各浏览器的用户代理字符串整理

每个浏览器都有它自己的用户代理（user agent）字符串，里面包含了浏览器和操作系统等信息。通过使用这个字符串，我们可以处理跨浏览器的差异。用户代理字符串保存在 JavaScript 的 navigator.userAgent 变量中。我们先来看看各个主流浏览器在各个平台的用户代理字符串的例子。

#### 1. IE 和 IE Mobile 浏览器 ####

#### 2. Firefox 和 Firefox Mobile 浏览器 ####

#### 3. Opera 和 Opera Mobile 浏览器 ####

在 Opera 12 及之前，使用的是 Presto 渲染引擎，它的 UA 字符串为：

而从 Opera 14 开始，它改用 Chrome 的 WebKit/Blink 渲染引擎，UA 字符串改变为：

#### 4. Chrome 和 Chrome Mobile 浏览器 ####

注意 Chrome for iOS 声称它是 CriOS。这是由于它只能使用 iOS 的 UIWebView 提供的网页渲染和脚本解释引擎，和 Chrome for Android 差别很大，而更加像 Safari for iOS。

#### 5. Safari 和 Safari Mobile 浏览器 ####

这里的 Safari for Android 指的是 Android 自带的浏览器；从用户代理字符串看，不论 Android 的版本，它都声称是 Safari Mobile 4.0。实际上它和 Chrome 一样也是从 Chromium 中移植出来的。

这里顺便整理并记录各版本 iOS 系统自带的 Safari Mobile 浏览器的版本，如下：

#### 6. 国内的各个浏览器 ####

国内也有好几个基于 WebKit 内核的浏览器（IE 内核的这里不讨论），它们的 user agent 字符串如下面的例子：

可以看到大部分浏览器都兼容 Safari 或 Chrome 的 UA 字符串。但是还是有很多胡乱使用的地方。比如 UC 浏览器比较古怪（在 UC 8.2 for Android 2.3 中测试）：在 user agent 中竟然不包含自己的版本号。

#### 7. navigator.platform ####

如果需要检测用户使用的操作系统，除了 navigator.userAgent 之外也可以用 navigator.platform。例如：
