高德地图开发javascript出现错误

调用高德地图开发时出现不明问题，找不到源头，请各位帮帮忙，说一下调试这种问题的思路

以下是报错的信息

Uncaught TypeError: Cannot read property 'Out' of undefined

at c.Yg.transition (eval at Cl (eval at (maps?v=1.3&key=235ee41…:17)), :1:2891)

at c.update (eval at Cl (eval at (maps?v=1.3&key=235ee41…:17)), :1:381)

at eval (eval at (maps?v=1.3&key=235ee41…:17), :48:73)

Yg.transition @ VM368:1

update @ VM365:1

(anonymous) @ VM363:48

thanks :)

我好像知道了一个问题，应该需要加入dom监听，然后调用方法，我去试试，嘿嘿(●´∀｀●)
