Uncaught InvalidValueError：initMap不是函数

问题描述 投票：4回答：3

我正在尝试加载带有一些特定参数的谷歌地图。我理解问题很可能是initMap函数需要全局声明。但是，即使在搜索了一些类似问题的StackOverflow帖子后，我也不知道如何。

我复制了你的代码但是有一些语法错误。所以我无法测试。但你的错误是关于initMap（当然:)）。删除所有代码并检查initMap和window.initMap。

function initMap() {alert("ok");}

谷歌回调有效吗？

发现它......虽然派对很晚......

如果您从此链接https://maps.googleapis.com/maps/api/js下载了google maps js代码，然后尝试使用它进行调用

<script async defer
  src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>

开发工具中存在代码被修改的错误。

在下载的文件中找到initMap并用""替换整个文件或者用以上链接的新副本替换然后锁定文件或将其标记为ReadOnly以避免将来出现同样的情况。

不是最好的方法，但它解决了我的问题。

如果回调函数不起作用，则手动调用initMap（）函数作为后备。

jQuery(document).ready(function($) {
    initMap();
});

希望这可以帮助。
