我正在使用带参数的html.actionlinks ....我有一个简单的例子，其中值来自模型工作....
然而，对于一个actionLink，我从devexpress网格动态获取值。
对于另一种形式，我让它工作，我动态获取值并将其传递给HTML.BeginForm
鉴于这两个例子，我不明白我在下面做错了什么......
这个工作：
@using EtracsWeb.Areas.IO.Models;
@model VoyageInputModel
<script type="text/javascript">
//var voyage_ids;
function OnSelectionChanged(s, e) {
s.GetSelectedFieldValues("VoyageID", GetSelectedFieldValuesCallback);
}
function GetSelectedFieldValuesCallback(values) {
// voyage_ids = values;
//alert(voyage_ids);
document.getElementById('VoyageIDS').value = values;
}
</script>
@using (Html.BeginForm("Index", "Voyage",
new { VoyageID = 0, Model.VoyageIDS, Model.ShowReceivedVoyages, Model.ETADate, Model.VoyageReceivedDate }))
{
<div class="divTable" >
<div class="divTableRow">
<div class="divTableCell"> <input type="submit" value="Receive" name="ReceiveVoyage" /> </div>
<div class="divTableCell"> @Html.TextBoxFor(model => model.VoyageReceivedDate, new{ @class = "date" }) </div>
</div>
</div>
@* Gets the selected values from the grid and stores it in HTML so that beginForm can access*@
@Html.Hidden("VoyageIDS", Model.VoyageIDS)
}
注意......我没有显示devExpress Grid，但它正在调用OnSelectionChanged javascript ...
这是我的第二个代码示例，现在使用ActionLinks。在这个例子中，我让它用于传递Model.VIN，它正在Get action ....上设置但是我在调用Manage WorkOrder Action链接时得到零，该链接试图使用Model.WorkOrderID设置的方式与我在第一个示例中设置Model值的方式相同....
@using EtracsWeb.Areas.Vehicle.Models
@model VehicleVinInquiryData
@{
ViewBag.Title = "VinInquiry";
Layout = "~/Views/Shared/_LayoutMenu.cshtml";
}
@* MUST go here and NOT at end or code won't work *@
<script type="text/javascript">
//var wo_id;
function OnSelectionChanged(s, e) {
s.GetSelectedFieldValues("WorkOrderID", GetSelectedFieldValuesCallback);
}
function GetSelectedFieldValuesCallback(values) {
// alert(values);
// wo_id = values;
document.getElementById('xWorkOrderID').value = values;
// document.getElementById('xxID').value = values;
alert(document.getElementById('xWorkOrderID').value);
}
</script>
@using (Html.BeginForm("VinInquiry", "Info"))
{
<div class="divTable" >
<div class="divTableRow">
<div class="divTableCell"> <label>VIN</label> </div>
<div class="divTableCell"> @Html.TextBoxFor(m => m.VIN) </div>
<div class="divTableCell"> <input type="submit" value="Display" /> </div>
<div class="divTableCell"> <input type="submit" value="Clear" /> </div>
<div class="divTableCell">
<ul id="nav">
<li>
<a href="#">Actions</a>
<ul>
<li>@Html.ActionLink("Send an Email" , "Index" , "Email" , new { Area = "IO" } , null)</li>
<li>@Html.ActionLink("Attach a File" , "AttachFile" , "Management" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("Add a Comment" , "Create" , "Comment" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("Add Allocation" , "Create" , "Allocation" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("Change Allocation" , "Edit" , "Allocation" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("Delete/Cancel Allocation" , "Delete" , "Allocation" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("View Dealers" , "List" , "Dealer" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("Change HotRush Status" , "EditHotRushStatus" , "Management" , new { Area = "Vehicle" } , null)</li>
<li>@Html.ActionLink("Relocate Vehicle (Pass VehicleID)" , "RelocateVehicle" , "Location" , new { Area = "Vehicle" ,VIN=Model.VIN } , null)</li>
<li>@Html.ActionLink("View Service Requests (Pass VehicleID" , "Index" , "ServiceRequest" , new { Area = "Vehicle" ,VIN=Model.VIN } , null)</li>
<li>@Html.ActionLink("Create a Voyage-Ship Entry" , "AddVoyageShipEntry", "Voyage" , new { Area = "IO" } , null)</li>
<li>@Html.ActionLink("Process Manager" , "ProcessManager" , "Management" , new { Area = "IO" } , null)</li>
<li>@Html.ActionLink("Manage WorkOrder (pass WorkOrderID)" , "Index" , "WorkOrderManagement", new { Area = "WorkOrder" , WorkOrderID=Model.WorkOrderID } , null)</li>
</ul>
</li>
</ul>
</div>
</div>
</div>
@* <input type="text" value="xxID" name="xxID" /> *@
@Html.Hidden("xWorkOrderID" , Model.WorkOrderID)
}
警报正在运行，所以我知道值正在进入隐藏变量......
作为替代方案，我可以使用以下内容获取在javascript中生成的整个actionLink：
<script type="text/javascript">
var wo_id;
function OnSelectionChanged(s, e) {
s.GetSelectedFieldValues("WorkOrderID", GetSelectedFieldValuesCallback);
}
function GetSelectedFieldValuesCallback(values) {
// alert(values);
wo_id = values;
document.getElementById('sWorkOrderID').value = values;
alert(document.getElementById('sWorkOrderID').value);
var atext = '@Html.ActionLink("Manage WorkOrder", "Index", "WorkOrderManagement", new { Area = "WorkOrder" , WorkOrderID="xxx" } , null)'.replace('xxx', wo_id);
alert(atext);
$("#myTag") = atext;
}
</script>
但是我无法弄清楚如何将这个新的actionlink的值恢复到html ....我知道这是基本的javascript ....但是我使用什么标签？我的actionlink位于
<li> create the action link here </li>
答案 0 :(得分：1)
您不能将服务器端帮助器Html.ActionLink()与隐藏值一起使用。您正在尝试在首次呈现页面后更新客户端上的链接标记。
你最后一次尝试几乎就在那里。试试这个：
<ul>
<li><!-- initially this is just a placeholder link -->
@Html.ActionLink("Manage WorkOrder", "Index", "WorkOrderManagement",
routeValues: new { Area = "WorkOrder" , WorkOrderID=Model.WorkOrderID },
htmlAttributes: new { id="workorderlink" })
</li>
</ul>
function GetSelectedFieldValuesCallback(values) {
var wo_id = values;
$("#xWorkOrderID").val(values); // update hidden input
var link = $("#workorderlink");
var oldhref = link.attr("href");
var newhref = oldhref.substring(0, oldhref.lastIndexOf('/')) + "/" + wo_id;
link.attr("href", newhref); // update the link
}
回调抓取原始href，然后使用新动态获取的值替换网址中的WorkOrderId值。
注意：看来你正在使用jquery，所以我保持一致并使用jquery样式而不是getElementById。
