javascript - ExtJS Support for Browser Detection -

-

i want detect browser type can log browser type in case of error in extjs application. know there several javascript libraries can detect browser type, if deploy these code have update libraries regularly.

my question is: extjs job keeping browser detection functionality up-to-date? using extjs 4.2.

does extjs job keeping browser detection functionality up-to-date? using extjs 4.2.

it does. version 4.2 not quite up-to-date though. use latest ext js if crucial have browser detection functionality up-to-date.

in 4.2, ext singleton has range of properties telling browser. starting version 5 there dedicated ext.browser singleton.
