javascript获取本机操作系统类型的方法

时间：2021-09-01 08:59:55|栏目：JavaScript代码|点击： 次

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

示例代码：

var sUserAgent = navigator.userAgent;
var fAppVersion = parseFloat(navigator.appVersion);
//比较浏览器版本大小
function compareVersions(sVersion1,sVersion2){
  var aVersion1 = sVersion1.split(".");
  var aVersion2 = sVersion2.split(".");
  if(aVersion1.length>aVersion2.length){
    for(var i=0;i<aVersion1.length;i++)
      aVersion2.push("0");
  }else if(aVersion1.length<aVersion2.length){
    for(var i=0;i<aVersion2.length;i++)
      aVersion1.push("0");
  }
  for(var i=0;i<aVersion1.length;i++){
    if(aVersion1[i]<aVersion2[i])
      return -1;
    else if(aVersion1[i]>aVersion2[i])
      return 1;
  }
  return 0;
}
//检测是否Opera浏览器
var isOpera = sUserAgent.indexOf("Opera")>-1;
var isMinOpera4 = isMinOpera5 = isMinOpera6 = isMinOpera7 = isMinOpera7_5 = false;
if(isOpera){
  var fOperaVersion;

  } else {
    var reOperaVersion = new RegExp("Opera (http://www.cnblogs.com/eoiioe/admin/file://d+///d+)");
    reOperaVersion.test(sUserAgent);
