地图的removeChild (mapQuest)

Question

当用户单击“后退”按钮时，我试图关闭地图。

我正在为Adobe应用程序使用AS3。

为了关闭函数，我尝试用removeChild(MyMap)调用一个函数，但是它不能工作(错误#2025:提供的显示对象必须是调用方的子函数)。

你知道我该怎么做吗？

这是我的密码：

var MyMap:TileMap = new TileMap("KEY_OF_MAP");
addChild(MyMap);

VisibleButton();

}        

function VisibleButton():void
{
    var skip:MovieClip;
    skip = new skype
    addChild(skip);
    skip.addEventListener(MouseEvent.CLICK, closeMap, false, 0, true);
}

function closeMap(e:MouseEvent):void
{
    trace("ferme carte");
    var MyMap:TileMap = new TileMap("KEY_OF_MAP");
    removeChild(MyMap);
}

编辑:

所以，我会给你尽可能多的细节。

我将代码直接放入场景中，如下所示：

​

在第11张图片中，我编码了一个名为"goMapButton“的按钮。行动守则是：

goMapButton.addEventListener(MouseEvent.CLICK, callDisplayMap, false, 0, true);

function callDisplayMap(event:MouseEvent):void{
    displayMap();
}

在我的第12张图片中，我得到了一个动作代码：

stop();

            this.stage.scaleMode = StageScaleMode.NO_SCALE;

            // create a new TileMap object, passing your platform key



            var myMap:TileMap = new TileMap("Fmjtd%7Cluur2g0an0%2C2s%3Do5-9azwdr");

              embeddedIconPoi.icon = myIcon;
              myMap.addShape(embeddedIconPoi);

VisibleButton();

          }

              skip.addEventListener(MouseEvent.CLICK, closeMap, false, 0, true);

          }

//I'd like to close the map when the user click on the skip button

          function closeMap(e:MouseEvent):void{
              var myMap:TileMap = new TileMap("Fmjtd%7Cluur2g0an0%2C2s%3Do5-9azwdr");
              trace("ferme carte");
              trace(myMap.parent == null);


          }

首先删除：

var MyMap:TileMap = new TileMap("KEY_OF_MAP");

因为您已经准备好在第一行代码中启动map实例。

我不认为你会需要它后，第一次修复，但如果你仍然有错误，你可以用这个代替。

MyMap.parent.removeChild(MyMap);

如下所示：

stop();

    import flash.display.MovieClip;
    import flash.display.Sprite;
    import flash.display.StageScaleMode;
    import com.mapquest.tilemap.*;
    import com.mapquest.LatLng;
    import com.mapquest.tilemap.pois.*;
    import com.mapquest.services.directions.Directions;
import com.mapquest.services.directions.DirectionsConstants;
import com.mapquest.services.directions.DirectionsEvent;
import com.mapquest.services.geocode.Geocoder;
import com.mapquest.services.geocode.*;
import com.mapquest.services.geocode.GeocoderEvent;
import com.mapquest.services.geocode.GeocoderLocation;
import com.mapquest.tilemap.Size;
import flash.display.Bitmap;
import com.mapquest.tilemap.TileMap;
import com.mapquest.tilemap.controls.inputdevice.MouseWheelZoomControl;
import com.mapquest.tilemap.controls.shadymeadow.SMLargeZoomControl;
 import com.mapquest.tilemap.controls.shadymeadow.SMViewControl;

// create a new TileMap object, passing your platform key
 var myMap:TileMap = new TileMap("Fmjtd%7Cluur2g0an0%2C2s%3Do5-9azwdr");

function displayMap():void{
    trace("displaying Map");
            //turn scaling off
            this.stage.scaleMode = StageScaleMode.NO_SCALE;







                        myMap.size = new Size(800, 533);
            myMap.addControl(new SMLargeZoomControl());
            myMap.addControl(new MouseWheelZoomControl());
            myMap.setCenter(new LatLng(-21.060478, 164.861113),12);     



            //add the map to the sprite.
            addChild(myMap);

var myPoi:Poi;
                  //ICONES BATTERIES
             [Embed (source="huiles.png")] 
            var HuilesImg:Class;
            var embeddedIconPoi:Poi;

              var myIcon:MapIcon = new MapIcon();

                myIcon.setImage(new HuilesImg(),22,32);
              embeddedIconPoi = new Poi(new LatLng(-11.71199, 12.647725));
              embeddedIconPoi.rolloverAndInfoTitleText = "Info about that place";
              embeddedIconPoi.icon = myIcon;
              myMap.addShape(embeddedIconPoi);

VisibleButton();

          }      

//This function makes a button visible at the left corner of the screen
function VisibleButton():void{
              var skip:MovieClip;
              skip = new skype
              addChild(skip);
              skip.addEventListener(MouseEvent.CLICK, closeMap, false, 0, true);

          }

//I'd like to close the map when the user click on the skip button

          function closeMap(e:MouseEvent):void{

              trace("ferme carte");
              trace(myMap.parent == null);

              if (myMap.parent == this)
              {
                   removeChild(myMap);
              }
          }
