Question

很奇怪。当我在我的本地计算机上预览我的地图文件时，它工作得很好并且标记出现。但是，当我上传到我的Web服务器时，标记会消失。文件完全一样......

有谁知道发生了什么事？

Answer 1

它适用于Chrome，Firefox和IE8。也许你的浏览器缓存中有一个糟糕的xml副本（你正在使用哪个浏览器？）

Answer 2

尝试使用您自己的合法密钥。这一行

<script src="http://maps.google.com/maps/api/js?sensor=false"
        type="text/javascript"></script>

应该看起来像这样

<script type="text/javascript"
      src="http://maps.googleapis.com/maps/api/js?key=AacbdefglcdK7C2GHbQAmdkBID70Uppuf-D030&sensor=true">
    </script>

您可以在自己的主页上申请自己的Google Maps API密钥。由于有关带宽等情况，常规用户不允许使用默认Google密钥发布的原因有几个。因此，大量公司必须付费才能获得Google地图密钥的许可，但是为了您的使用，免费密钥可能会正常工作。

当我上传到我的网络服务器时，谷歌地图v3上的标记消失了
