Leaflet 传单在点击一个簇时会放大很多倍
传单现在缩放得如此之快,而不是点击一个簇。 一个标记的一小部分显示在地图的右侧,另一个标记的一小部分显示在地图的左侧 我的解决方法是在范围内计数标记,并在计数器=0时重新调整zoomlevel。 这不应该在传单的动物计算中吗 缩放校正:Leaflet 传单在点击一个簇时会放大很多倍,leaflet,Leaflet,传单现在缩放得如此之快,而不是点击一个簇。 一个标记的一小部分显示在地图的右侧,另一个标记的一小部分显示在地图的左侧 我的解决方法是在范围内计数标记,并在计数器=0时重新调整zoomlevel。 这不应该在传单的动物计算中吗 缩放校正: mcg.on('clusterclick', function () { if (markersInScope == 0) { var zoom = map.getZoom(); ma
mcg.on('clusterclick', function () {
if (markersInScope == 0) {
var zoom = map.getZoom();
map.setZoom(zoom - 1);
}
});
您可以尝试调整缩放以适应mcg的边界,并添加一些填充
mcg.on('clusterclick', function () {
map.fitBounds(mcg.getBounds().pad(0.5));
}
});
