Script to calculate amount of digits in a given number. - Willing to pay for this.

[Seb Meikle]

Hi,
I am not very experienced in JavaScript, so I need some help here. I've had a look around the net but I can't seem to find this.

I am looking for a simple script that will calculate the amount of digits in a given number entered in a text box and output the value into a different text box or preferably a hidden value.

For example:

1 would be 1 digit.
01 would be 2 digits.
10 would be 2 digits
100 would be three digits.

And so on.

I need this so I can calculate the cost of a door number. Numerals cost £2.00 each so I need the form I am building to calculate the cost of a door number. I need this to be a script that calculates on the fly without going to a separate page.

This is quite important so I would be willing to pay a small fee if someone could write this for me, I will pay via PayPal. I am 100% serious no BS as I need this ASAP.

How much are you willing to pay for four lines of code? ;-)

var myDestinationBox = document.getElementById('IDofdestinationbox');
var myDigitBox = document.getElementById('IDofdigittextbox');
var valueOfDigits = parseInt(myDigitBox.value, 10);
if(!NaN(valueOfDigits)) myDestinationBox.value = myDigitBox.value.length;

Haha, I said I didn't know JavaScript. I also didn't' search very well as I found what I needed as soon as I had posted this.

Thank you for your input.

Sorry to be a pain.
