大佬，抖店的好像版本不一样。

bdms版本： https://lf-c-flwb.bytetos.com/obj/rc-client-security/web/stable/1.0.1.6-alpha.08/bdms.js

补环境半天，执行结果是个死循环，不知道哪里出问题。希望指点一下

[ShilongLee]

是不是_u是导出的函数呢，看不到你的上下文，你可以参考一下我之前的补环境代码。

source.js 只导出了window.qg函数，位置如下

死循环是不是有什么事件监听导致的，可以进循环看一下，执行的什么代码。或者把代理吐出的环境到日志里查看还有没有什么没补的，如果都补了，再看看是否是由于dom环境没补导致的，我的环境里没有补dom以及一些渲染函数，你可以尝试补一下。
