推荐答案

为此，我认为您有两种解决方法.首先，您只需将ajax发布到您的控制器(例如:

For this I think you have two ways of working around. First you can simply make a ajax post to your controller (say:

public JsonResult IsModelStateValid(YourModel model)
{
  return Json(ModelState.IsValid);
}

，基于此您可以做任何您想做的事情.其次，如果您不想拨打服务器电话，只需检查

and based on this you can do whatever you want. Second, if you don't want to make a server call, you can simply check

var isValid = $('#frm').valid()

在您的jquery提交事件或按钮单击事件中.如果启用了非侵入式验证，并且对ASP.NET MVC的所有内置验证有效，而对自定义验证无效，那么这将起作用.

in your jquery submit event or button click event. This will work if you have enabled unobtrusive validation and works for all in built validations of ASP.NET MVC, but not for your custom validation.
