Question

如何獲得4角落（LAT & LNG）時默認或bounds_changed事件，

Answer 1

這應該工作，把它放在一個被調用你的bounds_changed事件函數內處理者：

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() 
};
