Hello,

I need help with js on prestashop 1.7.

I want to create a button in product page that updates the number of products selected.

For example:

If I press red button, quantity_wanted box change to 5:

How to do that?

I suppose I need to modify /theme/_dev/js/product.js

with something like that:

$(document).ready(function(){

$('.qty_five').on('click',function(){

$('#quantity_wanted').val(parseInt($('#quantity_wanted').val())+4);

});

The problem is JS doesn't work.

Any idea?

I need first steps to begin.

Thanks!
