如何在paymemscreen.js odoo14中替代功能validateOrderisForceValidate？

如何解决如何在paymemscreen.js odoo14中替代功能validateOrderisForceValidate？

我试图取代功能validateOrder（isForceValidate）...

var pos_model = require('point_of_sale.models');
const PaymentScreen = require('point_of_sale.PaymentScreen');

var models = pos_model.PosModel.prototype.models;

var rpc = require('web.rpc');


    class PosScreen extends PaymentScreen {



     constructor(isForceValidate) {
        super(isForceValidate);
        this.template = 'PaymentScreen';
  }

    async validateOrder(isForceValidate) {
//            var self = this;
            super.validateOrder(isForceValidate);
            console.log("validate==========================>")


        }


    }

但是单击“验证”按钮时控制台不起作用...如何替换此功能。
