Question

我有一个我无法工作的脚本。我一直收到错误'Geocoder failed'但我不确定为什么。它应该得到long / lat然后反向地理编码它以在警告框中显示街道地址。我已经尝试确保浏览器让它共享该位置。我也尝试过通过HTTPS访问，因为我读到现在需要它，但它仍然无效。如果有人能帮助我完成这项工作，我将非常感激！提前谢谢。

Answer 1

您的errorFunction会自动传递error参数，您可以查看该参数：

function errorFunction(error){
    alert("Geocoder failed: "+error.message);
}
