Google Map API的polyline问题

[AstaChen]

在地图上有两个标记marker1和marker2,polyline1是以marker1和marker2为顶点的一条折线,用鼠标移动marker1或marker2时,要使polyline1也跟着相应的移动...

不知道怎么写marker的drag事件,各位支个招,谢谢.

function GoAddMovePoint()
{
MovePointCounter=2;
MoveMarkers = [];

for (i = 0; i < MovePointCounter; i++)
{
createMarker(i);
}
var point1=MoveMarkers[0].getLatLng();
var point2=MoveMarkers[1].getLatLng();

polyline = new GPolyline([point1,point2], "#ff0000", 10);
mapx.addOverlay(polyline);
}

function createMarker(i)
{
var initPt = mapx.fromContainerPixelToLatLng(new GPoint((i + 1) * 30, 50));

MoveMarkers.push(new GMarker(initPt, { draggable: true }));

mapx.addOverlay(MoveMarkers[i]);
}

定义marker的dragend事件，重新创建一个polyline并添加到地图上就可以

虽已解决,仍感谢phinix_c

GEvent.addListener(MoveMarkers[i], "dragend", function() {
mapx.removeOverlay(polyline);
polyline = new GPolyline([MoveMarkers[0].getLatLng(), MoveMarkers[1].getLatLng()
], "#ff0000", 5);
mapx.addOverlay(polyline);
});
