[SOLVED] Length NULL value error

Question

I am trying to get the length of a str.match in a div section.
Works fine👍
Except the NULL value😒.
When There isn't a match in the div, the length property throws me an error and can't output a value. (line 30 to 36)

How to change the NULL value(default) so it will outputs 0 as default and not an error😉.

Any help and/or explanation will be appericiated!

Answer 1

if(rollednums[0]==null) {
rollednums[0] = 0;
} else {
rollednums[0] = count.match(/1/g).length;
}

try it with all affected variables
maybe a for loop is a better choice 😉

Answer 3

mx lst,

It fixed the NULL issue, thanks.

But same issue appears when the dice rolled for example 4 times and no number six was rolled, then it will give me the same error..

See changes to code line 60 to 71
