MVC4数据注解和验证
model中的验证注解特性:
public class StuInfo
{
public int ID { get; set;}
[Display(Name = "姓名")] //设置要显示的字段名
[Required(ErrorMessage = "您需要填写{0}")] //设置为必须字段 已经错误提示
[StringLength(50, MinimumLength = 3)] //设置最大长度和最小长度
public string Name { get; set;}
[Display(Name = "年龄")]
[Range(1, 150, ErrorMessage = "年龄填写不正确!")] //设置 值范围
public int Age { get; set;}
[Display(Name = "身高")]
[Range(typeof(decimal),"50.00", "250.00",ErrorMessage = "身高超出指定范围")]
public decimal Height { get; set;}
[Display(Name = "生日")]
[DataType(DataType.Date,ErrorMessage = "{0}格式不正确")] //设置数据类型以及错误提示
public DateTime Birthday { get; set;}
[Display(Name = "电话")]
[Remote("CheckPhone","StuInfo", ErrorMessage = "{0}已被注册")] //在指定的Conteroller中的通道(route)中验证数据
public string Phone { get; set;}
[Display(Name = "地址")]
[DataType(DataType.MultilineText)]
public string Address { get; set;}
[Display(Name = "电子邮箱")]
[RegularExpression(@"(\w)+(\.\w+)*@(\w)+((\.\w+)+)",ErrorMessage = "{0}格式不正确")] //正则验证
public string Email { get; set;}
[Display(Name = "再次输入电子邮箱")]
[Compare("Email",ErrorMessage = "{0}两次输入不一致")] //设置比较两个字段的值
public string EmailConfirm { get; set;}
[Display(Name = "密码")]
[DataType(DataType.Password)]
public string Password { get; set;}
[Display(Name = "备用电子邮箱")]
[DataType(DataType.EmailAddress,ErrorMessage = "{0}格式不正确")]
public string email_B { get; set;}
}
远程验证的通道:
public JsonResult CheckPhone(string phone)
{
var result= StuInfoBll.FindPhone(phone).count == 0;
return Json(result, JsonRequestBehavior.AllowGet);
}
效果:
正常下的网页:
必须字段验证效果:
值范围、值类型验证效果:
正则验证和比较字段值效果:
数据类型验证效果:
