Question

尝试使用MVC客户端验证时，我得到“formElement为null”。有没有人对这个问题有什么想法？

Sys.Mvc.NumberValidator.create = function（rule）{return Function.createDelegate（new Sys.Mvc.NumberValidator（），new Sys.Mvc.NumberValidator（）。validate）;}

这是我的模特：


public class EmailViewModel
    {
        /// 
        /// The user's current email address
        /// 
        public string CurrentEmailAddress { get; set; }

        /// 
        /// User's new email address
        /// 
        [EmailAddress( IsRequired = true, ErrorMessage = "Please enter a valid email address." )]
        public string NewEmailAddress { get; set; }

        /// 
        /// User's confirmed new email address
        /// 
        [EmailAddress( IsRequired = true, ErrorMessage = "Please enter a valid email address. Your emails do not match." )]
        public string ConfirmNewEmailAddress { get; set; }

        public EmailViewModel()
        {
            CurrentEmailAddress = "Michael.l.paterson@gmail.com";
            NewEmailAddress = string.Empty;
            ConfirmNewEmailAddress = string.Empty;
        }
    }

以下是母版页中的脚本引用：

MicrosoftAjax.js
MicrosoftMvcAjax.js
MicrosoftMvcValidation.js

我不确定是否所有这些都会显示，但这里是视图代码：

<script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script>

<%= Html.ValidationSummary( true, "There was an error when processing your request" ) %>
<% Html.EnableClientValidation(); %>
<% Html.BeginForm(); %>
    <div class="SecureForm_Wrapper">
        <label class="Styled">
            <img alt="Reqired" src="../../Content/Images/Misc/required.png" />
            New E-Mail</label>
        <div class="TheField">
            <%= Html.TextBoxFor( m => m.NewEmailAddress, new { id = "NewEmailAddress", name = "NewEmailAddress", @class = "CommonTextBox" } ) %>
            <%= Html.ValidationMessageFor( m => m.NewEmailAddress ) %>
        </div>
    </div>
    <div class="SecureForm_Wrapper">
        <label class="Styled">
            <img alt="Reqired" src="../../Content/Images/Misc/required.png" />
            Confirm New E-Mail</label>
        <div class="TheField">
            <%= Html.TextBoxFor( m => m.ConfirmNewEmailAddress, new { id = "ConfirmNewEmailAddress", name = "ConfirmNewEmailAddress", @class = "CommonTextBox" } )%>
            <%= Html.ValidationMessageFor( m => m.ConfirmNewEmailAddress ) %>
        </div>
    </div>
    <div id="BottomButtonContainer">
        <a class="button" href="#" id="SubmitButton" style="font-weight: bold;"><span>Save</span></a>
        <a class="button" href="#" onclick="this.blur(); return false;"><span>Cancel</span>
        </a>
    </div>
    <% Html.EndForm(); %>

这是

有没有人对可能出现的问题有任何想法？

当我将视图模型更改为使用Required属性（并删除IsRequired属性）时，您的视图模型和视图似乎对我来说很好。我还必须在表单中添加一个提交按钮。也许问题在于您实施EmailAddress验证器？

您可能希望对问题的格式更加小心，因为它使解析起来有点困难。作为参考，这里是我正在使用的视图模型和清理视图。

查看型号：

public class EmailViewModel
{
    /// 
    /// The user's current email address
    /// 
    public string CurrentEmailAddress { get; set; }

    /// 
    /// User's new email address
    /// 
    [Required(ErrorMessage = "Please enter a valid email address.")]
    public string NewEmailAddress { get; set; }

    /// 
    /// User's confirmed new email address
    /// 
    [Required(ErrorMessage = "Please enter a valid email address. Your emails do not match.")]
    public string ConfirmNewEmailAddress { get; set; }

    public EmailViewModel()
    {
        CurrentEmailAddress = "Michael.l.paterson@gmail.com";
        NewEmailAddress = string.Empty;
        ConfirmNewEmailAddress = string.Empty;
    }
}

查看：

<%= Html.ValidationSummary( true, "There was an error when processing your request" ) %>
<% Html.EnableClientValidation(); %>

<% using (Html.BeginForm())
   { %> 

    New E-Mail 
    <%= Html.TextBoxFor(m => m.NewEmailAddress)%> 
    <%= Html.ValidationMessageFor(m => m.NewEmailAddress)%> 
    <br />

    Confirm New E-Mail 
    <%= Html.TextBoxFor(m => m.ConfirmNewEmailAddress)%> 
    <%= Html.ValidationMessageFor(m => m.ConfirmNewEmailAddress)%> 
    <br />

    <input type="submit" value="Submit" />

<% } %>

<script src="<%= ResolveUrl("~/Scripts/MicrosoftAjax.js") %>" type="text/javascript" language="javascript"></script>
<script src="<%= ResolveUrl("~/Scripts/MicrosoftMvcAjax.js") %>" type="text/javascript" language="javascript"></script>
<script src="<%= ResolveUrl("~/Scripts/MicrosoftMvcValidation.js") %>" type="text/javascript" language="javascript"></script>

使用Mvc客户端验证时，formElement为null
