我在 Jquery Mobile 中做一个项目并且遇到了 Google API 的问题。当我从不同的页面导航到 MapPage 时，MapPage 本身会显示地图 OK，但是当从 HomePage 移动到 MapPage 时，它只显示地图的一半。如果我手动刷新或调整地图大小，它会修复它 - 但我已经尝试过 map.resize() 没有运气，所以我需要一个不同的解决方案。
我在下面附上了我的 HomePage 和 MapPage 的 HTML 代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="description" content="Project - Mobile" />
<meta name="author" content="Yuval Vardi" />

我的 javascript 文件：

navigator.geolocation.getCurrentPosition(showPosition,showError);

function showPosition(position) {
