Windows Phone（7.5 和 8.0） 9 | 2. 火狐浏览器在安卓手机端的支持 10 | 3. IE11的支持 11 | 4. Opera浏览器在Opera 15之后放弃自家的浏览内核Prestro引擎，奔向了WebKit之后的一点识别问题 12 | 5. 添加了对win8 和win8.1的支持 13 | 14 | -------------------------------------------------------------------------------- /index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | User-agent Detection Example 5 | 6 | 7 | 8 | 9 |
