Identify what it was selected with Checkbox

In my screen, I am displaying an HTML page with 3 check boxes and I have a button called "Process"

each of these three checkboxes represent a different material number

how can I take the values of these check boxes when user makes the selection

and click the button?

what i have so far is I have a javascript funtion that once the selection is made (checkboxes)

and user click the button I can find out what checkbox was selected but this in javascript so how can I related these with ABAP, my abap internal table?

thanks
