我使用上面的代码从 MySQL 数据库获取谷歌地图位置。
以上代码从 MySQL 数据库中获取 lat、Lang 并动态创建 google map 。
当我运行上面的代码时，它给了我这样的错误:
有两个错误，名为太多递归和initMap不是函数。
谁能帮我解决一下吗？
提前致谢。
最佳答案
您尚未在 js 文件中定义 initMap。这就是您收到该错误的原因。您可能需要从 google map api 脚本中删除回调部分
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async defer></script>
至
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY" async defer></script>
还要检查以下语句中的纬度和经度是否包含有效的数值
var lat = new google.maps.LatLng(addressDetails[1], addressDetails[2]);
关于php - 谷歌地图中的递归太多，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38784829/
