如何在asp.net核心mvc中验证JavaScript创建的元素

public class JavaScriptCreatedAttribute : ValidationAttribute, IClientModelValidator
{
    public void AddValidation(ClientModelValidationContext context)
    {
        // 添加客户端验证规则
        context.Attributes.Add("data-val", "true");
        context.Attributes.Add("data-val-javascriptcreated", ErrorMessage);
    }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        // 执行服务器端验证逻辑
        // 在此处编写验证 JavaScript 创建的元素的代码
        // 如果验证失败，返回 ValidationResult
        // 如果验证成功，返回 ValidationResult.Success
    }
}

public class YourModel
{
    [JavaScriptCreated(ErrorMessage = "验证失败的错误消息")]
    public string JavaScriptCreatedElement { get; set; }
}

<form asp-action="YourAction" method="post">
    <input type="text" id="yourElement" name="yourElement" />
    <span asp-validation-for="yourElement" class="text-danger"></span>
    <input type="submit" value="提交" />
</form>
