用户代理字符串检测呈现引擎、平台、Windows操作系统、移动设备和游戏系统 js
前言
五大呈现引擎：
IE , Gecko , WebKit , KHTML , Opera .
- IE8,IE9呈现引擎:Trident;
- Firefox呈现引擎:Gecko,从Netscape6开始；
- safari呈现引擎:WebKit,safari从2003年出现；
（WebKit是Linux中Konqueror的呈现引擎KHTML的一个分支，之后独立成一个开源项目） - Konqueror呈现引擎:KHTML;
- Chrome呈现引擎:WebKit;
- Opera呈现引擎:Opera;
- ios和Android默认浏览器呈现引擎:WebKit。
以下是完整的用户代理字符串检测脚本，包括检测呈现引擎、平台、Windows操作系统、移动设备和游戏系统。
