我对Ajax表单提交有疑问。这是代码:
控制器
[HttpPost, ValidateAntiForgeryToken, ValidateInput(true)]
public ActionResult Contact(ContactForm model)
{
if (!ModelState.IsValid)
{
return new EmptyResult();
}
else
{
string message = model.Name + " " + model.Telephone + " " + model.Email + " " + model.Address + " " + model.City + " " + model.ZipCode;
//send it
return new EmptyResult();
}
}
查看
<script type="text/javascript">
function PostSuccess() {
$('.success-message').html("Thank you for your interested");
}
function PostFailure() {
$('.success-message').html("Something went wrong... Make sure the required fields are filled out and in correct format");
}
</script>
<div class="contact-form">
@using (@Ajax.BeginForm("Contact", "Info", new AjaxOptions { HttpMethod = "Post", OnFailure = "PostFailure", OnSuccess = "PostSuccess" }))
{
<p>
@Html.LabelFor(x => x.Name, "Your name")
@Html.TextBoxFor(x => x.Name, new { @class = "required" })<span class="required">*</span>
</p>
<p>
@Html.LabelFor(x => x.Email, "Your email")
@Html.TextBoxFor(x => x.Email)<span class="required">*</span>
</p>
<p>
@Html.LabelFor(x => x.Telephone, "Your phone")
@Html.TextBoxFor(x => x.Telephone)<span class="required">*</span>
</p>
<p>
@Html.LabelFor(x => x.Address, "Your address")
@Html.TextBoxFor(x => x.Address)
</p>
<p>
@Html.LabelFor(x => x.ZipCode, "Your zipcode")
@Html.TextBoxFor(x => x.ZipCode)
</p>
<p>
@Html.LabelFor(x => x.City, "Your city")
@Html.TextBoxFor(x => x.City)
</p>
@Html.AntiForgeryToken()
<button type="submit" id="bContact">Send Message</button>
}
<div class="required">* Required Fields</div>
<div class="success-message">Output</div>
我想要的只是“成功消息”课程中的相应消息,但POST总是成功的,所以我总是得到“感谢您的兴趣。”
谢谢。

如果我理解正确,您希望对您的表单进行验证。也就是说,如果用户输入了一些无效输入,您希望显示PostFailure
中的消息,并强制用户在运行控制器的else
语句中的代码之前进行更正。您尚未发布模型,因此我不知道您是否正在执行此操作,但要验证表单您应使用Data Annotations。
例如,您的模型应包含:
[Required(ErrorMessage = "Name is required!")]
public string Name { get; set; }
表示名称字段。您可以将消息更改为您想要的任何内容,如果您愿意,可以使用特定于Name
的消息而不是您拥有的消息。
然后在视图中,您应该包括:
@Html.ValidationMessageFor(x => x.Name)
一定要包括:
<appSettings>
<add key="ClientValidationEnabled" value="true"/>
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>
</appSettings>
在您的web.config
文件中启用客户端验证(假设您已包含jQuery验证库,但默认情况下它们包含在ASP.NET MVC3项目中)。

要在“success-message”类中获取相应的消息,您必须更改操作中的代码。 如:
[HttpPost, ValidateAntiForgeryToken, ValidateInput(true)]
public ActionResult Contact(ContactForm model)
{
if (!ModelState.IsValid)
{
return Json("", JsonRequestBehavior.AllowGet);
}
else
{
string message = model.Name + " " + model.Telephone + " " + model.Email + " " + model.Address + " " + model.City + " " + model.ZipCode;
return Json(message, JsonRequestBehavior.AllowGet);
}
}
并且在成功函数中,你将参数放在那里。
function PostSuccess(data) {
$('.success-message').html(data);
}

OnSuccess
和OnFailure
表示AJAX调用是成功还是失败。来自MSDN的OnFailure:
This function is called if the response status is not in the 200 range.
您可以执行以下操作以使OnFailure运行:
throw new HttpException(404, "Not Found");
但我建议最好更改成功事件以调用一个解析调用结果的javascript函数。
