When using Javascript to implement interaction between the client and the server, you sometimes need to judge the operating system to achieve compatibility under different operating systems. For example, we have a website, in Windows XP, the browsing effect is good, but in Ubuntu, due to many different features, it may cause slight differences in browsing, and ev

For windows systems, the version is not determined here. If necessary, you can continue to judge the version after determining windows. The java version needs to be considered. The version is different and the results are different.
