javascript - 如果在 resize 事件后调用 Google Maps API fitBounds() 行为会有所不同

Question

我正在使用 google maps api 在具有移动和桌面 View 的网站上显示飞行路径。如果显示宽度低于 320 像素，移动 View 会隐藏包含的 div(显示:无)。如果用户将手机切换到横向模式，则 div 和 map 将变得可见。
但是，如果我以横向模式加载页面，则 map 显示另一个缩放级别，而不是以纵向模式加载页面(未显示 map )然后旋转为横向。调整大小事件被触发，我在其中调用 fitBounds()。任何的想法？？

var bounds = new google.maps.LatLngBounds(null);
var map = null;
var myLatLng = null;

function initialize() {

  var mapOptions = {
    panControl: true,
    scaleControl: false,
    overviewMapControl: false,

    path: destinations,
    geodesic: true,
    strokeColor: '#FF0000',
    strokeOpacity: 1.0,

  });

  flightPath.setMap(map);

  for (var i = 0; i < destinations.length; i++) {
    var myTitle = destinations[i].myTitle;
    myLatLng = new google.maps.LatLng(destinations[i].lat, destinations[i].lng);
    var marker = new google.maps.Marker({
        position: myLatLng,

    var label = new Label({
       map: map
    });
    label.bindTo('position', marker, 'position');
    label.bindTo('text', marker, 'text');
    bounds.extend(marker.position);
  }
  map.fitBounds(bounds);
  if(map.getZoom() == 0) map.setZoom(1);
}

google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, "resize", function() {
     google.maps.event.trigger(map, "resize");
     map.fitBounds(bounds);
     //alert("Resize Event fired");

    });

尝试禁用 Google API 的默认 UI。我认为您的 map 没有在纵向上平移。该片段显示了禁用它的模板。希望能帮助到你。

function initialize() {
  var mapOptions = {
    zoom: 4,
    center: new google.maps.LatLng(-33, 151),
    disableDefaultUI: true
  }
  var map = new google.maps.Map(document.getElementById("map-canvas"),
       mapOptions);
}
