javascript - if else-works,if else with ternary operator doesn't work -


i have simple if/else statement,and works normally,but doesn't work when replace if/else statement using ternary operator.

  if (upordown == -1 ) {     sec_in_view++   } else{     sec_in_view--   }

that works,but how can make work using if/else statement ternary operator. tried this.

   (upordown == -1 ) ? sec_in_view++ : sec_in_view--

sorry acctually problem in previous line,which didn't had ";" on end,but line long , outside of view , tottaly forgot check that.

try assignment:

sec_in_view = (upordown == -1 ) ? sec_in_view+1 : sec_in_view-1;

or

sec_in_view = (upordown == -1 ) ? sec_in_view++ : sec_in_view--;
