推荐答案
您打算这一切的错误的方式。你不支持浏览器，支持的功能。浏览器不会过期像豆子会在你的厨房一个即可。开发时使用的功能检测和polyfills - 这将追溯提供给浏览器10岁的支持
You're going about it all the wrong way. You don't support browsers, you support features. Browsers don't expire like a can of beans would in your pantry. Use feature detection and polyfills when developing - this will retroactively provide support to browsers 10 years old.
各种工具存在，以帮助可能缺乏的功能部门，你支持的浏览器。一种流行的一种是Modernizr的。这不仅暴露出的对象，告诉你40关于用户代理能够不同的东西，它也polyfills HTML5标记的一个子集，并附加信息CSS类名到您的文档，让你的风格对浏览器的支持或不要'T支持任何给定功能。
Various tools exist to help you support browsers that may be lacking in the feature department. One popular one is Modernizr. Not only does this expose an object that tells you over 40 different things about what the user agent is capable of, it also polyfills a subset of HTML5 tags, and attaches informative CSS classnames to your document that let you style against browsers that support or don't support any given feature.
使用大的做法是这样最终会导致您的客户提供更好的体验，改进了对你的雇主声誉，少沮丧你不必试图找出一些神奇的前pression确定一个露脸的古风一些可变的用户代理字符串的浏览器。
Using great practices like this will ultimately result in a better experience for your clients, improved reputation for your employer, and less frustration for you having to try and figure out some magical expression for determining the antiquity of a faceless browser by some mutable user agent string.
