React Js如何检测当前操作系统

function getOperatingSystem() {
  const userAgent = navigator.userAgent;
  let os = "Unknown";

  if (userAgent.indexOf("Win") !== -1) {
    os = "Windows";
  } else if (userAgent.indexOf("Mac") !== -1) {
    os = "MacOS";
  } else if (userAgent.indexOf("Linux") !== -1) {
    os = "Linux";
  } else if (userAgent.indexOf("Android") !== -1) {
    os = "Android";
  } else if (userAgent.indexOf("iPhone") !== -1 || userAgent.indexOf("iPad") !== -1) {
    os = "iOS";
  }

  return os;
}

console.log("Current OS:", getOperatingSystem());

// 使用 ua-parser-js 库
import UAParser from 'ua-parser-js';

const parser = new UAParser();
const result = parser.getResult();
console.log("Current OS:", result.os.name);
