javascript - jQuery which to detect empty space -


i trying figure out when key press empty space, did following:

 if (e.which == ' '){   }

however not work. idea why?

event.which returns code of character pressed. space key code 32, use instead:

if (e.which === 32) {     // }

another way convert character char code .charcodeat():

if (e.which === " ".charcodeat(0)) {     // }
