我可以在这里应用一些javascript或jquery，这样在点击提交按钮后，它必须检查值是否有效，如果可以的话。

请提供验证姓氏字段的代码......这不应该是空的。

我尝试过这个功能，但是它没有工作......

    protected void ValidateContact(ens.ContactPerson contactToValidate)
    {
        if (contactToValidate.FirstName.Trim().Length == 0)
            ModelState.AddModelError("FirstName", "First name is required.");
        if (contactToValidate.LastName.Trim().Length == 0)
            ModelState.AddModelError("LastName", "Last name is required.");
        if (contactToValidate.MiddleName.Trim().Length == 0)
            ModelState.AddModelError("MiddleName", "Invalid phone number.");
        if (contactToValidate.DateOfBirth.ToString().Trim().Length == 0)
            ModelState.AddModelError("Email", "Invalid email address.");
    }

Answer 1

您将要使提交按钮成为常规按钮，然后单击调用验证字段的javascript函数。如果验证通过，您可以使用$（“＃myForm”）。submit（）提交表单。您可以执行var lastName = $（“＃LastName”）。val（）等操作来获取姓氏文本框中的值，然后测试lastName中的值。

Answer 2

可能您可以使用Sys.Mvc.FormContext.getValidationForForm强制验证整个表单。示例：http://weblogs.asp.net/imranbaloch/archive/2010/07/11/asp-net-mvc-client-side-validation-with-dynamic-contents.aspx

您需要一些JavaScript参考。请遵循此http://www.gregshackles.com/2010/02/validating-hidden-fields-in-asp-net-mvc-2/

之后，你可以在提交按钮上调用任何javascript方法，进行javascript验证，然后提交表单。

 <script type="text/javascript" language="javascript">
    function ValidateLastName(name) {

       //all validation here

        var form = document.forms[0];
        form.action = '/AddressType/Create';
        form.submit();
    }
</script>

OR可能是其中之一可能有帮助，
