Javascript regex for product-key format

[vipzeus]

Hi everybody,
finaly after a long time i'm back to work

I have a field where user must put some code and with follow javascript code i have the keystring to uppercase on keyup event.

this.update( this.getValue().toUpperCase() );

I need to have the dashes for each 5 chars like
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Where XXXXX is alphanumeric like microsoft licence code.

Hey!

Try ...

this.update( this.getValue().toUpperCase().replace(/(\d{5})(\d{5})(\d{5})(\d{5})(\d{5})/, "$1-$2-$3-$4-$5"));

-- hugh

You might want to put in a test for the length before that. But that should convert something which is definitely 25 digits long, with no spaces or other characters.

-- hugh

Hi Hugh! Its nice to hear you again
Your code works for numbers only as you wrote above.
I change the code as:

this.update( this.getValue().toUpperCase().replace(/([a-zA-Z0-9]{5})([a-zA-Z0-9]{5})([a-zA-Z0-9]{5})([a-zA-Z0-9]{5})([a-zA-Z0-9]{5})/, "$1-$2-$3-$4-$5"));

and work as i need.
The dashes are added only if all 25 chars fill the field.
Is there way to get dashes after 5 chars during digit and without have compltely all 25 chars?

You can use the "Input mask" (field "Formatting")

Doh! Why didn't I think of that. I implemented that feature exactly for this kind of use.
