我正在为我的组织开发一个应用程序，该应用程序需要在地图上显示其办公位置，当用户单击链接时，应用程序将在浏览器上打开谷歌地图并显示用户当前位置和所选办公标记之间的路线。这在 Android 应用程序中运行良好，但不适用于 iPhone/iPad 应用程序。我正在使用以下代码：
我已经在 index.html 文件中声明了 google api 脚本
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
下面是 location.html 文件的代码
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">

<body style="display: none; background-color: silver; color: green; font-size: small;">
<div data-role="main" class="ui-content">
<div data-role="content" id="contentMap">
<div id="map_canvas" style="position: absolute !important; top: 10px !important; right: 0; bottom: 5px !important; left: 0 !important;"></div>
</div>
</div>
<script src="js/location.js"></script>

以下是 location.js 文件的代码：

this.latitude = latitude;
this.longitude = longitude;

this.address = address;
