单击批准按钮时，如何将所有带有值的模型属性传递给批准索引操作？

问：

我正在开发一个 ASP.NET MVC 应用程序。我遇到了一个问题，即单击“批准”按钮时无法将模型属性值传递给操作方法。ResignationRequesterApproveIndex

所有属性，例如和加载详细信息页面加载时，然后我写评论，然后单击“批准”按钮保存。Request noemployee noSpeakStuffCommentSpeakStuffCommentrequest no

单击“批准”按钮时，如何将模型传递给操作方法？ResignationRequesterApproveIndex

@model HR.WorkforceRequisition.Models.ResignationRequester

@{
    ViewBag.Title = "Details";
    Layout = "~/Views/Shared/_LayoutResignation.cshtml";
}

<div style="padding-top:10px;">

    @if (!string.IsNullOrEmpty(ViewBag.msg))
    {
        <div class="alert alert-success">
            @ViewBag.msg
        </div>
    }
   
    @if (ViewBag.AllowApprove == true)
    {
        
      using (Html.BeginForm("ApprovalIndex", "Resignation", FormMethod.Post, htmlAttributes: new { @style = "display:inline;" }))
{
    @Html.AntiForgeryToken()
    
    <a onclick = "$(this).parents('form:first').submit();" class="btn btn-primary" style="min-width: 100px; 
    margin-left: 5px;"><i class="glyphicon glyphicon-ok"></i> Approve </a>
}
    <table style="border: 1px solid black;width:100%;">   
        <tr>
            <td class="hover" style="font-weight: bold; padding-top: 10px;">
                <div class="form-group hover">
                    @Html.LabelFor(model => model.RequestNo, htmlAttributes: new { @class = "control-label col-md-5" })
                    <div class="col-md-7">
                        @Model.RequestNo
                    </div>
                </div>
            </td>
        </tr>
        <tr>
            <td class="hover" style="width: 50%; font-weight: bold; padding-top: 10px;">
                @Html.LabelFor(model => model.EmpName, htmlAttributes: new { @class = "control-label col-md-5" })
                <div class="col-md-7">
                    @Model.EmpName
                </div>
            </td>
            <td class="hover" style="font-weight: bold; padding-top: 10px;">
                @Html.LabelFor(model => model.EmpID, htmlAttributes: new { @class = "control-label col-md-5" })
                <div class="col-md-7">
                    @Model.EmpID
                </div>
               
            </td>
        </tr>
    </table>

    <table style="border: 1px solid black;width:100%;">
        <tr>   
            <td class="hover" style="font-weight: bold; padding-top: 10px;">
                <div class="form-group hover">
                    @Html.Label("If yes, why did the staff resign? If No, Why? ", htmlAttributes: new { @class = "control-label col-md-5" })
                    <div class="col-md-7">
                        @Html.EditorFor(model => model.SpeakStuffComment, new
                        {
                            htmlAttributes = new
               { @class = "form-control" }
                        })
                    </div>
                </div>
            </td>
        </tr>
    </table>
</div>

法典：

public class ResignationRequester
{
    [Display(Name = "Employee No : ")]
    [Required,]
    public int EmpID { get; set; }

    [Display(Name = "Request No")]
    public int RequestNo { get; set; }

    [Required]
    [Display(Name = "Emp. Name: ")]
    public string EmpName { get; set; }

    [DataType(DataType.MultilineText)]
    public string SpeakStuffComment { get; set; }
}

批准索引操作，如下所示：

public class ResignationController : Controller
    {
        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> ApprovalIndex(ResignationRequester REQ)
        {
             return new EmptyResult();
       }
}

调用 API 时，它命中操作结果断点，但值显示为 null 我在代码上的问题高于所有属性值，如显示 null - 请问如何解决这个问题？SpeakStuffComment and Request no

从调试断点开始，我检查了模型 Resignation Requester 的属性值，尽管它有数据，但它显示所有属性值都为 null。

那么什么是问题以及如何解决它呢？
