I am using a library which has a bug for safari 5.1+ until 5.9 on iOS (mobile) but it work fine after 6.0 (6.0 included) on iOS.
The library in question does allow to remove the element that generates the bug:
Turbolinks.ProgressBar.disable();
How can I say to javascript to apply the function removeProgressBar only to safari <6.0 (strict inferiority) on iOS :
function removeProgressBar {
Turbolinks.ProgressBar.disable();
}
Important:
Safari 6.0 and safari 6.0+must not be affected on iOS nor on desktop (OS X) (I don't want to remove progress bar in this case)
safari 5.1.x on desktop (OS X) must not be affected (I don't want to remove progress bar in this case)
not sure if it matters but I am using bootstrap 3
Read this post: Browser detection in JavaScript?. It has some useful information on detecting browser and version. Be careful though, because this can never be 100% reliable.
