获取userAgent

const ua = navigator.userAgent.toLowerCase();

判断是否安卓

const isAndroid = () => {
  return ua.indexOf('android') > -1 || ua.indexOf('adr') > -1
}

判断安卓版本号

const getAndroidVer = () => {
  return ua.match(/android (.*?);/)
}

判断是否IOS

const isIos = () => {
  return !!ua.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/i)
}

  return ua.match(/cpu iphone os (.*?) like mac os/)
}
