范围和属性DisplayFormat时间跨度上 [英] Range and DisplayFormat Attributes on TimeSpan

问题描述

我建立一个调度屏需要显示时间字段，为用户输入一天日程安排的时间。

I am building a Scheduling Screen and need to display a Time field for users to enter the time of day for the schedule.

我不知道，如果这是最好的选择，但我使用领域的时间跨度。为了验证输入，我想使用Range属性和DisplayFormat属性。

I'm not sure if this is the best option, but I am using a TimeSpan for the field. To validate the input, I want to use the Range attribute and the DisplayFormat attribute.

当我调试，并进入一个看似有效的值，该范围属性表示超出范围错误。任何人都可以看到我在做什么错了？是时间跨度为这种用法正确的类型？ 。任何帮助是极大的赞赏。

When I debug and enter a seeming valid value, the Range attribute indicates an out of range error. Can anyone see what I am doing wrong? Is TimeSpan the proper type for this usage? Any help is greatly appreciated.

模型类：

public class Schedule
{
    public Schedule()
    {
        this.ScheduleTime = new TimeSpan(0, 0, 0);
    }

    /// <summary>
    /// The time of day for the schedule to run
    /// </summary>
    [Required, DataType(System.ComponentModel.DataAnnotations.DataType.Time),
    Display(Name = "Schedule Time", Description = "Number of Hours and Minutes after Midnight Central Timezone"),
    DisplayFormat(DataFormatString = @"{0:hh\:mm\:ss}", ApplyFormatInEditMode = true),
    Range(typeof(TimeSpan), "00:00", "23:59")]
    public TimeSpan ScheduleTime { get; set; }
}

错误消息：

推荐答案

您知道这些时候，你问一个问题，不久后你以前正确的答案只是出现？这是那些对我的一个

You know those times where you ask a question and shortly after the answer just appears right before you? This is one of those for me.

我发现这个职位的SO：
的为什么ASP.Net MVC范围属性采取类型？

I found this SO post: why does ASP.Net MVC Range Attribute take a Type?

描述了问题，因为jQuery的暂时无法处理范围表达式所以客户端验证将无法正常工作，但服务器端验证会。

Which describes the issue as jQuery being unable to handle the Range expression so the Client Side Validation won't work, but the Server Side Validation will.

所以我删除与JavaScript本领域的客户端验证：

So I removed the client validation for this field with javascript:

<script>
    $(document).ready(function () {
        $("#ScheduleTime").rules('remove', 'range');
    });
</script>

和现在的验证检查时正常工作的 ModelState.IsValid 在控制器中。

And now the validation works properly when checking the ModelState.IsValid in the controller.
