1.Model实体
/// <summary> /// 课程编号 /// </summary> [MaxLength(50)] [Remote("IsUnique_Available", "Course")] [Required(ErrorMessageResourceName = "Course_CourseNum", ErrorMessageResourceType = typeof(ErrorMessage))] public string CourseNum { get; set; }
2.CourseController控制器IsUnique_Available验证方法
#region 验证课程编号不唯一 public JsonResult IsUnique_Available(string CourseNum) { Course model = o_Res.GetCourseAny(a => a.CourseNum == CourseNum); if (model == null) { return Json(true, JsonRequestBehavior.AllowGet); } else { string suggestedUID = String.Format(CultureInfo.InvariantCulture, "课程编号:{0} 已经存在!", CourseNum); return Json(suggestedUID, JsonRequestBehavior.AllowGet); } } #endregion
