如何在Google api v3中获取Rectangle div贴图

Question

如何在default或bounds_changed事件时获得4个角（lat＆amp; lng）

Answer 1

这应该可以，将它放在一个在bounds_changed事件处理程序中调用的函数中：

var bounds = map.getBounds();
var northEastCorner = bounds.getNorthEast();
var southWestCorner = bounds.getSouthWest();

var northWestCorner = {
    lat: northEastCorner.lat(),
    lng: southWestCorner.lng()
};

var southEastCorner = {
    lat: southWestCorner.lat(),
    lng: northEastCorner.lng()
};
