[英]Date Validations - StartDate, EndDate MVC
I need to do validation on StartDate and EndDate 我需要在StartDate和EndDate上进行验证
Validations: 验证:
So far my code: 到目前为止我的代码:
object: 宾语:
[DisplayName("Effective Start Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
public DateTime EffectiveStartDate { get; set; }
[DisplayName("Effective End Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
public DateTime EffectiveEndDate { get; set; }
View: 视图:
</tr>
<tr>
<td class="lables"><%= Html.LabelFor(model => model.EffectiveEndDate)%></td>
<td class="data" id = "endDate"><%= Html.EditorFor(model => model.EffectiveEndDate)%>
<%= Html.ValidationMessageFor(model => model.EffectiveEndDate)%></td>
</tr>
<tr>
<td class="lables"><%= Html.LabelFor(model => model.ErrorCheckEnabled)%></td>
<td class="data" ><%= Html.TextAreaFor(model => model.ErrorCheckEnabled)%>
<%= Html.ValidationMessageFor(model => model.EffectiveEndDate)%></td>
</tr>
How should I go with validation. 我该如何进行验证。 Should I do on client site on
我应该在客户端网站上做什么
$("#frm").validate
[or] [要么]

This must be said: You should always do a server-side validation, as the user can turn off javascript and thus your validation won't be applied. 必须这样说:您应该始终进行服务器端验证,因为用户可以关闭javascript,因此不会应用您的验证。 But I recommend making client-side validation as well so the UX will be nicer.
但我建议进行客户端验证,以便UX更好。 Server-side and client-side validation can easily exist simultaneously.
服务器端和客户端验证可以轻松同时存在。
For server-side you can easily create your own validation attribute by deriving from the ValidationAttribute class. 对于服务器端,您可以通过从ValidationAttribute类派生来轻松创建自己的验证属性。 Look at this example:
看看这个例子:
[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)]
public class EndDateAttribute : ValidationAttribute
{
public EndDateAttribute(DateTime endDate)
{
EndDate = endDate;
}
public DateTime EndDate { get; set; }
public override bool IsValid(object value)
{
if (value == null)
return false;
DateTime val;
try
{
val = (DateTime)value;
}
catch (InvalidCastException)
{
return false;
}
if (val >= EndDate)
return false;
return true;
}
}
You can probably figure out how to make StartDate. 您可以弄清楚如何制作StartDate。
UPDATE: Using this is quite simple. 更新:使用它非常简单。 You just have to apply it to your properties as any other (validation) attribute.
您只需将其作为任何其他(验证)属性应用于您的属性。 For example
例如
[DisplayName("Effective Start Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
[StartDate(DateTime.Now)]
public DateTime EffectiveStartDate { get; set; }
[DisplayName("Effective End Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
[EndDate(new DateTime(2011, 9, 24)]
public DateTime EffectiveEndDate { get; set; }
