推荐答案

这是以下几种情况之一，浏览器版本检测似乎是有效的方法。为了最小化这种方法的危险，确保使用黑名单，而不是白名单，无论这可能如何不直观的感觉现在（以确保你不留下新的未来浏览器，发生了很多旧的netscape为重点的代码）。我知道这不是你想听到的答案，但因为 console.log 是一个本地函数，它的效果可以没有观察到，到目前为止因为我可以看到唯一的选择是做浏览器版本检测。

This is one of these few cases where browser version detection seems the valid way to go. To minimize the dangers of this approach make sure to use a blacklist rather than a whitelist, no matter how unintuitive this might feel right now (to make sure you don't leave out new future browser as happened with a lot of old netscape focused code). I am aware that this isn't the answer you wanted to hear, but as console.log is a native function and it's effect can in no way be observed, so as far as I can see the only option is to do browser version detection.
