但它没有缩放以适应标记。标记正从数据库加载到脚本。我需要在地图上设置其中心点，并且必须占据地图中的所有标记。请告诉我错过的地方。

您正在扩展侦听器内的边界。尝试移动
mybounds.extend(latlng[i]);
在听众之外
mybounds.extend(latlng[i]);
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent('<b>'+locations[i][0]+'</b></br>'+locations[i][3]);
infowindow.open(map, marker);
}
})(marker, i));
，您的latlng数组不包含与您的位置数组一样多的位置，因此您将无法拟合地图中的所有位置，仅适用于latlng。
