Question

我第一次使用DirectionsManager在Bing Maps AJAX v7中创建路线。路线创建正确，但附带两个小的“信息框”，在路线的开头显示“A”，最后显示“B”。我想删除那些信息框，但老实说，在阅读完所有文档（http://msdn.microsoft.com/en-us/library/hh312832.aspx）和“Binging / Google搜索”一段时间之后，我找不到任何有用的信息。另外，我尝试了setRenderOptions中的每个选项。有什么想法吗？

        directionsManager = new Microsoft.Maps.Directions.DirectionsManager(map);
        directionsManager.resetDirections();
        directionsManager.setRenderOptions({autoDisplayDisambiguation: false, 
            autoUpdateMapView: true, displayManeuverIcons: false, displayPreItineraryItemHints: false, displayPostItineraryItemHints: false, displayRouteSelector: false, displayStepWarnings: false, drivingPolylineOptions: { strokeColor: new Microsoft.Maps.Color(150, 255, 51, 51), strokeThickness: 8 }
        });

        directionsManager.setRequestOptions({ routeMode: Microsoft.Maps.Directions.RouteMode.driving });

        var seattleWaypoint = new Microsoft.Maps.Directions.Waypoint({ address: '000 fake street, Houston TX 77000' });
        directionsManager.addWaypoint(seattleWaypoint);
        var tacomaWaypoint = new Microsoft.Maps.Directions.Waypoint({ address: '111 fake street, Houston TX 77111' });
        directionsManager.addWaypoint(tacomaWaypoint);

        directionsManager.calculateDirections();

一种可能的解决方案是自定义图钉以显示小尺寸的空白图钉（我尝试使用尺寸为15x15像素的另一个图钉）：

// Set the render options
            directionsManager.setRenderOptions({ 
                itineraryContainer: document.getElementById('itineraryDiv'), 
                displayWalkingWarning: false, 
                walkingPolylineOptions:{strokeColor: new Microsoft.Maps.Color(200, 0, 255, 0)},
                waypointPushpinOptions: {icon:'pin_blank.png', height:1, width:1}
            });

另一种方式可能是自己调用服务并在代码中处理请求和响应。以下是一个示例：http://msdn.microsoft.com/en-us/library/gg427607.aspx
