废话不多说了，下面通过一段代码示例介绍一下，希望能够给需要的朋友带来或多或少的帮助。
示例代码：
function getosinfo(){ var _pf=navigator.platform; var appver=navigator.useragent; if(_pf==win32 || _pf == windows) { if(appver.indexof(wow64)>-1) { _bit = 64位; } else { _bit = 32位; } if(appver.indexof(windows nt 6.0) > -1 || appver.indexof(windows vista) > -1) { if(_bit=='64位' || appver.indexof(windows vista) > -1) { return 'windows_vista '+_bit; } else { return unknow1; } } else if(appver.indexof(windows nt 6.1) > -1 || appver.indexof(windows 7) > -1) { if(_bit=='32位' || appver.indexof(windows 7) > -1) { return 'windows_7 '+_bit; } else { return unknow; } } else { try { var _winname = array('2000','xp','2003'); var _ntnum = appver.match(/windows nt 5.\d/i).tostring(); return 'windows_' + _winname[_ntnum.replace(/windows nt 5.(\d)/i,$1)]+ +_bit; } catch(e) { return 'windows'; } } } else if(_pf == mac68k || _pf == macppc || _pf == macintosh) { return mac; } else if(_pf == x11) { return unix; } else if(string(_pf).indexof(linux) > -1) { return linux; } else { return unknow; } }
以上代码很简单的实现了javascript获取本机操作系统类型的方法，一下在通过一段示例代码介绍javascript获取操作系统版本信息
javascript获取操作系统版本信息

无论是获取本机还是非本机的操作系统版本信息，代码都很简单，希望对大家获多或少的有点帮助。
