在ASP.NET MVC某些领域禁用客户端验证 [英] Disable client side validation for some fields in ASP.NET MVC

问题描述

我如何有条件地禁用一些领域的客户端验证？

下面是什么，我需要做的例子：

• 用户写的名字和地址并提交。


• 两者都验证服务器和客户端。如果验证通过电子邮件被发送给定的地址和（姓名，地址）对存储。


• 当显示的响应同一页面（我不想重定向！）这个时候确认。用户可以重新输入他们的名字，并提交。在这种情况下，电子邮件将被重新发送到对应于给定名称的地址。

它不起作用，因为：当用户点击重新发送第二（确认屏幕）按钮客户端验证将无法通过。它会说，即使是它没有字段的电子邮件是必需的。我怎样才能禁用javascript验证电子邮件确认页面之前被发送到用户？

为例ASP.NET MVC页

 ＆LT;若％（Model.Confirm == FALSE）{％GT;
    ＆下;使用％（Html.BeginForm（））{％GT;
        你的电子邮件：＆LT;％：Html.EditorFor（M = GT; m.Email）％GT;
        您的名字：＆LT;％：Html.EditorFor（M = GT; m.Name）％GT;
        ＆LT;输入类型=提交值=发送电子邮件/＆GT;
    ＆LT;％}％GT;
＆LT;％}其他{％GT;
    电子邮件是发送！你可以写你的名字，然后点击按钮来重新发送。
    ＆下;使用％（Html.BeginForm（））{％GT;
        您的名字：＆LT;％：Html.EditorFor（M = GT; m.Name）％GT;
        ＆LT;输入类型=提交值=重新发送电子邮件我再次/＆GT;
    ＆LT;％}％GT;
＆LT;％}％GT;
 

在模型中均为电子邮件和名称需要现场执行客户端验证。

例控制器动作

 公众的ActionResult指数（）{
     返回新为MyModel {确认= FALSE;}
 } [HttpPost]
 公众的ActionResult指数（为MyModel模型）{
     如果（DataHelper.isKnown（model.Name））{
         //发送电子邮件到相应的数据库来命名地址
     }
     如果（！ModelState.IsValid）{
         返回查看（模型）;
     }
     //发送电子邮件的电子邮件解决
     //商店对名字 - ＆GT;电子邮件数据库
     model.Confirm = TRUE;
     返回查看（模型）;
 }
 

解决方案

你为什么不使用2个不同的看法？你不必重定向。我认为你在这里违反了SRP。这种观点是服务多个目的。

 公众的ActionResult SubmitEmail（型号模型）
{
     如果（！emailWasSent）
        返回视图（的firstView）;
     其他
        返回视图（ConfirmationView）;
}
 

这样，第一种观点可以有客户端验证，第二视图不能选择为它做，因为它的愿望。

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);
 }

解决方案

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.
