我從here 得到谷歌地圖繪製折線的代碼,但我想根據經度和緯度得到地圖的重點,所以我加了這條線 - > map.setCenter(新的google.maps.LatLng(-122.5868225097656,45.56117947133065)); 但折線沒有出現由於緯度和經度的屏幕和我加入(map.setCenter)行沒有任何改變 這裏外面是代碼:專注於谷歌地圖API根據經緯度

是無效的latlong(s)。這就是爲什麼應用程序不能正常工作的原因。

我試圖互換這些值。並且工作得很好。

map.setCenter(new google.maps.LatLng(45.56117947133065,-122.5868225097656)); 
    var flightPlanCoordinates = [ 
    new google.maps.LatLng(45.56117947133065,-122.5868225097656), 
    new google.maps.LatLng(45.493833740092185,-122.6348876953125) 
    ];
