如何在Google Maps API中添加移动标记的信息窗口？

Question

我正在创建一个项目，我想在其中添加信息窗口，以便在Google地图API中移动标记。 I have added info window as shown in image 但是我无法在船上添加相同的东西。

在线标记代码：

for (var i = 0; i < DrivePath.length-1; i++) {
  var line = new google.maps.Polyline({
    path: [DrivePath[i], DrivePath[i+1]],
    icons: [
    {
      icon: symbolShape,
      offset: '0%'
    }
    ],
    strokeColor: Colors[i],
    strokeOpacity: 0.0,
    strokeWeight: 2,
    map: map
  });
  lineArray[i] = line;

  google.maps.event.addListener(line, 'click', function() {
    infowindow.open(map,line);
  });
}

for (var i = 0; i < DrivePath.length-1; i++) {
  line1 = new google.maps.Polyline({
    path: [DrivePath[i], DrivePath[i+1]],
    icons: [
    {
      icon: symbolSource,
      offset: '0%'
    }, {
      icon: symbolDestination,
      offset: '100%'
    }
    ],
    strokeColor: Colors[i],
    strokeOpacity: 1.0,
    strokeWeight: 2,
    map: map
  });
  lineArray1[i] = line1;
}

console.log(lineArray.length);
console.log(lineArray1.length);

  //Map boundaries
  var bounds = new google.maps.LatLngBounds();
  for (var i = 0; i < line.getPath().getLength(); i++) {
    bounds.extend(line.getPath().getAt(i));
  }
  map.fitBounds(bounds);

整个代码都在 JSFiddle.
