是否可以使用 MVC 非侵入式适配器在验证功能期间自定义 jquery 验证消息？
我有一个 MVC3 表单中的多个select 列表框。用户可以添加&从该列表框中删除自定义 option 元素。但是我想验证列表框中没有两个选项包含相同的值。
我创建了一个实现 IClientValidatable 的自定义 ValidationAttribute。服务器和客户端验证都正常工作。但是，我的 ErrorMessage 看起来像这样：
ErrorMessage = "{0} has more than 1 '{1}' option.")
不幸的是，我只能将部分格式化的消息传递给客户端验证消息，并且我这样做：
var rule = new ModelClientValidationRule
{
ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()),
ValidationType = "noduplicatestringvalues",
};
在运行验证之前，验证不会知道哪个选项值是重复的，所以我想在验证功能期间完成消息格式化。
但是，似乎只能在 $.validator.unobtrusive.adapters.add() 函数期间设置错误消息。
我尝试在验证期间在 select 元素上设置 data-val-noduplicatestringvalues 属性，但错误消息仍然显示如下：
FieldName has more than 1 '{ 1}' 项。
有什么方法可以更改验证功能期间的错误消息吗？
I have a multiple select listbox in an MVC3 form. A user can add & remove custom option elements to and from this listbox. However I want to validate that no 2 options in the listbox contain the same value.
I have created a custom ValidationAttribute that implements IClientValidatable. Both the server and the client validation are working. However, my ErrorMessage looks like this:
ErrorMessage = "{0} has more than 1 '{1}' option.")
Unfortunately I can only pass a partially formatted message to the client validation message, and I do it like so:
var rule = new ModelClientValidationRule
{
ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()),
ValidationType = "noduplicatestringvalues",
};
The validation won't know which option value is duplicated until the validation is run, so I want to complete the message formatting during the validation function.
However, it seems that the error message can only be set during the $.validator.unobtrusive.adapters.add() function.
I have tried setting the data-val-noduplicatestringvalues attribute on the select element during the validation, but the error message is still displayed like so:
FieldName has more than 1 '{1}' item.
Is there any way to change the error message during the validation function?

您可以自定义消息。
如果您查看
jquery.validate.js中的remote验证方法，您将看到一个自定义错误消息的示例，在这种情况下使用从远程返回的消息验证功能。You can customize the message.
If you look at the
remotevalidation method injquery.validate.js, you will see an example of customizing the error message, in that case using a message returned from a remote validation function.
