Grabbing a custom attribute from a checkbox element

have a page with lotsa checkboxes, am using javascript to count the number of boxes checked and to total the prices for all boxes checked. would like to pass the "description" of each checkbox but cant get the code to trap this field.

here's what the checkbox looks like ...

we're using name, id, price in our calculations. how can I trap descrip and use to populate an order field?

Changed thread title to better describe the problem.

Heya, TX.

Have a look at Element::getAttribute().
