客户端验证不适用于mvc 4

For some reason, i have this same code validating properly in mvc 3, but in mvc 4 client side validation is never being called. Essentially, i need the client-side validation to work inside the jquery modal dialog. Any thoughts as to why the client-side validation is not being called?

出于某种原因,我有相同的代码在mvc 3中正确验证,但在mvc 4中,客户端验证永远不会被调用。基本上,我需要客户端验证在jquery模式对话框中工作。有关为什么没有调用客户端验证的任何想法?

Web.config

<appSettings>
   <add key="webpages:Version" value="2.0.0.0" />
   <add key="webpages:Enabled" value="false" />
   <add key="PreserveLoginUrl" value="true" />
   <add key="ClientValidationEnabled" value="true" />
   <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

Controller:

 public ActionResult SaveExpense(Expense obj)
        {
            obj.ExpenseId = Guid.NewGuid();
            if (ModelState.IsValid)
            {
                context.expenses.Add(obj);
                context.SaveChanges();
                int total=context.expenses.Sum(x => x.cost);
                return Json(new {spent=total,status="Saved" });

            }
            else
                return Json(new { status="Error"});   
        }

Expense is my model having the fields of whose object is created as obj... Hope this will get you through now...

费用是我的模型,其对象的字段被创建为obj ...希望这会让你通过...
