【问题描述】:
我正在开发一个 ASP .Net MVC 4 Web 应用程序。在这里,我尝试使用 jQuery 的验证和不显眼的插件来实现验证。示例代码如下所示
注册模式
public class Signup
{
[StringLength(256,ErrorMessage ="Name can have maximum of 256 characters.")]
[Required]
public string Name { get; set; }
[Required]
[StringLength(10, ErrorMessage = "User code should have of 10 character.", MinimumLength = 10)]
public string UserCode { get; set; }
[StringLength(256, ErrorMessage = "Password can have maximum of 256 characters.")]
[Required]
public string Password { get; set; }
[StringLength(256, ErrorMessage = "Confirm Password can have maximum of 256 characters.")]
[Required]
public string ConfirmPassword { get; set; }
}
Signup.cshtml
@using (Html.BeginForm("SubmitSignUp", "Foobbox", Model, FormMethod.Post)) {
@Html.ValidationSummary()
<span class="input-group-addon">
<i class="material-icons">face</i>
</span>
@Html.EditorFor(x => x.Name, new { @class="form-control", @placeholder = "Name"})
@Html.ValidationMessageFor(x => x.Name)
</div>
<div class="input-group">
<span class="input-group-addon ">
<i class="material-icons">email</i>
</span>
@Html.TextBoxFor(x => x.EmailId, new { @class = "form-control", @placeholder = "Email" })
@Html.ValidationMessageFor(x => x.EmailId)
</div>
}
<head>标签下
<script src="~/Scripts/jquery-1.10.2.min.js" type="text/javascript"></script>
<script src="~/Scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>
上面指定的验证是在 HTML 中生成数据验证属性
例如:
<input class="text-box single-line" data-val="true" data-val-length="Name can have maximum of 256 characters." data-val-length-max="256" data-val-required="The Name field is required." id="Name" name="Name" type="text" value="">
问题是我无法向用户显示相应的错误消息。有什么我想念的吗?还是我做错了什么?
【问题讨论】:
-
那么当你提交表单时会发生什么?
-
因为我正在检查模型在我的控制器中是否有效,所以它不接受请求。所以基本上什么都没有发生
-
你的意思是它不接受请求 ??您的表单提交了吗?
-
是的,正在提交表单。但正如我已经说过的,控制器只有在提交的模型有效时才会接受请求。
-
@Sasu 您是否在 web.config 中启用了客户端验证密钥
