[英]google maps api v3 zoom_changed event fired twice after fitBounds called
[英]Google Maps API fitBounds() behaves differently if called after resize event
我正在使用google maps api在具有移动和桌面视图的网站上显示飞行路线。 如果显示宽度小于320px,则移动视图将隐藏包含的div(显示:无)。 如果用户将手机转到横向模式,则div以及地图将变为可见。 但是,如果以横向模式加载页面,则与页面以纵向模式加载(未显示地图)然后旋转到横向相比,地图显示另一个缩放级别。 调整大小事件被触发,在其中,我称之为fitBounds()。 任何想法??

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

谢谢,克莱曼
尝试禁用Google API的默认用户界面。 我认为您的地图没有在人像上平移。 该片段显示了用于禁用它的模板。 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); }
