c# - 如何获取 data-id 发送到另一个控制器 mvc

Question

如何将数据 ID 发送到 ASP.NET MVC 中的另一个控制器？

员工提交表格，自动确定id和部门职位，然后发送给经理审批。

经理在此页面上单击批准或拒绝，并将表单发送给下一个人进行批准。这一步页面提示id=null不能运行。我应该怎么办？

但是谷歌后台显示我得到了这个Id，如何发送这个Id到action？

public PartialViewResult saveStatus(int id, string Status, string AddDate, string Remark)
{
    int approvalId;

    if (id == 0 && Session["AppId"] == null)
    {
        var staff = db.Staffs.Where(s => s.UserName == User.Identity.Name).FirstOrDefault();

        RequestForApproval ap = new RequestForApproval
                    {
                        RequestToStaffId = staff.Id,
                        RequestDate = DateTime.Now,
                    };

        db.RequestForApprovals.Add(ap);
        db.SaveChanges();

        Session["AppId"] = ap.ReimbursementID;
        approvalId = ap.Id;
    }
    else
    {
        approvalId = int.Parse(Session["AppId"].ToString());
    }

    ApprovalStatus temp = new ApprovalStatus
                {
                    Id = approvalId,
                    Remark = Remark,
                    AddDate = DateTime.Now
                };

    db.ApprovalStatuses.Add(temp);
    db.SaveChanges();

    var df = db.ApprovalStatuses.Where(s => s.Id == approvalId).ToList();
    return PartialView(df);
}

public JsonResult CreateStatus()
{
    List<ApprovalStatus> mv = new List<ApprovalStatus>();

    if(Session["AppId"] == null)
    {
        ViewBag.Ae = 0;
    }
    else
    {
        ViewBag.Ae = Session["AppId"];
        int approvalId = int.Parse(Session["AppId"].ToString());
        mv = db.ApprovalStatuses.Where(s => s.Id == approvalId).ToList();
    }

    return Json(mv);
}

public ActionResult AddRequestForApproval()
{
    // var staffUser = db.StaffPositions.Where(a => a.Staff.UserName == System.Web.HttpContext.Current.User.Identity.GetUserId());
    var rmid = Session["RmId"].ToString();

    if (string.IsNullOrEmpty(rmid))
    {
        return RedirectToAction("Index");
    }

    int reimbursementId = int.Parse(rmid);
    Session["RmId"] = null;

    var Res = db.Reimbursements.Find(reimbursementId);
    var managerId = GetByStaffId(Res.StaffId,reimbursementId);

    RequestForApproval temp = new RequestForApproval();
    temp.ReimbursementID = reimbursementId;
    temp.RequestDate = DateTime.Now;
    temp.RequestToStaffId = managerId;

    db.RequestForApprovals.Add(temp);
    db.SaveChanges();

    return RedirectToAction("Index");
}

看法：

@model Reimbursements.Models.RequesViewModel

@{
        ViewBag.Title = "Index";
        var add = Session["AppId"];
}

<h2>Index</h2>

<table class="table" id="table1">
        <tr>
            <th></th>
            <th>

            </th>
            <th>
                RequestDate
            </th>
            <th></th>
        </tr>

        @foreach (var item in Model.GetReApproval)
        {
            <tr>
                <td>
                    <a href="~/Reimbursements/GetOtherDetails/@item.ReimbursementId">@item.ReimbursementId</a>

而不是放在data-id那里，您可以将其作为隐藏文件的值放入表单中，以便在提交表单时发布：

<input type = "hidden" name="id" value="@item.ReimbursementId" />

如果在单击不同按钮时值可能会发生变化，您希望发送不同的值，那么您可以隐藏输入并在提交之前设置其值：

$('#Submit').click('#enumId', function () {
    var bid = $(this).data('id');
    $('[name="id"]').val(bid);
    // rest of your code....
});

编辑：如果您要使用 ajax 发布它，请注意您应该获得如下数据：

$(this).data('id');
