I hesitate to say this (as I don't believe the answer will help you much in the long run), but you can use the Trident token of the user-agent string to determine the version of IE that's actually running. 我犹豫地说（因为从长远来看，我不认为答案会为您带来很大帮助），但是您可以使用用户代理字符串的Trident令牌来确定实际运行的IE版本。

This is a dangerous practice , one that will likely get more complex as time goes on. 这是一种危险的做法，随着时间的流逝，这种做法可能会变得更加复杂。

Perhaps a better question is to ask why you need to distinguish between versions? 也许更好的问题是问您为什么需要区分版本？ For troubleshooting purposes, you can use the F12 tools to investigate individual cases. 为了进行故障排除，您可以使用F12工具调查个别情况。

You didn't indicate what sort of behavioral differences you're seeing between the two machines. 您没有指出两台计算机之间的行为差异。 As a result, it's hard to recommend more appropriate alternatives. 结果，很难推荐更合适的替代方案。 You may find the IE Compatibility Cookbook helpful, as it outlines some of the major changes in recent versions of IE (as well as a few of the minor ones ). 您可能会发现《 IE兼容性手册》很有用，因为它概述了IE的最新版本中的一些主要更改（以及一些次要的更改）。
