When you look at the IE11 Windows 8 the newest came back sequence was ” Mozilla/5.0 (Window NT 6.3; Trident/eight.0; rv:eleven.0) such as Gecko “. This will be not the same as previous versions into after the popular indicates:

  • New appropriate (“compatible”) and you may internet browser (“MSIE”) words had been got rid of, definition you can don’t just come across “MSIE” from the userAgent to sniff aside Web browser in the IE11 otherwise above browsers.
  • The latest sort of the fresh internet browser is now claimed because of the a different sort of update (“rv”) key phrase.

You could potentially probe the latest userAgent assets to possess cellular internet explorer such new iphone, ipad, otherwise Android. Another changeable productivity genuine whether your affiliate is utilizing one to of your own pursuing the cellular browsers:

Without delay

At a glance at more than dining table, you may be influenced into turning to the following a few characteristics accomplish your internet browser recognition putting in a bid:

Into the internet explorer for example various types out of Netscape and you may Firefox, these two properties go back just “Netscape” for appName , and you can 5.0 to have appVersion without the after that improvement having Firefox as well as variation, and hence are very far useless on real world. Such as for example, in Firefox 5.x and you may Firefox thirty-five, those two features return:

We should instead look to a property that is alot more thorough inside its investigative functions if we need significantly more surface and reliability, and this happens to be navigator.userAgent .

Discovering Firefox x.x

This new detail we’re looking for seem to lays on extremely stop, or Firefox/thirty-five.0 like.

The newest region we have been wanting takes place following the string ” Firefox/ “, or the accurate type amount. There are many different the way to get to help you they using either simple String or RegExp measures- I’m going for the afterwards right here:

Keep in mind that certain variants off old Ie items together with incorporate “Trident” with its userAgent sequence, therefore do not count merely on “Trident” alone to separate your lives IE11+ about remainder of the herd- it’s just the presence of Both “Trident’ and you will a beneficial “rv” token one uniquely implies it is a IE11 or significantly more than web browser.
