我刚刚复制了这个问题的代码并应用了我的纬度和经度.然而,纬度和经度将是动态的,并且center地图的位置将根据位置的纬度和经度而改变.
以下是其他问题的代码

所以我的问题是,在拥有动态位置时,我怎么能知道地图的中心.我试过center留空,但地图没有加载.

首先,您可以通过包含所有动态生成的位置来创建LatLngBounds对象.使用extend方法包含点.然后,您可以使用getCenter方法获取绑定的中心.
更新:
码:
var bound = new google.maps.LatLngBounds();
for (i = 0; i < locations.length; i++) {
bound.extend( new google.maps.LatLng(locations[i][2], locations[i][3]) );
// OTHER CODE
}
console.log( bound.getCenter() );
