如何在asp.net core中使用jquery验证ckeditor？

我想验证所需的ckeditor，当它为空且用户提交表单时，它应该向用户显示一条消息以填充描述。我搜索了很多，但没有一个解决方案有效。这是jquery：

$(document).ready(function () {

        $("#formTicket").validate(
            {
                ignore: [],
                debug: false,
                rules: {
                    Description: {
                        required: function () {
                            CKEDITOR.instances.Description.updateElement();
                        }
                    }
                },
                messages:
                {
                    Description: {
                        required: "Please enter Text"
                    }
                }
            });
    });

这是html：

  <form id="formTicket" asp-action="NewTicket" asp-controller="Ticket" method="post" 
          enctype="multipart/form-data">
                       
                        <div class="row">
                            <div class="col-md-12">
                                <div class="form-group">
                                    <label>توضیحات*</label>
                                    <textarea rows="5" class="form-control" asp-for="Description"> 
                        </textarea>
                                    <span asp-validation-for="Description" class="text-danger"> 
                            </span>

                                </div>
                            </div>
                        </div>
                       
                        <input type="submit" id="submitButton" class="btn btn-info btn-fill pull- 
                         right" onclick="return confirm('آیا از ارسال مطمئن هستید؟')" 
                   name="submitButton" value="ارسال">
                        <div class="clearfix"></div>
                    </form>

您是否添加了这些脚本

<script src="https://cdn.ckeditor.com/4.16.0/standard/ckeditor.js"></script>
<script src="~/lib/jquery-validation/dist/jquery.validate.min.js"></script>
<script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.min.js"></script>

从您的代码中，您是否真正应用了ckeditor？您应该将“class=ckeditor”添加到文本区域

而的asp应替换为名称和id

这是我的演示：

<form id="formTicket" asp-action="NewTicket" asp-controller="Ticket" method="post"
  enctype="multipart/form-data">
<div class="row">
    <div class="col-md-12">
        <div class="form-group">
            <label>توضیحات*</label>
            <textarea rows="5" class="ckeditor" name="Description" id="Description" > </textarea>
            <span asp-validation-for="Description" class="text-danger">
            </span>
        </div>
    </div>
</div>
<input type="submit" id="submitButton" class="btn btn-info btn-fill pull-
                     right" onclick="return confirm('آیا از ارسال مطمئن هستید؟')"
       name="submitButton" value="ارسال">
<div class="clearfix"></div>
 </form>


@section Scripts
{
<script src="https://cdn.ckeditor.com/4.16.0/standard/ckeditor.js"></script>
<script src="~/lib/jquery-validation/dist/jquery.validate.min.js"></script>
<script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.min.js"></script>
<script type="text/javascript">
    $(document).ready(function () {

        $("#formTicket").validate(
            {
                ignore: [],
                debug: false,
                rules: {
                    Description: {
                        required: function () {
                            CKEDITOR.instances.Description.updateElement();
                        },
                        minlength: 10
                    }
                },
                messages:
                {
                    Description: {
                        required: "Please enter Text",
                        minlength: 10
                    }
                }
            });
    });
</script>
}

توضیحات*
@节脚本
{
$（文档）.ready（函数（）{
$（“#格式票证”）。验证(
{
忽略：[]，
调试：错误，
规则：{
说明：{
必需：函数（）{
CKEDITOR.instances.Description.updateElement（）；
},
最小长度：10
}
},
信息：
{
说明：{
必填：“请输入文本”，
最小长度：10
}
}
});
});
}
