我的模特为
[Required]
[EmailAddress]
[Remote("EmailValidation", "Account", ErrorMessage = "{0} already has an account, please enter a different email address.")]
[Display(Name = "Email")]
public string Email { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[System.ComponentModel.DataAnnotations.Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
以及注册表格:
<form id="registrationForm">
@Html.AntiForgeryToken()
@Html.ValidationSummary(true, String.Empty, new { @class = "text-danger text-center" })
@Html.HiddenFor(m => m.ForModal, new { @Value = true })
<div class="form-group text-center">
<div class="input-group margin-top-10 margin-bottom-5">
<span class="input-group-addon"><i class="fa fa-user"></i></span>
@Html.TextBoxFor(m => m.Email, new { @class = "form-control", placeholder = "Email", @readonly = "readonly" })
</div>
@Html.ValidationMessageFor(m => m.Email, null, new { @class = "text-danger" })
<div class="input-group margin-top-10 margin-bottom-5">
<span class="input-group-addon"><i class="fa fa-lock"></i></span>
@Html.PasswordFor(m => m.Password, new { @class = "form-control", placeholder = "Password" })
</div>
@Html.ValidationMessageFor(m => m.Password, null, new { @class = "text-danger" })
<div class="input-group margin-top-10 margin-bottom-5">
<span class="input-group-addon"><i class="fa fa-lock"></i></span>
@Html.PasswordFor(m => m.ConfirmPassword, new { @class = "form-control", placeholder = "Confirm Password" })
</div>
@Html.ValidationMessageFor(m => m.ConfirmPassword, null, new { @class = "text-danger" })
</div>
<div class="text-right">
<button type="submit" class="btn-u btn-u-orange btn-u-wide" title="Join">Join</button>
</div>
</form>
当我键入短密码 - 验证触发时,当我输入不同的confirmPassword作为密码 - 验证触发,但当我只键入数字123456
时,客户端没有任何事情发生,只是在服务器端,毕竟我收到错误。

为什么我可以在客户端获得验证DataType.Password?
当我在互联网上搜索这样的问题时,我得到的解决方案就像use Html.PasswordFor or Html.EditorFor instead of Html.TextBoxFor
。
答案 0 :(得分:12)
DataType
属性不用于框中的验证,它主要用于渲染。例如,如果您使用EditorFor
在内部呈现属性,则会使用DataType
属性来确定应呈现的输入类型,即<input type="password" ... />
。 PasswordFor
基本上做同样的事情,但不需要DataType
属性。
您的长度验证适用于客户端,因为StringLength
属性不是DataType
。如果您想强制执行特定的数据类型验证,我建议您先使用RegularExpressionAttribute,然后考虑实施自己的custom validator。
