Chrome下使用百度地圖報錯Cannot read property 'minZoom' of undefined

問題：工作中在Google chome下面的js console里面測試百度地圖API

var map = new BMap.Map("container");

map.centerAndZoom(new BMap.Point(116.404, 39.915), 11);
 
TypeError: Cannot read property 'minZoom' of undefined
message: "Cannot read property 'minZoom' of undefined"
stack: (...)
get stack: function () { [native code] }
set stack: function () { [native code] }
__proto__: Error

解決辦法：把js代碼放到地圖DIV容器的下面即可。
