Google地图是否改变了允许脚本访问它的方式？我问的原因是我有几个运输计算器的网站使用jquery和json来计算使用谷歌地图的邮政编码之间的距离。
问题可以在这里看到：
http://www.sos-motorcycle-recovery.co.uk/
在“获取和即时报价”部分下，如果您输入几个邮政编码，让我们说PE219PX，然后在结束旅程NG323RJ，通常会返回总距离和成本，但它没有做任何事情，并且这也发生在另一个使用相同脚本的网站上，这让我想知道谷歌是否改变了什么？问题是我没有看到任何错误，所以我甚至不确定从哪里开始。
运行它的代码看起来像这样：
<div class="key4-module-inner">
<div class="module-content"><script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&sensor=false&key=AIzaSyDfnkRoxyEYmXSgY_Dne74TaBAfglq5Lxk"></script>

我刚看了谷歌API v2网站，它说：
警告：Google Maps JavaScript API的第2版不再可用。请按照指南将您的代码迁移到Google Maps JavaScript API的第3版。截至2013年11月19日，所有请求v2的应用程序都将提供v3 API的特殊包装版本。我们希望API的这个包装版本适用于大多数简单的地图，但我们强烈建议您立即迁移到v3 API。
我现在正在摸不着头脑，因为我不确定如何将它转换为API v3
