将文字添加到Google地图 [英] Add text to Google Maps
问题描述
使用API V3时，如何在Google地图的右下角添加文字或超链接。也就是说，在下面的屏幕截图中显示的地图数据（c）2014 Google旁边添加文本或超链接。
How can I add text or hyper-links to the bottom right of Google Maps when using API V3. That is, add text or hyper-links next to "Map data (c)2014 Google" shown in the screen shot below.
以下是我的代码：
Here is my code:
<!DOCTYPE html>
<html>
<head>
<title>EC Bus Locations</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">

margin: 0px;
padding: 0px
}

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>

});
}

推荐答案
解决方案实际上非常简单，标记图标的图像。作为Google Chart Tools的一部分，您可以生成包含字母或数字的标记，还可以更改标记和字体颜色。

The solution is actually quite simple and simply involves you using an image for the marker icons. As part of Google Chart Tools you can generate markers that contain a letter or number, as well change the marker and font colors.
