Question

[DataType(DataType.EmailAddress, ErrorMessage = "A Valid Email Address is Required.")]
[Required(ErrorMessage = "Email Address is Required.")]
public string email { get; set; }

<div class="row">
    @Html.LabelFor(model => model.email, "Email:")
    @Html.TextAreaFor(model => model.email, new { @Style = "height:20px; width:300px; resize:none;", id = "emailV" })
    @Html.ValidationMessageFor(model => model.email)
</div>

我故意插入虚假的电子邮件，以便错误消息显示在页面上，但它永远不会出现，如果我将其留空，则所需的错误消息会按预期显示。如何才能将有效的电子邮件地址错误显示在页面上，而不是仅仅抛出异常？

Answer 1

按照polybios

的提法进行尝试

模型

[EmailAddress(ErrorMessage = "A Valid Email Address is Required.")]
[Required(ErrorMessage = "Email Address is Required.")]
public string email { get; set; }

Answer 2

尝试

[EmailAddress(ErrorMessage = "A Valid Email Address is Required.")]

而不是

[DataType(DataType.EmailAddress, ErrorMessage = "A Valid Email Address is Required.")]

Answer 3

在页面中添加以下javascript。

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

web.config文件中的

请添加/检查以下标记

 <appSettings>
<add key="ClientValidationEnabled" value="true"/>
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>

要么 mvc [DataType(DataType.EmailAddress) no validation 请尝试以上两件事，请告诉我

错误消息未按预期显示
