How to Get custom fields on the confirmation page in the Elbrus version

We can extend the confirmation in submit function of LiveOrder.Model. So we need to override the module of LiveOrder.Model.

We are adding the example of the override of the module

ns.package.json

{
    "gulp": {
        "javascript": [
            "JavaScript/*.js"
        ],
        "ssp-libraries": [
            "SuiteScript/*.js"
        ]
    },
    "overrides": {
        "suitecommerce/LiveOrder@4.0.0/JavaScript/LiveOrder.Line.Model.js" : "JavaScript/LiveOrder.Line.Model.js",
        "suitecommerce/LiveOrder@4.0.0/SuiteScript/LiveOrder.Model.js" : "SuiteScript/LiveOrder.Model.js"
    }
}

So with the help of the extension, we can extend the LiveOrder.Model and we can submit the customize the customize function.

  , submit: function submit() {

                var confirmation
                    , payment = ModelsInit.order.getPayment();

                var customFields = JSON.stringify(this.getTransactionBodyField())
                var customFields1 = JSON.stringify(ModelsInit.order.getCustomFieldValues())
                var tempcard_stripe = _.findWhere(JSON.parse(customFields1), { name: 'custbody_jj_tempcard_stripe' });

                if (!threedsecure && payment && payment.paymentterms === 'CreditCard' && SC.Configuration.isThreeDSecureEnabled) {
                    return this.process3DSecure();
                }
                else {
                    var paypal_address = _.find(ModelsInit.customer.getAddressBook(), function (address) {
                        return !address.phone && address.isvalid === 'T';
                    })
                        , confirmation = ModelsInit.order.submit();
                    // We need remove the paypal's address because after order submit the address is invalid for the next time.
                    this.removePaypalAddress(paypal_address);

                    ModelsInit.context.setSessionObject('paypal_complete', 'F');

                    if (this.isMultiShippingEnabled) {
                        ModelsInit.order.setEnableItemLineShipping(false); // By default non order should be MST
                    }

                    //As the commerce API does not remove the purchase number after submitting the order we manually remove it
                    this.setPurchaseNumber();
