Possible To Have Two Variables Upon One Select?

Can I have 2 variables upon one select? The code below is created dynamically with php from a database, and displays a dropdown select box, the only thing is that the values: Oliver Franchis, Pedro pastor, Maria China... have unique ID's and when the name is selected I would like the ID allso to be.

<!-- Populate list with friends START-->
var newTextbox = document.createElement('select');
newTextbox.className = 'fn-select';
newTextbox.name = "opcion";

//First user in the populated select menu is the person Loged in
var op1 = new Option("", "Oliver Franchis");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Me | Oliver Franchis');
op1.appendChild(txt1);

//Next users are my friends in the database
var op1 = new Option("", "Pedro pastor");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Pedro pastor');
op1.appendChild(txt1); .....
