Question

so I’m wanting to do something like this:

I’ve got a variable that will return anything upto a 7 didget number, and i need to test the value of each digit individually.
I can only think to do it as a string, but please feel free to offer help as a string or an integer.

total = "1658793";
parseFloat(total.substring(6)) == 3;

returns “true”

but I need to be able to get the next value, and the next, and then next, individually.

and obviously

parseFloat(total.substring(5)) == 9;

returns “false”

as “parseFloat(total.substring(5)) = 93” but i need to be able to regex check or something to find the 9 on its own. i need the 9, not the 93
does that make sense??

thanks
Matt.

Answer 1

Just parse the entire starting number into an integer and examine its digits using the modulus (%) operator.

var num = parseInt(total, 10);
var ones = num % 10;
if (ones != 3) { ... }
num = (num - ones) / 10;
var tens = num % 10;
if (tens != 9) { ... }
num = (num - tens) / 10;
var hundreds = num % 10;

…And so on.
