Question

在我看来，这就是我所拥有的

        @foreach (var match in Model.CommonMatches)
        {
            <tr>

                <td>@match.StartDateTime</td>
                <td>@match.EndDateTime</td>
                <td>@match.AvailableAttendees.Count()</td>
                <td>@Html.ActionLink("Accept", "AcceptAppointment", "Appointment", new {commonMatch = @match })</td>
            </tr>
        }

Model.CommonMatches的类型为List<Window>

public class Window
{
    public DateTime StartDateTime { get; set; }
    public DateTime EndDateTime { get; set; }
    public IEnumerable<DataModels.Attendee> AvailableAttendees { get; set; }

}

这是从控制器传递值的方式

[HttpGet]
public ActionResult ViewStatus(Guid appointmentId)
{
    var status = new ViewStatus
    {
        AttendeesWhoResponded = _appointmentRepository.GetAppointmentDetails(appointmentId).Attendees.Where(a=>a.HasResponded == true).ToList(),
        NotAttending = _appointmentRepository.GetAppointmentDetails(appointmentId).Attendees.Where(a=>a.HasResponded == true && a.Responses == null).ToList(),
        CommonMatches = _appointmentRepository.FindCommonMatches(appointmentId)
    };
    return View(status);
}

ViewStatus类

public class ViewStatus
{
    public ViewStatus()
    {
        AttendeesWhoResponded = new List<DataModels.Attendee>();
        NotAttending = new List<DataModels.Attendee>();
    }
    public List<DataModels.Attendee> AttendeesWhoResponded { get; set; }

    public List<DataModels.Attendee> NotAttending { get; set; }
    public IEnumerable<Window> CommonMatches { get; set; }
}

视图的ActionLink调用的控制器中的操作是：

[HttpGet]
public ActionResult AcceptAppointment(Window commonMatch)
{
    return Content("ac");
}

当我在控制器的操作中检查commonMatch的值时。我收到StartDateTime和EndDateTime，但我没有得到AvailableAttendees的全部价值。目前显示为null。

我期待的AvailableAttendees类型为IEnumerable<Attendee>。是不可能按照我传递的方式传递对象？

我该怎么做，还要在控制器中获取AvailableAttendees的所有值以及日期？

<table class ="table-hover table-striped">
    <thead>
        <tr>
            <td>Start time</td>
            <td>End time</td>
            <td>Number of Attendees</td>
        </tr>
    </thead>


            @for (var count = 0; count < Model.CommonMatches.Count();count++ )
            {
                using (Html.BeginForm("AcceptAppointment", "Appointment", FormMethod.Post))
                {
                    <tr>
                        <td>@Model.CommonMatches[count].StartDateTime</td>
                        <td>@Model.CommonMatches[count].EndDateTime</td>
                        <td>@Model.CommonMatches[count].AvailableAttendees.Count()</td>
                        @*<td>@Html.ActionLink("Accept", "AcceptAppointment", "Appointment", new { commonMatch = @match })</td>*@


                    @for(var j=0;j<Model.CommonMatches[count].AvailableAttendees.Count();j++)
                    {
                        <td>@Model.CommonMatches[count].AvailableAttendees[j].FirstName</td>//to check if the value is null or not, just a test
                        <td>@Html.HiddenFor(m=>Model.CommonMatches[count].AvailableAttendees[j].FirstName)</td>
                        <td>@Html.HiddenFor(m=>Model.CommonMatches[count].AvailableAttendees[j].LastName)</td>
                        <td>@Html.HiddenFor(m=>Model.CommonMatches[count].AvailableAttendees[j].Email)</td>
                        <td>@Html.HiddenFor(m=>Model.CommonMatches[count].AvailableAttendees[j].AttendeeId)</td>
                    }
                        <td><input type="submit" value="Accept"/></td>
                     </tr>

                }
            }

Answer 1

您需要将模型发回，这将涉及将控制器方法更改为：

<强>控制器

[HttpPost]
public ActionResult AcceptAppointment(List<Window> model)
{
    return Content("ac");
}

查看

您需要一个表单和一个提交按钮而不是ActionLink。我已将表格格式化为简化以下内容。

使用for循环索引集合，以便模型绑定器知道如何处理它们，这实际上是两个循环，因为它是集合中的集合。隐藏的值也必须被渲染回来（请原谅任何错别字）。

@for(var i = 0; i < Model.CommonMatches.Count; i ++) { <div> @using (Html.BeginForm("AcceptAppointment", "Appointment", FormMethod.Post) { @Html.HiddenFor(m => Model.CommonMatches[i].StartDateTime) @Html.HiddenFor(m => Model.CommonMatches[i].EndDateTime) @Model.CommonMatches[i].StartDateTime <br/> @Model.CommonMatches[i].EndDateTime <br/> @for(var j = 0; Model.CommonMatches[i].AvailableAttendees.Count; j++) { @Html.HiddenFor(m => Model.CommonMatches[i].AvailableAttendees[j].Prop1)<br/> @Html.HiddenFor(m => Model.CommonMatches[i].AvailableAttendees[j].Prop2)<br/> } <input type="submit" value="Accept" /> </div> } }

Answer 2

你需要照顾很多事情

<td>@Html.ActionLink("Accept", "AcceptAppointment", "Appointment", new {commonMatch = @match })</td>

呼叫

[HttpGet]
public ActionResult AcceptAppointment(Window commonMatch)
{
    return Content("ac");
}

您在此处使用链接<a href>进行导航。基本上你发出了一个get请求。在get请求中，您只能通过Query String将数据传递到服务器。但是你的情况是，在导航到url之前动态准备一个查询字符串有点复杂。但是你可以使用像onclick=prepareHref(this);

这样的JavaScript来实现

@Html.ActionLink("Accept", "AcceptAppointment", "Appointment", 
  new {commonMatch = @match }, new {onclick=prepareHref(this)})

然后在Javascript中

function prepareHref(obj)
{
 var qsData="?StartDateTime='2014-02-25'&EndDateTime='2014-02-25'&AvailableAttendees[0].prop1=value1, etc"; // data should be obtained from other td elements
 obj.href=obj.href+qsData;
}

但这并不是建议的做法。

如果你想打开其他页面并显示网址，最好再次传递id并加载数据。

选项1：

更好的方法是在@hutchonoid解释隐藏字段中提交细节。

选项2：

或者在jQuery ajax $.post方法中提交详细信息。您需要使用POST

@Html.ActionLink("Accept", "AcceptAppointment", "Appointment", 
  new {commonMatch = @match }, new {onclick=postMyData()})


function postMyData(){
    var postData={};
    postData.StartDateTime='';
    postData.EndDateTime='';
    postData.AvailableAttendees=[];
    //for each AvailableAttendees prepare object
    postData.AvailableAttendees[0]= {};
    postData.AvailableAttendees[0].prop1=value1;



    $.post('/Appointment/AcceptAppointment/',{data:postData},function(data){

    });
    return false;
}

[HttpPost]
public ActionResult AcceptAppointment(Window commonMatch)
{
    return Content("ac");
}

传递实体，从视图到控制器
