I am using Odoo 12 and have the need to write a JavaScript function on Odoo point of sale, that allows me to make a list of all taxes included on the pos order lines.

I need to show, tax name and tax description for every pos order line (cannot show duplicate taxes).

For instance (pos order lines):

• Product 1: Tax A;
• Product 2: Tax B;
• Product 3: Tax A + B;
• Product 4: Tax A;

In this example, I have 4 product lines and used 2 taxes (A and B).

The list of taxes should only show one line for each tax.

For instance:

INCLUDED TAXES:

-Tax A name: Tax A description

-Tax B name: Tax B description

Can anyone help me write this JS function? I lack of JS knowledge to do it myself.

I know how to add it to receipt and just need the JavaScript function.

Thank you all in advance

Best regards

PM
