Question

我有一个自动打开的信息窗口。

我希望只有两个自动打开，而一个没有。效果就像在图片中一样。我的代码：

identifierForVendor

Picture 1 = so now

Picture 2 = so it has to be

Answer 1

我建议你对它进行概括，在数组中添加一个成员以确定是否打开标记。

var locations = [
    // IW content, lat, lng, nowrap, open IW
    ['Oddział', 52.846190, 17.723237, 3, true],
    ['Oddział', 52.812224, 17.201023, 2, true],
    ['Zakład Poligraficzny - Siedziba', 52.847942, 17.757889, 1, false]       
];

然后这样打开infowindow：

if (locations[i][4]) {
  google.maps.event.trigger(marker, 'click');
}

  var bounds = new google.maps.LatLngBounds();

  for (i = 0; i < locations.length; i++) {
    var marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2], locations[i][3]),

    var infowindow = new google.maps.InfoWindow();
