leaflet - 在 this.map.fitBounds 之前预测缩放级别

Question

我在我们的应用程序中使用 mapbox。执行 this.map.fitBounds(bound value) 将缩小或放大 map 以绑定(bind)指定值。在调用 this.map.fitBounds 之前，我需要找出缩放级别(即拟合边界后的 map 渲染)。 mapbox 中是否有可用的方法？

Answer 1

使用L.Map的getBoundsZoom方法:

Returns the maximum zoom level on which the given bounds fit to the map view in its entirety. If inside (optional) is set to true, the method instead returns the minimum zoom level on which the map view fits into the given bounds in its entirety.
