我已经设法在我的一张地图上实现了“信息框”,这些地图加载了mySQL数据库中保存的位置,但我想对此进行一些更改,但我不确定如何。
我正在使用的代码如下,但我希望能够替换信息框的“默认”行为,即在地图加载时出现在每个标记旁边,信息框仅出现一次单击标记,平移以将地图置于该标记的中心。然后,当单击下一个标记时,信息框将从第一个标记移动到新单击的标记,再次使用平移和中心功能。

我还想在更改颜色,边距等方面更多地了解信息框,但我只在http://google-maps-utility-library-v3.googlecode.com/svn/tags/infobox/1.1.5/docs/reference.html找到了不太详细的指导。我希望。还有其他地方我可以去获取更详细的信息吗?
现在已经解决了,代码正在运行。
