JS根据浏览器的useAgent来判断浏览器的类型
userAgent 属性是一个只读的字符串，声明了浏览器用于 HTTP 请求的用户代理头的值。
javascript语法：navigator.userAgent
PHP语法：$_SERVER['HTTP_USER_AGENT']
ASP语法：Request.ServerVariables("HTTP_USER_AGENT")
ASP.NET语法：HttpContext.Current.Request.UserAgent
JSP语法：request.getHeader("User-Agent")

接下来，如何判断浏览器的类型呢 ？
IE 浏览器 ：
| Token | Description |
|---|---|
| Edge | Windows Edge |
| Trident/7.0 | IE11 |
| Trident/6.0 | Internet Explorer 10 |
| Trident/5.0 | Internet Explorer 9 |
| Trident/4.0 | Internet Explorer 8 |
