Я не могу на всю жизнь понять, почему этот постбэк иногда делает ajax так, как предполагается, а иногда нет.Вот соответствующий код:
JS:
<html>
<head>
<title>Index</title>
<link href="/Content/screen.css" rel="stylesheet" type="text/css" />
<!--[if lt IE 8]><link href="/Content/ie.css" rel="stylesheet" type="text/css" /><![endif]-->
<link href="/Content/plugins/fancy-type/screen.css" rel="stylesheet" type="text/css" />
<link href="/Content/plugins/buttons/screen.css" rel="stylesheet" type="text/css" />
<link href="/Content/plugins/link-icons/screen.css" rel="stylesheet" type="text/css" media="screen, projection" />
<link href="/Content/jQueryUI/css/cupertino/jquery-ui-1.8.9.custom.css" rel="stylesheet" type="text/css" />
<link href="/Content/HelpDesk.css" rel="stylesheet" type="text/css" />
<link href="/Content/droppy.css" rel="stylesheet" type="text/css" />
<link href="/Content/tablesorter.css" rel="stylesheet" type="text/css" />
<script src="/Scripts/jquery-1.4.4.min.js" type="text/javascript"></script>

<script src="/Scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>

<script type='text/javascript'>
$(function () {
$('#nav').droppy();
});
</script>
<script type="text/javascript">
$(document).ready(function () {
$("#targetStartDate").datepicker();
$("#targetEndDate").datepicker();
$("#ticketsHTMLTable").tablesorter({ sortList: [[0, 0], [1, 0]] });
$(".fakeLink").mouseover(function () {
$(this).css("color", "red");
});
$(".fakeLink").mouseout(function () {
$(this).css("color", "black");
});
});
</script>
</head>
Вот мой взгляд (бритва):
@using (Ajax.BeginForm("Index", "Problem", new AjaxOptions
{
HttpMethod = "GET",
UpdateTargetId = "ticketsTable",
InsertionMode = InsertionMode.Replace
}))
{
<div class="notice">
<div class="prepend-1 span-2">
<label for="targetPriorityID">
Priority</label>
</div>
<div class="prepend-1 span-3">
<label for="targetStatusID">
Status</label>
</div>
<div class="span-3">
<label for="targetBusinessUnitID">
Business Unit</label>
</div>
<div class="span-3 prepend-1">
<label for="targetStartDate">
Start Date</label></div>
<div class="span-3 prepend-2">
<label for="targetEndDate">
End Date</label></div>
<div class="prepend-1 span-3 last">
 
</div> <div class="prepend-1 span-2">
@Html.DropDownList("targetPriorityID",
new SelectList(ViewBag.Priorities as System.Collections.IEnumerable,
"ID", "Title"), "All", new { @onchange = " this.form.submit();" })
</div>
<div class="prepend-1 span-3">
@Html.DropDownList("targetStatusID",
new SelectList(ViewBag.Statuses as System.Collections.IEnumerable,
"ID", "Title"),"All", new { @onchange="this.form.submit();" })
</div>
<div class="span-3">
@Html.DropDownList("targetBusinessUnitID",
new SelectList(ViewBag.BusinessUnits as System.Collections.IEnumerable,
"ID", "Title"), "All", new { @onchange = "this.form.submit();" })
</div>
<div class="span-3 prepend-1">@Html.TextBox("targetStartDate", "", new { onchange = "this.form.submit();" })</div>
<div class="span-3 prepend-2">@Html.TextBox("targetEndDate", "", new { onchange = "this.form.submit();" })</div>
<div class="prepend-1 span-3 last">
<input type="submit" value="Hide" />
</div>
<br />
<br />
<br />
</div>
}
<div id="ticketsTable">
@Html.Partial("_AllTickets", Model)
</div>
И, наконец, контроллер,
[HttpPost]
public ActionResult Index(int targetPriorityID = -1, int targetBusinessUnitID = -1, int targetStatusID = -1, string targetStartDate = "", string targetEndDate ="")
{
Repository<Priority> priorityRepository = new Repository<Priority>();
Repository<BusinessUnit> businessUnitRepository = new Repository<BusinessUnit>();
Repository<Status> statusRepository = new Repository<Status>();
ViewBag.Priorities = priorityRepository.GetAll();
ViewBag.BusinessUnits = businessUnitRepository.GetAll();
ViewBag.Statuses = statusRepository.GetAll();
var results = problemRepository.GetAll();
results = (targetPriorityID != -1) ? results.Where(t => t.PriorityID == targetPriorityID) : results;
results = (targetBusinessUnitID != -1) ? results.Where(t => t.BusinessUnitID == targetBusinessUnitID) : results;
results = (targetStatusID != -1) ? results.Where(t => t.StatusID == targetStatusID) : results;
results = (targetStartDate != "") ? results.Where(t => t.DateReported >= DateTime.Parse(targetStartDate)) : results;
results = (targetEndDate != "") ? results.Where(t => t.DateReported <= DateTime.Parse(targetEndDate)) : results;
if (Request.IsAjaxRequest())
{
return PartialView("__AllTickets", results);
}
return View(results);
}
Есть мысли?
