【问题描述】：
我使用第 2 版已经有一段时间了，并决定是时候将第 3 版作为主要网站更新的一部分。我所有的代码都基于“Mike Williams' tutorial The Basics - Part 3: Loading the data from an XML file translated to v3”。经过数小时的微调，我完成了所有工作，包括聚类和自定义标记。
我是一只非常快乐的兔子，并且热衷于炫耀它。然后令我失望的是，我发现它在 IE 或 Firefox 中都不起作用（我一直在 Chrome 中测试它）。
我很清楚 Google Maps API 不是一件容易使用的东西，但是有什么理由让我应该在不同的浏览器上获得这种行为？前往www.littlehotels.co.uk/new/ 并点击“地图搜索”即可查看地图。代码在这里：
