远程属性验证不在Asp.Net MVC中触发

Bha*_*han 5 c# jquery asp.net-mvc-3 remote-validation

这是我的型号代码

public class BlobAppModel
{
   [Required(ErrorMessage="Please enter the name of the image")]
   [Remote("IsNameAvailable","Home",ErrorMessage="Name Already Exists")]
   public string Name { set; get; }           
}

在我的控制器中我有

public JsonResult IsNameAvailable(string Name)
{
   bool xx= BlobManager.IsNameAvailable(Name);
   if (!xx)
   {
      return Json("The name already exists", JsonRequestBehavior.AllowGet);
   }
   return Json(true, JsonRequestBehavior.AllowGet);
}

在我的数据中我有

public static bool IsNameAvailable(string Name)
{
   var test = "";
   using (var x = new BlobTestAppDBEntities())
   {
       try
       {
            test=x.BlobApps.Where(m => m.Name == Name).FirstOrDefault().Uri;
            if (test != null)
               return false;
            else
               return true;
       }
       catch (Exception)
       {
          return true;
       }
   }
}

在我看来,我也添加了脚本

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
@using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
    {

    <td> @Html.Label("Name:") 
                 @Html.TextBoxFor(m => m.Name)
                 @Html.ValidationMessageFor(m=>m.Name)</td>}

但远程验证根本没有触发..我的代码有什么问题吗?

确保您的验证方法使用[AllowAnonymous]属性修饰(也可能需要[HttpPost]).

[AllowAnonymous]
public JsonResult IsNameAvailable(string Name)

还有一个提示:使用浏览器的开发人员工具(主流浏览器中的F12按钮)来查看Json请求的状态.

jquery.unobtrusive-ajax.js在视图中缺少该文件,请添加该文件,然后重试。

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>

如果没有的话,它是从小部件进入的
