自定义属性的客户端验证

Question

为什么我的客户端验证不起作用。

属性是：

  [Required(ErrorMessage = "Email address is required")]
  [EmailAddress(ErrorMessage = "Invalid Email Address")]
  [NonCompanyEmailAttribute(ErrorMessage = "Email address of customer required (not company employees)")]
        public string EmailAddress

验证属性是：

public class NonCompanyEmailAttribute : ValidationAttribute, IClientValidatable
{
    public override bool IsValid(object value)
    {
        bool containscompany = !((string)value).ToLower().Contains("@company.com");
        return containscompany;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        yield return new ModelClientValidationRule
        {
            ErrorMessage = this.ErrorMessage,
            ValidationType = "noncompanyemail"
        };
    }
}

在 JS 中我有：

  $.validator.addMethod("noncompanyemail", function (value, element, params) {
            return value.toLowerCase().indexOf('company.com' > -1);
        });


        $.validator.unobtrusive.adapters.add("noncompanyemail", function (options) {
            options.rules["noncompanyemail"] = true;
            options.messages["noncompanyemail"] = options.message;
        });

包括

jquery.validate.js 和 jquery.validate.unobtrusive.js

我不确定您所说的 "not working" 是什么意思，但是您的 jquery 验证函数的格式似乎很奇怪。如果该值在任何地方包含 company.com，我假设您希望它为 return false（也称为无效）。如果是这样，您的方法应该类似于：

$.validator.addMethod("noncompanyemail", function (value, element, params) {
            return (value.toLowerCase().indexOf('company.com') == -1);
        });
