直接上代码，自己拿去测试
// 检测设备状态
const detectDeviceType = () =>/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent,)? 'Mobile': 'Desktop';const isMobile = detectDeviceType() === 'Mobile';
console.info(isMobile, '--true: 是移动端--')const isDesktop = detectDeviceType() === 'Desktop';
console.info(isDesktop, '--true: 是PC端--')
