谷歌地图API：使用javascript和html接受相同半径的搜索地址
我想要实现的是在内部接受相同半径的客户端地址，如果该地址不具有相同半径，则应进行验证（“地址未接受”），否则该地址将不起作用谷歌地图API：使用javascript和html接受相同半径的搜索地址,javascript,jquery,html,css,google-maps,Javascript,Jquery,Html,Css,Google Maps,我想要实现的是在内部接受相同半径的客户端地址，如果该地址不具有相同半径，则应进行验证（“地址未接受”），否则该地址将不起作用 当客户或用户在radius内输入相同地址的地址时，应进行验证（“接受”） 当客户或用户输入的地址与radius内的地址不一致时，应进行验证（“不接受”） 下面是我尝试执行的代码：- <html> <title></title> <head></head> <script src="https://ajax
