KML / Google Map - 在iFrame中指定嵌入式地图的缩放级别 [英] KML / Google Map - Specifying the zoom level of an embeded map in an iFrame

问题描述

我在Google map中加载了以下kml文件，它正确地定位了指针，但它总是放大到最高级别。

使用google地图API我可以设置自己的缩放级别，但我正尝试在iFrame中使用嵌入式地图（由Google提供）来执行此操作。

有没有办法在kml中设置缩放级别？我看了一下LookAt和Camera属性，但是文档说它们在Google Map中不受支持。

谢谢！

解决方案

您可以通过参数控制Google地图的显示行为传递iframe元素的src - 在你的情况下通过设置z参数 - 请参阅此处

只需将您的iframe源代码设为 http://maps.google.com/?ll=48.064372,16.348977&z=10 并将z = 10更改为其他更高（最高20）或更低值（低至0）

或者，在Maps API中，您可以使用 setCenter（）函数来设置缩放级别

I have the following kml file that I am loading in Google map, it's locating the pointer correctly however the it's always zoomed at the maximum level.

Using the google map APIs I can set my own zoom level but I am trying to do this using an embedded map in an iFrame (provided by google).

Are there anyways to set the zoom level in the kml itself? I had a look at LookAt and the Camera attribute but the doc say they aren't supported in Google Map.

Thanks!

解决方案

You can control Google Map's display behaviour by the arguments you pass in the src of the iframe element - in your case by setting the "z" parameter - see here

simply make your iframe source as "http://maps.google.com/?ll=48.064372,16.348977&z=10" and change z=10 to any other higher (up to 20) or lower value (down to 0)

Alternatively, in the Maps API you would use the setCenter() function to set the zoom level
