Question

我在我的项目上嵌入谷歌地图，但它无法正常工作。我为之前的项目使用了相同的代码，效果很好。当我检查控制台时，它显示错误＆＃34; TypeError：a为null＆＃34; 。

这是我的代码

<script>

  jQuery(function($) {
// Asynchronously Load the map API 
var script = document.createElement('script');
script.src = "http://maps.googleapis.com/maps/api/js?key=AIzaSyCcgSw6pOY1_1t4LpPQK360V0reIfLDOi0&callback=initialize"; 
document.body.appendChild(script);
});

任何帮助都将不胜感激。

Answer 1

您有一个“map_wrapper”HTML元素。但是在你的代码中你使用“map_canvas”。这些必须匹配。将一个改为另一个。

这有效，我没有太大改变。

我做了几行评论（比如我没有的图标），随意把它们放回去。

我还将你的四个“威斯敏斯特修道院”项目换成了与标记相匹配的东西
