asp.net MVC4客户端模型验证

我的模型验证不在客户端浏览器中显示错误消息。表单被提交，但在我的控制器中，我的ModelState.IsValid为false，并在我的ModelState对象中显示了相应的错误消息。我不知道如何调试出了什么问题。asp.net MVC4客户端模型验证

你的问题之外，似乎有点误导，但我想你会问，为什么客户端验证不工作。请确保您有您的网页上这两个脚本：

~/Scripts/jquery.unobtrusive.min.js 

~/Scripts/jquery.validate.min.js

我通常把它们放在一个包内BundleConfig.cs

bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
        "~/Scripts/jquery.unobtrusive*", 
        "~/Scripts/jquery.validate*"));

通过使用星号*而不是min.js所述捆绑将使用非缩小的版本正在开发中，并将在生产中使用缩小版。

然后在我的页面布局：

@Scripts.Render("~/bundles/jqueryval")

谢谢尼克，我错过了这个！ – user2721870

使用ModelState.IsValid()左右，赶上这将解释了什么毛病的ModelState

我使用我的控制器上，并为“假”与我的模特属性相应的错误信息。但我不明白为什么我的表单在验证失败时被提交。这些消息也没有显示在我的浏览器页面中。 – user2721870

他已经表示他知道他的模型为什么无效，他在问为什么验证不会发生客户端（JavaScript）。 –

我的不好，没有正确地阅读这个问题。请原谅我:( –
