Models
{
    public class MailModel
    {
        public string from { get; set; }

        [Required]
        [EmailAddress]
        [Display(Name = "Courriel")]
        public string to { get; set; }

        [Required]
        [StringLength(150, ErrorMessage = "Sujet trop long, max. 150 charactéres")]
        [DataType(DataType.Text)]
        [Display(Name = "Sujet")]
        public string Subject { get; set; }

        [Required]
        [StringLength(3000, ErrorMessage = "le message est de max. 3000 charactéres")]
        [DataType(DataType.Text)]
        [Display(Name = "Sujet")]
        public string Body { get; set; }

        public string adresse { get; set; }

    }
}

PD：發送電子郵件服務正常，顯示錯誤或成功消息是我的問題

Answer 1

最終我用AjaxForm制作起來更加容易。

下載jQuery插件。

我在局部視圖和函數簽名中做了一些更改。

准備好PartialView

@model IdentitySample.Models.MailModel


@{
    ViewBag.Title = "Evoyez-nous un Courriel";
}
<h3>@ViewBag.Title</h3>

<form method="post" class="form-horizontal" role="form" id="sendMail">
    @Html.AntiForgeryToken()
    @Html.ValidationSummary("", new { @class = "text-danger", @id="validation" })
    <div class="text-success" id="success"> @ViewBag.courriel </div>
    <div class="input-group row">
        @Html.LabelFor(m => m.to, new { @class = "input-group-addon" })
        @Html.TextBoxFor(m => m.to, new { @class = "form-control", @placeholder = "votrenom@courriel.com" })
    </div>
    <div class="input-group row">
        <p class="input-group-addon">sujet &nbsp; &nbsp; &nbsp;</p>
        @Html.TextBoxFor(m => m.Subject, new { @class = "form-control" })
    </div>
    <div class="input-group row">
        @Html.LabelFor(m => m.Body, new { @class = "input-group-addon" })
        @Html.TextAreaFor(m => m.Body, new { @class = "form-control", @rows = "8" })
    </div>
    <input type="hidden" name="adresse" value="@ViewData["adresse"]" />
    <input type="submit" value="Envoyer" class="btn btn-success" />
</form>

    @Scripts.Render("~/bundles/jqueryval")
    @Scripts.Render("~/bundles/form")
    <script type="text/javascript">
        $(function () {
            $("#sendMail").ajaxForm({
                url: "/Home/_SendMail?obj",
                dataType: 'json',
                success: processJson
            });

            function processJson(data) { 
                // 'data' is the json object returned from the server 
                $("#validation").html("");
                $("#success").html(data);
            }
        });
    </script>

控制器功能

[HttpPost]
        [ValidateAntiForgeryToken]
        public JsonResult _SendMail(MailModel obj)
        {
            if (ModelState.IsValid)
            {
                MailMessage mail = new MailMessage();
                mail.ReplyToList.Add(new MailAddress(obj.to));
                mail.To.Add(ConfigurationManager.AppSettings["mailAccount"]);
                mail.From = new MailAddress(ConfigurationManager.AppSettings["mailAccount"]);
                mail.To.Add(new MailAddress(obj.to));
                mail.Subject = "site web - " + obj.Subject;
                string Body = "Courriel de " + obj.to + " Contenu:  " + obj.Body;
                mail.Body = Body;
                mail.IsBodyHtml = true;
                if (!SendMailerController.sendMailer(mail)) return Json("error", JsonRequestBehavior.AllowGet);
                ViewBag.courriel = "- votre courriel à été envoyé";
                return Json("success", JsonRequestBehavior.AllowGet);  
            }
            return Json("error", JsonRequestBehavior.AllowGet); 

        }
