编程学习 2021-07-04 21:48www.dzhlxh.cn编程入门
关于我们使用电脑的操作系统，我们通过鼠标点击就能获取，如果我们想用脚本怎么实现javascript获取本机操作系统类型的方法呢，狼蚁网站SEO优化给大家分享javascript获取本机操作系统类型的方法，需要的朋友可以参考下
废话不多说了，狼蚁网站SEO优化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

fOperaVersion = parseFloat(RegExp["$1"]);
}

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。
