我想在我的MVC项目(单声道/ .NET 4.5)中使用数据注释。我创建了我的模型并添加了所有适当的注释。我有我的看法和控制器适当连线。然而,验证似乎并没有发生。我尝试了一切,我可以找到无济于事。由于这是我第一次使用Razor和Data Annotations,所以我想象一下我错过了一些安装程序,但是在我的生活中找不到它。这里是我的代码:在剃刀MVC数据注释

public string FirstName { get; set; }

public string DisplayName { get; set; }

public class AccountController : Controller

public ActionResult Register()

ViewData ["IsComplete"] = false;
ViewData ["RequiredVouches"] = WebSettings.RequiredVouches;
return View();
}
[HttpPost]
public ActionResult Register(FormCollection formData)
{
if (ModelState.IsValid) {
//TODO: Put the data
ViewData ["IsComplete"] = true;

return View();

<div class="group column-1">
@Html.LabelFor(modelItem => @Model.FirstName)
@Html.EditorFor(modelItem => @Model.FirstName, new { htmlAttributes = new { @class="form-control" } })
@Html.ValidationMessageFor(modelItem => @Model.FirstName)
@Html.LabelFor(modelItem => @Model.DisplayName)

@Html.LabelFor(modelItem => @Model.LastName)
@Html.EditorFor(modelItem => @Model.LastName, new { htmlAttributes = new { @class="form-control" } })
@Html.ValidationMessageFor(modelItem => @Model.LastName)
@Html.LabelFor(modelItem => @Model.EmailAddress)
@Html.EditorFor(modelItem => @Model.EmailAddress, new { htmlAttributes = new { @class="form-control" } })
@Html.ValidationMessageFor(modelItem => @Model.EmailAddress)
</div>
<div class="button-options">
<button id="btnSubmit" type="submit" formmethod="post" class="btn btn-danger">Submit</button>
<a id="btnCancel" href="~/" class="btn">Cancel</a>

</fieldset>
}
}
}
另外,我公顷我已经将jquery验证脚本添加到了我的布局文件中,并且还启用了web.confg中的客户端验证。
布局页眉
<head>
<!--some other css and such-->
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobstrusive.min.js"></script>
</head>
的Web.config
<appSettings>
<!--some other stuff-->
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
基本上,当我点击提交,它认为该模型是完全有效的(ModelState.IsValid控制器返回true )和验证的东西(我希望在发回控制器之前发射)似乎决不会触发。即使使用完全空白的表单(尽管有“必需的”数据注释),我也不会收到验证消息。我错过了什么?
在服务器上,“ModelState”永远不会失效,因为您不使用模型。把你的POST方法改为'public ActionResult Register(RegisterViewModel model)'在客户端你还包含了'jquery- {version} .js'? –
你是否在使用你的脚本包? –
