Hi all,

I want to customize POS receipt to run console.log() script when I click on Print Receipt button, but I don't know the way to implement it.

I try to edit renderElement() function but error

Here is my script, please help me. When I enter pos receipt screen, I have Failed module message. Thank in advance

odoo.define('pos_receipt_extend', function (require) {
    "use strict";
    var $ = require('jquery');
    // Add cost field to product model
    var models = require('point_of_sale.models');
    models.load_fields('product.product', 'standard_price');

    var screens = require('point_of_sale.screens');
    var render = screens.ReceiptScreenWidget.prototype.renderElement;
    var new_render = function () {
        render.apply(self);
        console.log('OK!');
    };
    screens.ReceiptScreenWidget.prototype.renderElement = new_render();
});
