Question

我怀疑在ASP.NET MVC 3中完成了一个项目，其中有一个联系表单。它完美的工作问题是，我想发一条消息“电子邮件发送成功！”完成你的提交。我不是在使用Json。什么是最合适的解决方案谢谢！

代码：

Contato.cshtml `

@model SSInstitucional.ViewModel.ContatoViewModel
 @using System.Web     

<link href="../../Content/themes/SCTecno.css" rel="stylesheet" type="text/css" />

@using (Html.BeginForm("EnviaEmail")) 
{
    @Html.ValidationSummary(true, "")

    <div id ="divContato" style="text-align:left;  margin-left:460px; margin-right:400px; font-family:Verdana;">

            <div id="txtNome" class="editor-label">
                @Html.LabelFor(model => model.Nome)
               <p>
                @Html.TextBoxFor(m => m.Nome, new { id = "Nome", size = 40, maxlength = "60" })
                @Html.ValidationMessageFor(model => model.Nome)
            </div>
            <div id="txtEmail" class="editor-field">
                @Html.LabelFor(model => model.Email)
                <p>
                @Html.TextBoxFor(m => m.Email, new { id = "Email", size = 40, maxlength = "200" })
                @Html.ValidationMessageFor(model => model.Email)
            </div>
            <div  id="txtAssunto"class="editor-label">
               @Html.LabelFor(model => model.Assunto)
                <p>
                @Html.TextBoxFor(m => m.Assunto, new { id = "assunto", size = 40, maxlength = "200" })
                @Html.ValidationMessageFor(model => model.Assunto)
            </div>
            <div id="txtMensagem" class="editor-field">
               @Html.LabelFor(model => model.Mensagem)
               <p>
                @Html.TextAreaFor(model => model.Mensagem, new { id = "mensagem", rows = "10", cols = "50", maxlength = "5000" })
                @Html.ValidationMessageFor(model => model.Mensagem)
            </div>

                <div id="Enviar" onClick="alert('E-mail enviado com sucesso!!')")>
             @SSHtml.SubmitStyledButton("Enviar")
                </div>





   </div>
}

如果可以使用js，则可以使用MVC Ajax表单。这里有一个例子http://www.hanselman.com/blog/ASPNETMVCPreview4UsingAjaxAndAjaxForm.aspx

您只需要替换

@using (Html.BeginForm("EnviaEmail")) 
{
   ....
}

与

@using(Ajax.BeginForm("EnviaEmail", new AjaxOptions
                                                      {
                                                              UpdateTargetId = "form_wrapper_id",
                                                              InsertionMode = InsertionMode.Replace
                                                      }))
{
    ...
}

从Action回来一些按摩。此消息将放入ID为“form_wrapper_id”的HTML标记中。如果你不能使用js，Darin Dimitrov的答案是最好的。

您的表单目前指向EnviaEmail控制器操作。 EnviaEmail控制器操作不执行任何操作。它只重新显示视图。它不会发送任何电子邮件。所以我猜你的原始代码实际上指的是Index POST动作：

@using (Html.BeginForm())
{
    ...    
}

从我在代码中看到的内容，此POST操作会发送一封电子邮件并重新显示相同的视图。因此，一旦发送电子邮件，您就可以在ViewBag中存储一些消息：

[HttpPost]
public ActionResult Index(ContatoViewModel contatoViewModel)
{
    string corpo = "Nome: " + contatoViewModel.Nome + "\n" +
                       "E-Mail: " + contatoViewModel.Email + "\n" +
                       "Assunto: " + contatoViewModel.Assunto + "\n\n" +
                       contatoViewModel.Mensagem;

    sendEmail(contatoViewModel.Nome, contatoViewModel.Email, contatoViewModel.Assunto, corpo);

    ViewBag.Message = "Email sent successfully";
    return View();
}

然后在您的视图中显示以下消息：

<div>@ViewBag.Message</div>

ASP MVC：发送电子邮件并返回消息（No Json）
