Question

我正在阿根廷实施具有不同路线的自定义KML。

我想显示我的自定义ExtendedData，但不起作用。有人可以告诉我是什么问题吗？

这是我的代码KML

那是我的KML代码，那是我在MyMaps中尝试的结果

这是Google向我显示的结果：

您看到的问题是KML无效。 KML中的标签区分大小写。 KML使用大小写混合的标记，有时以大写字母开头，而其他时候则以小写字母开头（例如const text = '2018-11-15T11:13:26.687Z' const [y, m, d, hh, mm, ss, ms] = text.split(/[-T:.Z]/); const date = new Date(Date.UTC(y, m - 1, d, hh, mm, ss, ms)); console.log(date.toLocaleString()); // date string in local timezone console.log(date.toUTCString()); // UTC date string console.log(JSON.stringify(date)); // ISO 8601 date string in most browsers，<Data>等），因此您必须验证正确的语法。在Google Earth Pro中显示KML可能有助于检查KML是否正确，并按您期望的方式显示。

<value>元素必须为小写的<Value>，StyleUrl元素必须以小写字母开头；即<value>。

更改地标，使其看起来像这样：

<styleUrl>

出于某种原因，Document父容器上的说明也阻止了地标的显示，因此建议从Document中删除description元素或仅对其进行注释。

如何在KML文件中显示自定义ExtendedData？
