javascript获取本机操作系统类型的方法
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：
functionGetOSInfo()
{
var_pf=navigator.platform;
varappVer=navigator.userAgent;
if(_pf=="Win32"||_pf=="Windows")
{
if(appVer.indexOf("WOW64")>-1)
{
_bit="64位";
}
else
{
_bit="32位";
}
if(appVer.indexOf("WindowsNT6.0")>-1||appVer.indexOf("WindowsVista")>-1)
{
if(_bit=='64位'||appVer.indexOf("WindowsVista")>-1)
{
return'Windows_vista'+_bit;
}
else
{
return"Unknow1";
}
}
elseif(appVer.indexOf("WindowsNT6.1")>-1||appVer.indexOf("Windows7")>-1)
{
if(_bit=='32位'||appVer.indexOf("Windows7")>-1)
{
return'Windows_7'+_bit;
}
else
{
return"Unknow";
}
}
else
{
try
{
var_winName=Array('2000','XP','2003');
var_ntNum=appVer.match(/WindowsNT5.\d/i).toString();
return'Windows_'+_winName[_ntNum.replace(/WindowsNT5.(\d)/i,"$1")]+""+_bit;
}
catch(e)
{
return'Windows';
}
}
}
elseif(_pf=="Mac68K"||_pf=="MacPPC"||_pf=="Macintosh")
{
return"Mac";
}
elseif(_pf=="X11")
{
return"Unix";
}
elseif(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：
varsUserAgent=navigator.userAgent;
varfAppVersion=parseFloat(navigator.appVersion);
//比较浏览器版本大小
functioncompareVersions(sVersion1,sVersion2){
varaVersion1=sVersion1.split(".");
varaVersion2=sVersion2.split(".");
if(aVersion1.length>aVersion2.length){
for(vari=0;i<aVersion1.length;i++)
aVersion2.push("0");
}elseif(aVersion1.length<aVersion2.length){
for(vari=0;i<aVersion2.length;i++)
aVersion1.push("0");
}
for(vari=0;i<aVersion1.length;i++){
if(aVersion1[i]<aVersion2[i])
return-1;
elseif(aVersion1[i]>aVersion2[i])
return1;
}
return0;
}

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。
