【前端】JavaScript判断ua

判断设备是移动端还是PC

isMobile() {
  // Regular expression to match common mobile user agent strings
  var mobileRegex = /Mobi|Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i;
  return mobileRegex.test(navigator.userAgent);
}

判断系统是IOS还是Android

detectOS() {
  this.loading = true;
  var userAgent = navigator.userAgent || navigator.vendor || window.opera;

  // iOS
  if (/iPad|iPhone|iPod/.test(userAgent) && !window.MSStream) {
    this.device = "iOS";
  }
    // Android
  else if (userAgent.match(/Android/i)) {
    this.device = "Android";
  }
    // 如果不是上述两者，可能是PC或其他平台，可根据需要添加更多判断
  else {
    this.device = "Unknown";
  }
}
