javascript - Increment variable based on global variable -


what want following code

$floorno = 1; // current floor  if ($floorno == 1){   $number1++; } else if ($floorno == 2){   $number2++; } ...

etc.

is there shorter version, ($number+$floorno)++; ?

you use array:

var arr = [1, 2, 3]; var floorno = 1; arr[floorno]++; // = [1, 3, 3]

if floorno entered user, can use modulo operator ensure it's valid:

arr[floorno % arr.length]++; // = [1, 3, 3]
