Dynamically generate form from a joint table in Javascript

Hi!,

I'm trying to create a form that would be populated by a joint table and add more information to the destination table.
I have a Equipment_Rooms table which stores each Location,room and equipment as an Item that I want to be displayed in the form.


I need the JS to loop trough the above table to generate a checklist for each record that is related to a selected location to store it in the destination table Checks




Ex.

Location : BB 905

Living Room 
        Item                Evaluation                          Notes
