JavaScript gets native operating system type methods _javascript tips

Needless to say, the following is a code example to introduce, I hope to be able to bring more or less to help friends.

Sample code:

function Getosinfo () {var _pf=navigator.platform; 
 var appver=navigator.useragent; 
  if (_pf== "Win32" | | | _pf = = "Windows") {if (appVer.indexOf ("WOW64") >-1) {_bit = "64-bit"; 
  else {_bit = "32 bits"; } if (appVer.indexOf ("Windows NT 6.0") >-1 | | | appver.indexof ("Windows Vista") >-1) {if (_bit== ' 64-bit ' | | | ap 
   Pver.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-bit ') || 
   appVer.indexOf ("Windows 7") >-1) {return ' windows_7 ' +_bit; 
   else {return "unknow"; 
    } else {try {var _winname = Array ('% ', ' XP ', ' 2003 '); 
    var _ntnum = Appver.match (/windows NT 5.\d/i). toString (); Return ' Windows_ ' + _winname[_ntnum.replace (/windows NT 5. ( 
   \d)/I, "$"]+ "" +_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"; } 
}

The above code is very simple to achieve the JavaScript access to the native operating system types of methods, in a sample code to introduce JavaScript to obtain operating system version information

JavaScript gets the operating system version information

Sample code:

var suseragent = navigator.useragent;
var fappversion = parsefloat (navigator.appversion);
  Compare browser version size 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;
}//Detect if Opera browser var isopera = Suseragent.indexof ("opera") >-1;

  Foperaversion = parsefloat (regexp["$");
  } ISMINOPERA4 = Foperaversion >= 4;

The code is simple to get the operating system version information of the native or non-native, and hopefully it will be a little more or less helpful to everyone.
