显示RemoteAttribute的结果在MVC 3.0 [英] Display the Result of RemoteAttribute in MVC 3.0

问题描述

我有一个视图模型设置使用 RemoteAttribute 使用RemoteValidation。它工作正常。

I have a ViewModel setup to use RemoteValidation using the RemoteAttribute. It works fine.

更新有点表现出一些固定的code。

Updated it a bit to show some fixed code.

我要指出的是，这不是我的实际注册code。这是测试，所以我可以在其他场合使用它。我没有让用户使用平板的名字注册！

I want to point out that this is not my actual "Register" code. This is testing it so I can use it in other situations. I'm not having users register using flat names!

下面是我引用库以及如何我引用他们。

Here are the libraries I am referencing, and how I am referencing them.

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.js"></script>

<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.validate/1.7/jquery.validate.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.min.js"></script>

下面是怎么了布线RemoteAttribute。

Here is how I am wiring the RemoteAttribute.

public class UserRegistrationModel
{
    [Required]
    [RegularExpression(@"^(?:[a-zA-Z\p{L} \.'\-]{3,48})$", ErrorMessage = "This name contains invalid characters. Names must be between 3 and 48 characters, contain only standard unicode symbols, and may not contain any punctuation other than the ['] and [-] symbols.")]
    [Remote("ValidateUserName", "Membership", ErrorMessage = "{0} is invalid.")]
    public string Name
    {
        get;
        set;
    }
}

然后这里是实际控制人的行为。

And then here is the actual controller behavior.

    public ActionResult ValidateUserName(string name)
    {
        // perform logic

        if (true)
            return Json(true, JsonRequestBehavior.AllowGet);

        return Json(false, JsonRequestBehavior.AllowGet);
    }

我已经检查了我的HTML，而这个功能我想要的。但我不明白从那里做。我怎样才能显示信息给用户？它只是将其存储在HTML

I have inspected my HTML, and this functions as I want. But I don't understand what to do from there. How can I display that information to the user? It just stores it in the html

数据-VAL-远程=*是无效的

我都看过，而且我注意到，即使在 RemoteAttribute 返回false，从

I have watched, and I notice that even when the RemoteAttribute returns false, the html changes from

值到值类=有效，但在我的其他模型验证，这会更改`类=输入验证错误'。

value to value class="valid", but in my other model validations, this changes to `class="input-validation-error"'.

因此​​，没有人对如何绘制远程消息发回任何线索？或者是有真的没有什么我能做什么？

So does anyone have any clues on how to draw the remote message back? Or is there really nothing I can do?

推荐答案

以下工作正常，我：

public class UserRegistrationViewModel
{
    [Required]
    [RegularExpression(@"^(?:[a-zA-Z\p{L} \.'\-]{3,48})$", ErrorMessage = "This name contains invalid characters. Names must be between 3 and 48 characters, contain only standard unicode symbols, and may not contain any punctuation other than the ['] and [-] symbols.")]
    [Remote("ValidateUniqueName", "Home")]
    public string Name { get; set; }
}

控制器：

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

    public ActionResult ValidateUniqueName(string Name)
    {
        if (NameIsValid(Name)) 
        {
            return Json(true, JsonRequestBehavior.AllowGet);
        }

        return Json(string.Format("{0} is invalid", Name), JsonRequestBehavior.AllowGet);
    }
}

查看：

@model AppName.Models.UserRegistrationViewModel

<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.Name)
    @Html.ValidationMessageFor(x => x.Name)
    <input type="submit" value="OK" />
}
