javascript - 写入kml文件: How send kml string to kml file?

Question

我有一个项目，可以在 map 上绘制并生成 kml 作为字符串。我想通过 ajax 请求将其发送到 kml 文件。

$.ajax({
    type: 'PUT',
    url: 'myurl.kml',
    data: kmlString,
    success() {
       //say it succeeded
    }
});

因为我的 kml 数据嵌套在引号内，就像这样，

'<xml.....</kml>'

kml 文件提示由于引号而导致语法不正确(这是事实)。

我想过将数据作为 json 对象而不是字符串传递，就像这样，

{'mapData': 'mykmldata'}

但数据仍然用引号封装。

将我的数据获取到不带引号的 kml 文件的最佳方法是什么？ Google map API v3 似乎在任何地方都没有“字符串到 kml”功能，尽管我觉得这在这种情况下是万能的。

我注意到 Google Earth API 有一个 parseKml 函数，它与谷歌地图兼容吗？

Answer 1

第三方 KML 解析器 geoxml3有一个“parseKmlString”方法，该方法将从字符串中获取有效的 KML 并解析它以创建 native Google Maps Javascript API v3 对象。

示例: 从此文件中获取 KML: http://www.geocodezip.com/geoxml3_test/kml/MA_cities.kml
