如何使用JavaScript找到操作系统名称和操作系统版本?


当前回答

使用DetectOS.js。这是一个简单的JS定义,适用于没有依赖关系的流行操作系统和浏览器:

class DetectOS { constructor() { this.browser = this.searchString(this.dataBrowser()) this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) this.OS = this.searchString(this.dataOS()) } searchString(data) { for (let i = 0; i < data.length; i++) { let dataString = data[i].string, dataProp = data[i].prop this.versionSearchString = data[i].versionSearch || data[i].identity if (dataString) { if (dataString.indexOf(data[i].subString) !== -1) { return data[i].identity } } else if (dataProp) { return data[i].identity } } } searchVersion(dataString) { let index = dataString.indexOf(this.versionSearchString) if (index === -1) return return parseFloat(dataString.substring(index+this.versionSearchString.length + 1)) } dataBrowser() { return [ /*************** * Chrome ***************/ { string: navigator.userAgent, subString: "Chrome", identity: "Chrome" }, /*************** * Safari ***************/ { string: navigator.vendor, subString: "Apple", identity: "Safari", versionSearch: "Version" }, /*************** * For Older Opera (12.18-) ***************/ { prop: window.opera, identity: "Opera", versionSearch: "Version" }, /*************** * Internet Explorer 10 ***************/ { string: navigator.userAgent, subString: "MSIE", identity: "IE10", versionSearch: "MSIE" }, /*************** * Internet Explorer 11 ***************/ { string: navigator.userAgent, subString: "Trident", identity: "IE11", versionSearch: "rv" }, /*************** * Edge ***************/ { string: navigator.userAgent, subString: "Edge", identity: "Edge", versionSearch: "Edge" }, /*************** * Firefox ***************/ { string: navigator.userAgent, subString: "Firefox", identity: "Firefox" }, { string: navigator.userAgent, subString: "Gecko", identity: "Mozilla", versionSearch: "rv" }, /*************** * For Older Netscapes (4-) ***************/ { string: navigator.userAgent, subString: "Mozilla", identity: "Netscape", versionSearch: "Mozilla" }, /*************** * For Newer Netscapes (6+) ***************/ { string: navigator.userAgent, subString: "Netscape", identity: "Netscape" }, /*************** * Other Browsers ***************/ { string: navigator.userAgent, subString: "OmniWeb", versionSearch: "OmniWeb/", identity: "OmniWeb" }, { string: navigator.vendor, subString: "iCab", identity: "iCab" }, { string: navigator.vendor, subString: "KDE", identity: "Konqueror" }, { string: navigator.vendor, subString: "Camino", identity: "Camino" } ] } dataOS() { return [ { string: navigator.platform, subString: 'Win', identity: 'Windows' }, { string: navigator.platform, subString: 'Mac', identity: 'macOS' }, { string: navigator.userAgent, subString: 'iPhone', identity: 'iOS' }, { string: navigator.userAgent, subString: 'iPad', identity: 'iOS' }, { string: navigator.userAgent, subString: 'iPod', identity: 'iOS' }, { string: navigator.userAgent, subString: 'Android', identity: 'Android' }, { string: navigator.platform, subString: 'Linux', identity: 'Linux' } ] } } const Detect = new DetectOS() console.log("We know your browser – it's " + Detect.browser + " " + Detect.version); console.log("We know your OS – it's " + Detect.OS); console.log("We know everything about you.");

var OSName = "Unknown";

我开始写一个脚本来读取操作系统和浏览器版本,可以在小提琴上测试。请随意使用和扩展。 断变化: 自2020年9月以来,新的Edge被检测到。所以“Microsoft Edge”是基于Chromium的新版本,旧Edge现在被检测为“Microsoft Legacy Edge”!

你可以使用这个javascript函数来检查用户的操作系统

  function getOS() {
  var userAgent = window.navigator.userAgent,
      platform = window.navigator.platform,
      macosPlatforms = ['Macintosh', 'MacIntel', 'MacPPC', 'Mac68K'],
      windowsPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE'],
      iosPlatforms = ['iPhone', 'iPad', 'iPod'],
      os = null;

  if (macosPlatforms.indexOf(platform) !== -1) {
    os = 'Mac OS';
  } else if (iosPlatforms.indexOf(platform) !== -1) {
    os = 'iOS';
  } else if (windowsPlatforms.indexOf(platform) !== -1) {
    os = 'Windows';
  } else if (/Android/.test(userAgent)) {
    os = 'Android';
  } else if (!os && /Linux/.test(platform)) {
    os = 'Linux';
  }

  return os;
}

alert(getOS());

https://developer.mozilla.org/en-US/docs/Web/API/NavigatorUAData/platform

console.log (navigator.userAgentData.platform)

例如:macOS, Windows

警告:window.navigator.platform已弃用
