方法二：引用插件mobile-detect.js，可以获取
- console.log( md.mobile() ); // 'Sony'
- console.log( md.phone() ); // 'Sony'
- console.log( md.tablet() ); // null
- console.log( md.userAgent() ); // 'Safari'
- console.log( md.os() ); // 'AndroidOS'
- console.log( md.is('iPhone') ); // false
- console.log( md.is('bot') ); // false
- console.log( md.version('Webkit') ); // 534.3
- console.log( md.versionStr('Build') ); // '4.1.A.0.562'
- console.log( md.match('playstation|xbox') ); // false
