- 如果您需要支持包括IE8在内的各种浏览器， Opera 12、Safari 5等都使用jQuery Compat 3.0.0包。 我们建议大多数网站使用此版本，因为它提供 为所有网站访问者提供最佳兼容性
- 如果您的网站仅为主流浏览器构建，或 webview中是否包含基于HTML的应用程序（例如PhoneGap或 Cordova）如果您知道正在使用哪些浏览器引擎，请选择 jquery3.0.0包
- 除非我们另行声明，否则两个包将包含相同的内容 相应编号的主要和次要版本中的公共API。这 应该使开发人员能够轻松地在两者之间切换，并且 最大限度地与第三方jQuery插件兼容。
参考：ASP.NET 4.0用户注意：jQuery 3.x中断回发。这个答案真的准确吗？据我所知，jQuery Compat 3.0的版本甚至不超过alpha版本。@HischT引用随答案一起提供。你所说的部分甚至是从jQuery自己的博客文章中抄袭过来的。我不知道你希望它有多准确，但我可以保证它不会比有来源作为参考更好。另外，看看这个答案的日期。那是两年多以前的事了。我尽我最大的努力让这篇文章与新发布的相关信息保持更新，但基本上就是这样。如果您觉得可以改进，请编辑答案，并让我或社区对其进行审查。@icecub请注意，我的评论是作为一个问题而不是一个真实的事实，因为我不是100%确定。我只是试着下载甚至找到了关于jQueryCompat3的任何信息，但除了你提到的那篇博文和它的另一个alpha版本之外，我找不到更多的信息。在我看来，他们似乎在发布前抛弃了jQuery Compat 3。如果有人能证明我错了，我会非常高兴，因为我很想在我的项目中使用jQuery Compat 3。在微软放弃对IE8-10的支持后，jQuery-Compat在2016年初发布之前被取消。
