【问题描述】：
我正在开发一个具有嵌入式地图的网络应用程序，使用 LatLong 设置，但我无法将它呈现到我的 GSP 视图中。这是我的 GSP 代码：
<%@ page import="cr.consultingservices.DA.Avaluo" %>

如您所见，我什至没有删除 Google 示例纬度和经度，以检查我的坐标是否有错误。
我知道脚本没有放在视图的最佳位置，但我只是把它放在那里以便更好地理解。发生的事情是它只是变成空白，不显示错误或什么也没有。
我对Grails 和Javascript 有点陌生，因此我们将不胜感激任何帮助。提前致谢！

老实说，我还没有尝试过，所以一旦我尝试了，我会回复这个。我保证，我不会忘记

我想你忘了。

@CharlesMcKelvey 感谢您提醒我。我确实忘记了，但答案确实有效。现在接受。谢谢！
