如何区分iOS7 useragent字符串中的Chrome和Safari？

Question

有用的细节是粗略的,或者我没有找到正确的地方.

就a而言,什么navigator.userAgent.match()可以区分iOS7,iPad或iPhone上的Chrome和Safari？

Answer 1

var ua = navigator.userAgent;
var matches = ua.match(/^.*(iPhone|iPad).*(OS\s[0-9]).*(CriOS|Version)\/[.0-9]*\sMobile.*$/i);
if (!matches) console.log("Not what we're looking for.");
else {
  console.log(matches[1]);
  if (matches[2] === 'OS 7') console.log(matches[2]);
  else console.log('Not the right version.');
  if (matches[3] === 'CriOS') console.log("Chrome");
  else console.log("Safari");
}
