如何在iOS7的useragent字符串中区分Chrome和Safari？ [英] How does one differentiate between Chrome and Safari in an iOS7 useragent string?

问题描述

Useragent的细节很粗略，或者我没有在正确的地方寻找。根据 navigator.userAgent.match（）的内容，iOS7上的Chrome和Safari将有所不同，iPad还是iPhone？

解决方案

  var ua = navigator.userAgent; 
 var matches = ua.match（/^.*（iPhone | iPad）。*（OS \s [0-9]）。*（CriOS | Version）\ / [。0-9] * 。\sMobile * $ / I）; 
 if（！matches）console.log（不是我们想要的。）; 
 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）; 
}

Useragent details are sketchy, or I'm not looking in the right places.

What, in terms of a navigator.userAgent.match(), would differentiate between Chrome and Safari on iOS7, iPad or iPhone?

解决方案

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");
}
