Question

我试着使用示例代码来拥有一个网页，以便在地图上显示多个图钉。

这是我的HTML代码：

((imgSomeFile).Source as BitmapImage).UriSource.OriginalString

诀窍是使用带参数的url来添加要显示的位置：

Ex：http://myserver.com?q=MyFirstPoint@59.591,17.82

实际上没有显示任何内容..

有人可以帮我吗？我的API密钥在代码上;）

非常感谢，

致以最诚挚的问候，

Answer 1

你有一个

 callback=initMap

但我看不到这个名字的功能

和你有类似的

<body onunload="GUnload()">

但我看不到这个名字的功能

你必须小心谨慎，你可以调用正确的init函数来显示地图，并在浏览器控制台中查看其他错误

Answer 2

Q = MyFirstPoint @ 59.591,17.82＆安培; Q = MyLastPoint @ 54.591,12.82
