Answer 1

its innerHTML not value, sorry.

res.innerHTML = res.innerHTML.substr(0, res.innerHTML.length-1);

Answer 2

Okay

Answer 3

Answer 5

Can you give me an example of the code your trying to explain?

Answer 6

Hmm, do you know how to make it so when you delete everything, it resets to 0 instead of nothing?

Answer 7

whats wrong with set it to "0" ? it should work

Answer 8

maybe
str.substr(str.length-1);

there may be another way to do it, but thats what i can think of

Answer 9

in your case its need to be res.value
not just res
