如何防止生成验证属性？

I have a DateTime property in my model, but I'm only interested in the time part:

我的模型中有一个DateTime属性，但我只对时间部分感兴趣：

public class MyModel
{
    [Required, DataType.Time]
    public DateTime Time
}

In my view, I output it like so:

在我看来，我这样输出：

@Html.EditorFor(model => model.Time)

This used to generate the following html in MVC 3:

这用于在MVC 3中生成以下html：

<input class="text-box single-line" data-val="true" 
    data-val-required="The Time field is required." 
    id="Time" name="Time" type="time" value="" />

Now I'm trying this with MVC 4, and this is the html generated:

现在我正在尝试使用MVC 4，这是生成的html：

<input class="text-box single-line" data-val="true" 
    data-val-date="The field Time must be a date." 
    data-val-required="The Time field is required." 
    id="Time" name="Time" type="time" value="" />

There is an extra attribute data-val-date added, which results in a client side validation error, because a time (e.g. "10:30") isn't formated as a date.

添加了额外的属性data-val-date，这导致客户端验证错误，因为时间（例如“10:30”）未形成为日期。

I suppose this is a bug in MVC 4 (I reported it)? But until it's resolved, is there any way to prevent this attribute from being generated? Or even better, is there a way to let it be generated as a data-val-time in stead, so I can provide my own client side validation method for time fields?

我想这是MVC 4中的一个错误（我报告过）？但是在它解决之前，有没有办法阻止生成这个属性？或者更好的是，有没有办法让它作为数据值时间生成，所以我可以为时间字段提供自己的客户端验证方法？

Not ideal but it will do the job; use JavaScript in your master template to remove the validation:

不理想，但它会完成这项工作;在主模板中使用JavaScript来删除验证：

$(document).ready(function(){
    $("input[data-val-date]").removeAttr("data-val-date");
});

#2

Use [DataType("Time")] instead of [DataType(DataType.DateTime)]. This will make MVC not treat your variable as DateTime, and then it will not generate the "data-val-date" attribute.

使用[DataType（“Time”）]代替[DataType（DataType.DateTime）]。这将使MVC不将您的变量视为DateTime，然后它将不会生成“data-val-date”属性。

Essentially [DataType("Time")] makes your variable a custom type. However, you cannot use any other string name for the custom type. MVC tries to detect the underlying type for a custom type. Only when you name your custom type as "Time", it will give up the detection.

基本上[DataType（“Time”）]使您的变量成为自定义类型。但是，您不能使用任何其他字符串名称作为自定义类型。 MVC尝试检测自定义类型的基础类型。只有当您将自定义类型命名为“时间”时，它才会放弃检测。

I can say better option will be to write your own client side validation function. Otherwise you can do some spoofing which I wont say it is right way but it can solve your issue. I had similar issue with respect to MVC validation where I wanted to change the behavior of client side validation. Please see the link

我可以说更好的选择是编写自己的客户端验证功能。否则你可以做一些欺骗，我不会说这是正确的方式，但它可以解决你的问题。我有关于MVC验证的类似问题，我想改变客户端验证的行为。请看链接

The idea here is you manually add attributes such as "data-val-required" and "data-val" to your input field and then add validation message for it.

这里的想法是您手动将诸如“data-val-required”和“data-val”之类的属性添加到输入字段，然后为其添加验证消息。

Hope it helps you in some way.

编辑：

try this

尝试这个

Remove required field attr from model

从模型中删除必填字段attr

public class MyModel
{    
    public DateTime Time
}

Then add attributes to your control as shown below

然后向控件添加属性，如下所示

    @Html.TextBoxFor(model => model.Time, new Dictionary<string, object> { { "data-val-required", "required" }, { "data-val", "true" }})
    @Html.ValidationMessage("Time", "The Time field is required.")

I have tried setting the value of the input field as a javascript date object, which in turn passed the validation of the unobtrusive validation.

我已经尝试将输入字段的值设置为javascript日期对象，而后者又通过了不显眼的验证的验证。

$("#date-input-field").val(new Date(1,0,1970));
$.validator.unobtrusive.parse('#form');
var form = $('#form');
form.validate();

This is done with jQuery 1.7.2, validation.unobtrusive and mvc4.

这是通过jQuery 1.7.2，validation.unobtrusive和mvc4完成的。

Hope this helps.

希望这可以帮助。

The best way is to set ClientValidationEnabled and UnobtrusiveJavaScriptEnabled to false in the HtmlHelper class.

最好的方法是在HtmlHelper类中将ClientValidationEnabled和UnobtrusiveJavaScriptEnabled设置为false。

HtmlHelper.ClientValidationEnabled = false;
HtmlHelper.UnobtrusiveJavaScriptEnabled = false;
