1. ClientValidationEnabled

   在asp.net mvc 5中ClientValidationEnabled默认为TRUE，所以也不需要刻意去设置

2. 应用ValidationAttribute

   这里使用内置的RequiredAttribute来演示

   public class Book    {        [Required(ErrorMessage = "BookID Is Required")]        public string BookID { get; set; }             public string Title { get; set; }        public string Date { get; set; }    }

    

3. 引用相关JQuery

    

4. 在View中显示错误消息
   @Html.ValidationSummary()   @Html.ValidationMessageFor(o => o.BookID)

    

5. DOMReady中设置validate

 客户端view总览

    
                            
     
           @Html.ValidationSummary()        @Html.ValidationMessageFor(o => o.BookID)             BookID   @Html.EditorFor(o => o.BookID)              Title            @Html.EditorFor(o => o.Title,new { @value= "WCF解密" })        Day     
              Month   
              Year    
              
          
     

 在这个例子中当你提交表单的时候，会验证客户端的数据是否符合validationAttribute的设置，如果不满足条件则显示错误提示
