我最近将我正在使用的 PhoneGap/Cordova 版本更新为最新版本。我的应用程序中有一个页面在每次加载时都会抛出以下错误。
未捕获的引用错误：未定义 google
我尝试使用直接来自谷歌开发者网站的示例网页来尝试缩小我的选择范围，但在尝试在手机上加载该页面时仍然出现相同的错误。（在这里找到：https ://developers.google.com/maps/documentation/javascript/examples/map-simple ）。我应该注意，当在我的桌面上的 Chrome 中将这个网页作为 .HTML 文件从谷歌运行时，它运行良好。
我也尝试使用此处找到的解决方案：Google Maps API throws "Uncaught ReferenceError: google is not defined" only when using AJAX
但是，甚至从未调用过初始化方法，这使我相信这是我仍然缺少的脚本标签的问题。
据我所知，我在我的 HTML 中使用了正确的脚本调用：
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?<KEY>&sensor=false"></script>
并且崩溃的javascript代码如下：
origins[0] = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
完整代码在这里：
