Marker()需要谷歌地图API传递与position和lng按键，都具有数字值的lat对象。你的情况，你必须拥有myPos和Lat（大写）的对象Lng，和你得到，因为myPos.lat === undefined错误。
有，你有可能现在想通了，在拼写小discrepency这是导致错误您所遇到。正确的拼写是lat和lng〜所有小写，而不是资本。这就是说，通过使用parseFloat(var)或使用谷歌地图的方法new google.maps.LatLng(_LAT_,_LNG_)打电话时他们也不会伤害投下变量数
因为我有一点点空闲时间我打得四处略微原始代码，你会看到如下 - 希望它帮助。
