Question

我试图在调用fitbounds（确定正确的缩放级别）后禁用缩放。我尝试设置最小和最大缩放值，但它不起作用。这是我的代码：

var bounds = new google.maps.LatLngBounds(
        //south, west
        new google.maps.LatLng(minLat, minLon), 
        //north, east
        new google.maps.LatLng(maxLat, maxLon)
);
map.fitBounds(bounds);
currentZoom = map.getZoom();
map.setOptions({maxZoom: currentZoom, minZoom: currentZoom});

为了说清楚，我要禁用的是鼠标缩放。

谢谢

Answer 1

map.fitBounds是异步的，您需要为zoom_changed事件添加事件侦听器。

google.maps.event.addListenerOnce(map, 'zoom_changed', function () {
    currentZoom = map.getZoom();
    map.setOptions({
        maxZoom: currentZoom,
        minZoom: currentZoom
    });
});

var maxLat = 40.735657;

#map_canvas {
  height: 100%;
  width: 100%;
  margin: 0px;
  padding: 0px

<div id="map_canvas" style="border: 2px solid #3872ac;"></div>

Answer 2

只需查看documentation。

禁用滚轮，按钮，然后双击缩放：

map.setOptions({zoomControl: false, scrollwheel: false, disableDoubleClickZoom: true});
