嘿伙计们，我正试图将一个项目放在一起以增加我对 MVC3 的了解，但我碰壁了......
因此，从我的索引“视图”中的 HolidaysController，我创建了一个超链接，它将用户导航到“create3”ActionResult
@Html.ActionLink("选择 3 个日期", "Create3")在我的 create3 页面中，我希望用户在文本框中输入 3 个日期，当他们单击“创建”时，用户将返回到以前的 HolidaysController/Index 页面，日期将按日期升序显示
....ATM 我一直在工作，直到用户输入 3 个日期并单击“创建”...但是我只知道如何显示一个显示订单的消息框，它正在工作我只需要帮助才能获得订单从索引页面显示。
请看我的代码：
HolidayController/索引的代码：
//submit will go to post
[HttpPost]
public ViewResult Index(int HolidayDate)
{
var holidays = db.Holidays.Include("Person");
HolidayList model = new HolidayList();
model.currentPersonID = HolidayDate;
model.PList4DD = db.People.ToList();
model.Categories = holidays.Select(x => new SelectListItem
{
Value = x.Id.ToString(),
Text = x.Person.Name
}
);
int data = HolidayDate;
model.HList4DD = db.Holidays.Where(h => h.PersonId == HolidayDate).ToList();
return View(model);
}
[HttpGet]
public ViewResult Index(string sortOrder, int? currentPersonID)
{
var holidays = db.Holidays.Include("Person");
HolidayList model = new HolidayList();
//not null
if (currentPersonID.HasValue)
{
model.currentPersonID = currentPersonID.Value;
}
else
{
model.currentPersonID = 0;
}
model.PList4DD = db.People.ToList();
ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "date" : "";
var dates = from d in db.Holidays
where d.PersonId == currentPersonID.Value
select d;
switch (sortOrder)
{
case "date":
dates = dates.OrderBy(p => p.HolidayDate);
break;
}
model.HList4DD = dates.ToList();
return View(model);
}
//View for Index
@*@model IEnumerable<HolidayBookingApp.Models.Holiday>*@
@model HolidayBookingApp.Models.HolidayList
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<p>
@Html.ActionLink("Select 3 Dates", "Create3")
</p>

@foreach (var item in Model.HList4DD)
{

<script>
function updateFormEnabled()
{
if (verifyAdSettings())
{
$('#sbmt').removeAttr('disabled');
}
else
{
$('#sbmt').attr('disabled', 'disabled');
}
}
function verifyAdSettings()
{
if ($('#HolidayDate').val() != '')
{
return true;
}

{
return false;

$('#HolidayDate').change(updateFormEnabled);

<div>
Judging by your selection the order of dates are: //HERE IS WHERE I WANT TO DISPLAY THE ORDER OF DATES
</div>
</table>
就在上面是我想按顺序显示日期的地方，升序

and my view:
@model HolidayBookingApp.Models.Dates
@{
ViewBag.Title = "Create3";
}
<h2>Create3</h2>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<legend>Dates</legend>
<div class="editor-label">

</div>
<div class="editor-field">

<div class="editor-label">

<div class="editor-field">

<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>"Index")
</div>
不确定从这里去哪里，比如在索引视图中创建一个拉过订单的参数？
任何帮助都会非常感谢你们，对这篇文章感到抱歉
