  var bIsUc = sUserAgent.match(/ucweb/i) == 'ucweb'
  var bIsAndroid = sUserAgent.match(/android/i) == 'android'
  var bIsCE = sUserAgent.match(/windows ce/i) == 'windows ce'
  var bIsWM = sUserAgent.match(/windows mobile/i) == 'windows mobile'
  if (
    !(
      bIsIpad ||
      bIsIphoneOs ||
      bIsMidp ||
      bIsUc7 ||
      bIsUc ||
      bIsAndroid ||
      bIsCE ||
      bIsWM

// 更详细的探测当前客户端使用的操作系统
function detectOS() {
  var sUserAgent = navigator.userAgent
  var isWin = navigator.platform == 'Win32' || navigator.platform == 'Windows'
  var isMac =
    navigator.platform == 'Mac68K' ||
    navigator.platform == 'MacPPC' ||
    navigator.platform == 'Macintosh' ||
    navigator.platform == 'MacIntel'
  if (isMac) return 'Mac'
  var isUnix = navigator.platform == 'X11' && !isWin && !isMac
  if (isUnix) return 'Unix'
  var isLinux = String(navigator.platform).indexOf('Linux') > -1
  if (isLinux) return 'Linux'
  if (isWin) {
    var isWin2K =
      sUserAgent.indexOf('Windows NT 5.0') > -1 ||
      sUserAgent.indexOf('Windows 2000') > -1
    if (isWin2K) return 'Win2000'
    var isWinXP =
      sUserAgent.indexOf('Windows NT 5.1') > -1 ||
      sUserAgent.indexOf('Windows XP') > -1
    if (isWinXP) return 'WinXP'
    var isWin2003 =
      sUserAgent.indexOf('Windows NT 5.2') > -1 ||
      sUserAgent.indexOf('Windows 2003') > -1
    if (isWin2003) return 'Win2003'
    var isWin2003 =
      sUserAgent.indexOf('Windows NT 6.0') > -1 ||
      sUserAgent.indexOf('Windows Vista') > -1
    if (isWin2003) return 'WinVista'
    var isWin2003 =
      sUserAgent.indexOf('Windows NT 6.1') > -1 ||
      sUserAgent.indexOf('Windows 7') > -1
    if (isWin2003) return 'Win7'
  }
  return 'other'
}

另一种方法，使用 mootools 框架

var s = null
s = Browser.Platform.linux
alert(s)
if (Browser.Platform.linux) alert('linux')
else alert('not linux')

使用 JS 架框有现成的判断

例如 motools 架框中：

  • Browser.Platform.mac - (boolean) 当前操作系统是否为 Mac

  • Browser.Platform.win - (boolean) 当前操作系统是否为 Windows

  • Browser.Platform.linux - (boolean) 当前操作系统是否为 Linux

  • Browser.Platform.ipod - (boolean) 当前操作系统是否为 iPod Touch / iPhone

  • Browser.Platform.other - (boolean) 当前操作系统即不是 Mac, 也不是 Windows 或 Linux

  • Browser.Platform.name - (string) 当前操作系统的名称
