Trying to write a user script to return a unique ID

Question

I am new to confluence and user macros.

I have managed to create a simple user script as follows -

## @noparams
$content.getIdAsString()

Which works fine and returns the page id.

However I want to extend the functionality here to only return the last x characters in the string.

How would I do this?

$content.getIdAsString().split()

#Velocity is just a façade for real Java objects, so you have access to all the public methods of the String class, including indexOf and substring.

I tried the below and it gave me what I wanted.

## @noparams
$content.getIdAsString().substring(4)

Hopefully this helps somebody else also.

Thanks to Danyal for the tip.
