如何防止用户输入错误的时间格式(客户端)

标签: c# asp.net-mvc view data-annotations timespan

我的模型包含两个保存时间的属性。我想让用户在视图中输入时间并防止其输入错误的值(例如07:66) 如果您知道JQuery中的一种方法可以屏蔽它。

public class WeeklyVW
{
   [StringLength(5)]
 //or time span
    public string Ws_startTime { get; set; }
   [StringLength(5)]
    public string Ws_EndTime { get; set; }
}

可见

@Html.TextBoxFor(m => m.Starthour, new { data_mask = "00:00", @class = "form-control" })

您可以通过用[DataType(DataType.Time)]装饰模型属性,然后根据需要格式化时间输入字段来实现功能。您需要做的第二件事是使用EditorFor标记而不是TextBoxFor来使它起作用。您的代码如下:

型号:

public class WeeklyVW
{
  [StringLength(5)]
  //or time span
  public string Ws_startTime { get; set; }
  [StringLength(5)]
  public string Ws_EndTime { get; set; }

  [Required]
  [DataType(DataType.Time)]
  [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:HH}")]
  public string Starthour {get;set;}
}

控制器:

public ActionResult Index()
{
    return View(new WeeklyVW());
}

查看:

@model HelloWorldMvcApp.WeeklyVW
@{
    Layout = null;
}

    @Html.EditorFor(m => m.Starthour, new { data_mask = "00:00", @class = "form-control" })
    @Html.ValidationMessageFor(m => m.Starthour)    
            </div>

可以在以下位置找到该应用程序的工作示例:https://dotnetfiddle.net/6GpRBu

  @Html.TextBoxFor(m => m.EndHour, new { @class = "form-control ", @type = "time" })

如果长度等于5,则文本框将无法获取更多值 型号

  [StringLength(5)]
  public string EndHour{ get; set;}
