Question

我有这个模型：

public class TutorialBindingModel
{
    [Required]
    [RegularExpression(@"[A-Za-z0-9\ \-_]+", ErrorMessage = "You are using invalid characters")]
    [StringLength(128, ErrorMessage = "The {0} must be max 128 characters long.")]
    public string Title { get; set; }

    public List<SampleBindingModel> Samples { get; set; }
}

public class SampleBindingModel
{
    [Required]
    [StringLength(64, ErrorMessage = "The {0} must be max 64 characters long.")]
    [RegularExpression(@"[A-Za-z0-9\ \-_]+", ErrorMessage = "You are using invalid characters")]
    public string Name { get; set; }

    [Required]
    [StringLength(512, ErrorMessage = "The {0} must be max 64 characters long.")]
    [RegularExpression(@"[A-Za-z0-9\ \-_]+", ErrorMessage = "You are using invalid characters")]
    public string Description { get; set; }

}

当我填写教程时，有一个按钮可以创建带有合适字段的新示例表单。样本表单是模型为SampleBindingModel的局部视图，因此我仅将asp-for放在字段上并在name上更改Samples[0].Name。而且我得到正确的标记，其中嵌套模型的字段在html中具有验证属性：

<input class="item" name="Samples[0].Name" placeholder="Text" type="text" data-val="true" data-val-length="The Name must be max 64 characters long." data-val-length-max="64" data-val-regex="You are using invalid characters" data-val-regex-pattern="[A-Za-z0-9\ \-_]+"
  data-val-required="The Name field is required." id="Name" value="">
<span data-valmsg-for="Samples[0].Name" class="field-validation-valid" data-valmsg-replace="true"></span>

但是问题是我无法验证此样本表单。正确验证了主模型，但未验证嵌套模型。我认为这是因为我动态创建示例表单，并且需要在此表单上设置验证器，但我不认为该怎么做

解决方案很简单。问题是，当我使用jquery验证器创建新示例时，不知道新字段，因此我删除了验证器，并在创建示例时再次对其进行了初始化

$("form").removeData("validator").removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse("form");

嵌套模型的JQuery验证
