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 ：

 

TokenDescription
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


JS 代码:
