1、判断是否是ios端

     
export function isAndroid () {
  const u = window.navigator.userAgent
  const isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1
  if (isAndroid) {
    return true
  } else {
    return false
  }
}
    

2、判断是否是安卓端

    
export function isIos () {
  const u = window.navigator.userAgent
  const isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/)
  if (isiOS) {
    return true
  } else {
    return false
  }
}
