ASP.Net MVC 3 中的远程验证：如何在操作方法中使用AdditionalFields

发布于 2024-10-12 23:09:13 字数 553 浏览 6 评论 0原文

我一直在使用新的 ASP.Net MVC 3 RemoteAttribute 将远程调用发送到具有单个参数的操作方法。现在我想使用AdditionalFields 属性传入第二个参数：

[Remote("IsEmailAvailable", "Users", AdditionalFields = "InitialEmail")]

其中IntialEmail 是视图中的隐藏字段。该操作如下所示：

public JsonResult IsEmailAvailable(
            string email,
            string InitialEmail)
{
//etc.
}

当呈现视图时，隐藏字段被填充，但是当远程触发 Action 方法时，该值是一个空字符串。

我在其他地方看到大小写敏感可能是一个问题，因此我确保 Action 方法的两个参数具有相同的大小写。

还有其他建议吗？这个AdditionalFields过去被称为Fields。

谢谢，

I've been using the new ASP.Net MVC 3 RemoteAttribute to send a remote call to an action method that had a single parameter. Now I want to pass in a second parameter using the AdditionalFields property:

[Remote("IsEmailAvailable", "Users", AdditionalFields = "InitialEmail")]

Where IntialEmail is a hidden field in the view. The action looks like so:

public JsonResult IsEmailAvailable(
            string email,
            string InitialEmail)
{
//etc.
}

When the view is rendered, the hidden field is populated, but when the Action method is triggered remotely, the value is an empty string.

I've seen elsewhere case sensitivity may be an issue, so I've ensured the Action method has the same case for both parameters.

Any other suggestions? This AdditionalFields used to be called Fields.

Thanks,

奇怪的。它对我有用：

模型：

public class MyViewModel
{
    [Required]
    [Remote("IsEmailAvailable", "Home", AdditionalFields = "InitialEmail")]
    public string Email { get; set; }
}

控制器：

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }

    public ActionResult IsEmailAvailable(string email, string initialEmail)
    {
        return Json(false, JsonRequestBehavior.AllowGet);
    }
}

视图：

@model AppName.Models.MyViewModel
@{
    ViewBag.Title = "Home Page";
}
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
@using (Html.BeginForm())
{
    @Html.TextBoxFor(x => x.Email)
    @Html.ValidationMessageFor(x => x.Email)
    <input type="hidden" name="InitialEmail" value="[email protected]" />
    <input type="submit" value="OK" />
}

IIRC ASP.NET MVC 3 RC2 中存在一些错误，此远程验证已在 RTM 中修复。

Strange. It works for me:

Model:

public class MyViewModel
{
    [Required]
    [Remote("IsEmailAvailable", "Home", AdditionalFields = "InitialEmail")]
    public string Email { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }

    public ActionResult IsEmailAvailable(string email, string initialEmail)
    {
        return Json(false, JsonRequestBehavior.AllowGet);
    }
}

View:

@model AppName.Models.MyViewModel
@{
    ViewBag.Title = "Home Page";
}
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
@using (Html.BeginForm())
{
    @Html.TextBoxFor(x => x.Email)
    @Html.ValidationMessageFor(x => x.Email)
    <input type="hidden" name="InitialEmail" value="[email protected]" />
    <input type="submit" value="OK" />
}

IIRC there was some bug in ASP.NET MVC 3 RC2 with this remote validation that was fixed in the RTM.
