ASP.NET MVC5 textarea not outlined in red on validation error
提问by Avrohom Yisroel
I am using ASP.NET MVC5 with Bootstrap, and have the following in a Razor view for a contact form...
我正在将 ASP.NET MVC5 与 Bootstrap 一起使用，并在 Razor 视图中为联系表单提供以下内容...
@using (Html.BeginForm("Contact", "Home", FormMethod.Post, new {role = "form"})) {
<div class="form-group">
@Html.LabelFor(model => model.theirname)
@Html.TextBoxFor(model => model.theirname, new {@class = "form-control", placeholder = "Enter your name"})
<div>@Html.ValidationMessageFor(model => model.theirname, "You must enter your name")</div>
@Html.LabelFor(model => model.theiremail)
@Html.TextBoxFor(model => model.theiremail, new {@class = "form-control", placeholder = "Enter your email"})
<div>@Html.ValidationMessageFor(model => model.theiremail, "You must enter your email address")</div>
@Html.LabelFor(model => model.message)
@Html.TextAreaFor(model => model.message, new {@class = "form-control", placeholder = "Enter message", cols = 40, rows = 5})
<div>@Html.ValidationMessageFor(model => model.message, "You must enter a message")</div>
<input type="checkbox" id="copytome" name="copytome" checked="@Model.copytome" /> <label for="copytome">Send me a copy of the message</label>
<div><input type="submit" value="Send" class="btn btn-default" /></div>
</div>
}
If the user clicks the submit button without filling in their name or email address, the validation message is displayed correctly, and the textboxes are outlined in red.
如果用户在没有填写姓名或电子邮件地址的情况下单击提交按钮，则会正确显示验证消息，并且文本框以红色轮廓显示。
However, the textarea doesn't get outlined, although the validation message is shown...
但是，尽管显示了验证消息，但文本区域没有被勾勒出来......
Here is the generated HTML...
这是生成的 HTML...
<form action="/Home/Contact" method="post" role="form">
<div class="form-group">
<label for="theirname">Your name</label>
<input class="input-validation-error form-control" data-val="true" data-val-required="The Your name field is required." id="theirname" name="theirname" placeholder="Enter your name" type="text" value="" />
<div><span class="field-validation-error" data-valmsg-for="theirname" data-valmsg-replace="false">You must enter your name</span></div>
<label for="theiremail">Your email</label>
<input class="input-validation-error form-control" data-val="true" data-val-required="The Your email field is required." id="theiremail" name="theiremail" placeholder="Enter your email" type="text" value="" />
<div><span class="field-validation-error" data-valmsg-for="theiremail" data-valmsg-replace="false">You must enter your email address</span></div>
<label for="message">Message</label>
<textarea class="input-validation-error form-control" cols="40" data-val="true" data-val-required="The Message field is required." id="message" name="message" placeholder="Enter message" rows="5">
</textarea>
<div><span class="field-validation-error" data-valmsg-for="message" data-valmsg-replace="false">You must enter a message</span></div>
<input type="checkbox" id="copytome" name="copytome" /> <label for="copytome">Send me a copy of the message</label>
<div><input type="submit" value="Send" class="btn btn-default" /></div>
</div>
</form>
Anyone any idea why the textarea isn't outlined in red?
任何人都知道为什么 textarea 没有用红色勾勒出来？

Presumably bootstrap doesn't include a style rule for invalid textarea elements. You could fix it by adding the following to your stylesheet:
大概 bootstrap 不包含无效 textarea 元素的样式规则。您可以通过在样式表中添加以下内容来修复它：
textarea.input-validation-error {
border-color: red;
}
