验证错误消息未显示在Asp.Net Core 2 MVC部分视图中

我有一个索引页面,其中列出了“工作簿”标题,每个工作簿都有一个“共享”按钮。当按下按钮时,会出现一个引导程序模型(即对话框),该模型显示工作簿的标题和文本区域,允许用户输入共享电子邮件地址。

当用户按下“共享”按钮时,我正在调用一个javascript函数,该函数调用一个控制器操作,该操作返回一个包含模式对话框的局部视图,该模式对话框中包含表单。问题是,在按下提交按钮(即“共享”)之后,没有验证错误显示给用户,我不确定为什么会这样。有人可以提供一些想法吗?

enter image description here

这是我的主要( index.cshtml )页面:

@model DNAAnalysisCore.Models.WorkBookModel
@{
}

@section BodyFill
{
    <script type="text/javascript">

        function showSharingView(title) {
            var url = "@Url.Action("ShowShareDialog", "Home")" + "?workbookTitle=" + encodeURI(title);
            $('#shareFormContainer').load(url,
                function() {
                    $('#shareFormModal').modal("show");
                });
        }

        function hideSharingView() {
            $('#shareFormModal').modal("hide");
        }

    </script>

    <div id="shareFormContainer" >
       <!--PLACEHOLDER FOR SHARE DIALOG -->
    </div>

    <div class="workbook-container">
        <table class="table">
            <tbody>
            @foreach (var workbook in Model.Workbooks)
            {
                <tr>
                    <td>@Html.ActionLink(workbook.Name, "Open", "OpenAnalytics", new {id = Model.Id, workbook = workbook.Name})</td>
                    <td>
                        <button title="Share" class="share-button" onclick='showSharingView("@workbook.Name")'>&nbsp;</button>
                    </td>
                </tr>
            }
            </tbody>
        </table>
    </div>
}

那是我的控制器:

public class HomeController : Controller
{
    [HttpGet]
    public IActionResult ShowShareDialog(string workbookTitle)
    {
        var shareModel = new ShareModel
        {
            Title = workbookTitle
        };

        return PartialView("_ShareView", shareModel);
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public IActionResult ShareWorkbook(string emails, string title)
    {
        var share = new ShareModel
        {
            Emails = emails
        };

        // TODO EMAIL THE SHARED WORKBOOK using the 'title' of the workbook and the 'email' string value

        // return no content to avoid page refresh
        return NoContent();
    }
}

这是我的局部视图/模式对话框(_ShareView):

@using DNAAnalysisCore.Resources
@model DNAAnalysisCore.Models.ShareModel

<!-- Modal -->
<div class="modal fade" id="shareFormModal" role="dialog">
    <div class="modal-dialog modal-md">
        <!-- Modal content-->
        <div class="modal-content">
            <div class="modal-header">
                <h4 class="modal-title">Share Workbook - @Model.Title</h4>

            </div>

            @using (Html.BeginForm("ShareWorkbook", "Home", FormMethod.Post))
            {
            <div class="modal-body">

                <label>@BaseLanguage.Share_workbook_Instruction_text</label>
                <div class="form-group">
                    <textarea class="form-control" asp-for="Emails" rows="4" cols="50" placeholder="@BaseLanguage.ShareDialogPlaceholder"></textarea>
                    @* TODO add client-side validation using jquery.validate.unobtrusive.js. See US268276 *@
                    <span asp-validation-for="Emails" class="text-danger"></span>
                </div>

                <input asp-for="Title" />
            </div>
            <div class="modal-footer">
                <button type="submit" onclick="hideSharingView()" class="btn btn-primary">Share</button>
                <button id="btnCancelDialog" type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
            </div>
            }

        </div>
    </div>
</div>


@section Scripts {
    @{ await Html.RenderPartialAsync("_ValidationScriptsPartial"); }
}

这是我的 ShareModel

public class ShareModel
{
    [HiddenInput]
    public string Title { get; set; }
    [Required]
    public string Emails { get; set; }
}

页面加载时不会将表单添加到页面上,不打扰的验证也不会进行。简单的解决方案是使用#define concat(x, y) concat_i(x, y) #define concat_i(x, y) x##y #define concat_if(cond, x, y) concat(concat_if_, cond)(x, y) #define concat_if_0(x, y) (x) #define concat_if_1(x, y) concat(x, y) int concat_if(1, hello, 0); //int hello0; int concat_if(0, hello, 1); //int (hello); 。请参考here

1。在$.validator.unobtrusive.parse("#id-of-the-form");部分视图中将id添加到表单:

_ShareView

2。将验证文件@using (Html.BeginForm("ShareWorkbook", "Home", FormMethod.Post,new { @id="partialform"})) 引入主页(Index.cshtml),并使用不干扰用户的验证手动注册表单。

_ValidationScriptsPartial.cshtml
