Question

我刚开始使用Google Maps API进行开发，所以我经常会看到一些错误。现在我在方向服务中实现地理编码器时遇到了问题。例如，我有这个错误：

Uncaught InvalidValueError: in property origin: not a string; and not a LatLng or 

LatLngLiteral: not an Object main.js:13
(anonymous function) main.js:13

OQ.(anonymous function).ji VM2948:10
(anonymous function) main.js:35

Mg.(anonymous function).route main.js:35
calcRoute new%20%205.html:67
onchange

这是我的代码。

我的任务是创建一个地图，显示从位置（当前位置）到地址（将从数据库中检索）的路线，人们可以一次选择运输。如果应用程序无法获得用户的当前位置，则用户可以输入他/她的位置。那么也许有人可以帮我解决这个问题？
