禁用 ASP.NET MVC 中某些字段的客户端验证

如何有条件地禁用某些字段的客户端验证？

这是我需要做的示例：

用户写下姓名和地址并提交。
两者都经过服务器端和客户端验证。如果验证通过，电子邮件将发送到给定地址，并存储（姓名，地址）对。
作为响应，这次会显示相同的页面（我不想重定向！）并进行确认。用户可以重新输入姓名并提交。在这种情况下，电子邮件将被重新发送到与给定名称相对应的地址。

它不起作用，因为：当用户单击第二个（确认屏幕）上的重新发送按钮时，客户端验证将不会通过。即使没有字段，它也会说电子邮件是必需的。如何在确认页面发送给用户之前禁用 javascript 验证电子邮件？

示例 ASP.NET MVC 页面

<%if (Model.Confirm == false){ %>
    <% using (Html.BeginForm()) { %>
        Your email: <%: Html.EditorFor(m => m.Email) %>
        Your name: <%: Html.EditorFor(m => m.Name) %>
        <input type="submit" value="Send Email" />
    <% } %>
<%} else{ %>
    The e-mail was send! You can write your name and click button to resend it.
    <% using (Html.BeginForm()) { %>
        Your name: <%: Html.EditorFor(m => m.Name) %>
        <input type="submit" value="Resend me email again" />
    <% } %>
<% } %>

在模型中，Email 和 Name 都是强制客户端验证的必填字段。

控制器操作示例

 public ActionResult Index(){
     return new MyModel {Confirm = false;}
 }

 [HttpPost]
 public ActionResult Index(MyModel model){
     if(DataHelper.isKnown(model.Name)){
         //send e-mail to the address corresponding to name in database 
     }
     if(!ModelState.IsValid) {
         return View(model);
     }
     //Send e-mail to address in email
     //store pair name->email to database
     model.Confirm = true;
     return View(model);
 }

How can I conditionally disable client-side validation of some fields ?

Here is the example of what I need to do:

user writes name and address and submits.
Both are validated both server and client side. If validation passes e-mail is send to given address and (name, address) pair is stored.
as a response same page is displayed (I don't want redirect!) this time with confirmation. User can retype their name and submit. In such case e-mail will be resend to the address that corresponds to given name.

It does not work because: client side validation will not pass when user clicks resent button on the second (confirmation screen). It would say that e-mail is required even if there is no field for it. How can I disable javascript validating email before the confirm page gets send to user ?

Example ASP.NET MVC page

<%if (Model.Confirm == false){ %>
    <% using (Html.BeginForm()) { %>
        Your email: <%: Html.EditorFor(m => m.Email) %>
        Your name: <%: Html.EditorFor(m => m.Name) %>
        <input type="submit" value="Send Email" />
    <% } %>
<%} else{ %>
    The e-mail was send! You can write your name and click button to resend it.
    <% using (Html.BeginForm()) { %>
        Your name: <%: Html.EditorFor(m => m.Name) %>
        <input type="submit" value="Resend me email again" />
    <% } %>
<% } %>

In the model both Email and Name are required field to enforce client side validation.

Example controller actions

 public ActionResult Index(){
     return new MyModel {Confirm = false;}
 }

 [HttpPost]
 public ActionResult Index(MyModel model){
     if(DataHelper.isKnown(model.Name)){
         //send e-mail to the address corresponding to name in database 
     }
     if(!ModelState.IsValid) {
         return View(model);
     }
     //Send e-mail to address in email
     //store pair name->email to database
     model.Confirm = true;
     return View(model);
 }

这只是一个简单的解决方案，我将隐藏第二次确认的电子邮件字段并保留其值。

<%} else{ %>
    The e-mail was send! You can write your name and click button to resend it.
    <% using (Html.BeginForm()) { %>
        <%: Html.HiddenFor(m => m.Email) %>
        Your name: <%: Html.EditorFor(m => m.Name) %>
        <input type="submit" value="Resend me email again" />
    <% } %>
<% } %>

Just a simple solution for this, I will hide the email field for the second confirmation and preserve its value.

<%} else{ %>
    The e-mail was send! You can write your name and click button to resend it.
    <% using (Html.BeginForm()) { %>
        <%: Html.HiddenFor(m => m.Email) %>
        Your name: <%: Html.EditorFor(m => m.Name) %>
        <input type="submit" value="Resend me email again" />
    <% } %>
<% } %>

为什么不使用 2 个不同的视图？您不必重定向。我认为你在这里违反了SRP。这一观点有不止一个目的。

public ActionResult SubmitEmail(Model model)
{
     if(!emailWasSent)
        return View("FirstView");
     else
        return View("ConfirmationView");
}

这样，第一个视图可以进行客户端验证，而第二个视图则不能选择它并按照自己的意愿行事。

Why don't you use 2 different views? You don't have to redirect. I think you are violating the SRP here. That view is serving more than one purpose.

public ActionResult SubmitEmail(Model model)
{
     if(!emailWasSent)
        return View("FirstView");
     else
        return View("ConfirmationView");
}

That way the first view can have client-side validation and the second view can not opt in for it and do as it wishes.
