Most of programming languages have substring or equivalent. I'm looking for a way to do this in Visualforce.
My requirement is adding a link to show a popup(show/hide div) to display a comment field which is some what lengthy. The content of the hyper link should be first 10 characters of the same comment field.

<a href="#" onclick="showNote('{!item.comment}');">{!item.comment}</a>

Possible Suggestion/Solution #1

This can be done with LEFT page variable function.

<a href="#" onclick="showNote('{!item.comment}');">{!LEFT(item.comment,10)}</a>   

There some other important page variable functions also out there in salesforce as described here.
