mobile - How to determine which iPhone version the javascript code runs on?

Question

Need to distinguish between iPhone3x and iPhone4x. Is there any way to figure out the version from JavaScript please?

Answer 1

It would be a combination of two methods in Javascript:

function iPhoneVersion() {
  var iHeight = window.screen.height;
  var iWidth = window.screen.width;

  if (iWidth === 414 && iHeight === 896) {
    return "Xmax-Xr";
  }
  else if (iWidth === 375 && iHeight === 812) {
    return "X-Xs";
  }
  else if (iWidth === 320 && iHeight === 480) {
    return "4";
  }
  else if (iWidth === 375 && iHeight === 667) {
    return "6";
  }
  else if (iWidth === 414 && iHeight === 736) {
    return "6+";
  }
  else if (iWidth === 320 && iHeight === 568) {
    return "5";
  }
  else if (iHeight <= 480) {
    return "2-3";
  }
  return 'none';
}

function isIphone() {
  return !!navigator.userAgent.match(/iPhone/i);
}
