Question

我正在将c＃和ASP.NET MVC4用于Web应用程序（使用移动模板）。我的详细信息视图页面出现问题。（首先从索引页面选择一些内容，然后转到详细信息页面）我在页面上放置了一个bing地图，并且没有加载地图。首先我认为地图有问题，但不是。我注意到网址是 http://localhost:2550/Place/Details 的页面。但是，如果我手动将“1”放在最后，那么http://localhost:2550/Place/Details/1 然后地图加载到页面上。我不明白为什么会这样......

有谁知道为什么？感谢

我的详细信息页面视图：

@model Project.Models.Place
@{ ViewBag.Title = "Details";}
<h2>Place Details</h2>
<fieldset>
<div class="display-label"> Name: @Model.Name</div>
<div class="display-label">Address: @Model.Address</div>
<div class="display-label">Post Code: @Model.PostCode</div>
<div class="display-label"> PhoneNo: @Model.PhoneNo</div>
</fieldset>

<p>    @Html.ActionLink("Back to List", "Index")</p>

<body onload="getMap();">
  <div id='myMap' style="position:relative; width:400px; height:400px;"></div>
  <div>
     <input type="button" value="createWalkingRoute" onclick="createDirections();" />
  </div>
  <div id='directionsItinerary'> </div> 
</body>

@section scripts{

 <script type="text/javascript"    src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script>
  <script type="text/javascript">
      var map = null;
      var directionsManager;
      var directionsErrorEventObj;
      var directionsUpdatedEventObj;

      function getMap() {
          map = new Microsoft.Maps.Map(document.getElementById('myMap'), { credentials: 'mykey' });
      }

      function createDirectionsManager() {
          var displayMessage;
          if (!directionsManager) {
              directionsManager = new Microsoft.Maps.Directions.DirectionsManager(map);
              displayMessage = 'Directions Module loaded\n';
              displayMessage += 'Directions Manager loaded';
          }
          alert(displayMessage);
          directionsManager.resetDirections();
          directionsErrorEventObj = Microsoft.Maps.Events.addHandler(directionsManager, 'directionsError', function (arg) { alert(arg.message) });
          directionsUpdatedEventObj = Microsoft.Maps.Events.addHandler(directionsManager, 'directionsUpdated', function () { alert('Directions updated') });
      }

      function createWalkingRoute() {
          if (!directionsManager) { createDirectionsManager(); }
          directionsManager.resetDirections();
          // Set Route Mode to walking 
          directionsManager.setRequestOptions({ routeMode: Microsoft.Maps.Directions.RouteMode.walking });
          var seattleWaypoint = new Microsoft.Maps.Directions.Waypoint({ address: 'Seattle, WA' });
          directionsManager.addWaypoint(seattleWaypoint);
          var redmondWaypoint = new Microsoft.Maps.Directions.Waypoint({ address: 'Redmond, WA', location: new Microsoft.Maps.Location(47.678561, -122.130993) });
          directionsManager.addWaypoint(redmondWaypoint);
          // Set the element in which the itinerary will be rendered
          directionsManager.setRenderOptions({ itineraryContainer: document.getElementById('directionsItinerary') });
          alert('Calculating directions...');
          directionsManager.calculateDirections();
      }

      function createDirections() {
          if (!directionsManager) {
              Microsoft.Maps.loadModule('Microsoft.Maps.Directions', { callback: createWalkingRoute });
          }
          else {
              createWalkingRoute();
          }
      }
  </script>

}

我的控制器操作细节：

    public ViewResult Details(int id)
    {
        ViewBag.events = eventRepository.PlaceEvents(id);
        return View(placeRepository.Find(id));
    }

Answer 1

可能的原因，可能是您没有用Zero参数编写Controller默认控制器。

或者您还没有使用[HttpPost]属性

编写控制器

如果你把控制器的代码放在这里会很容易。

Answer 2

如果您说最后使用/ 1的导航有效，但您当前的网址没有数字，那么您在索引页面上的网址是错误的。您的网址现在就像

@Html.ActionLink("Details", "Place")

将其更改为：

@Html.ActionLink("Details", "Place", new { id = @Model.Id })

所以问题是您的ID没有提供给您的详细信息。

视图页面和网址中存在错误
