我如何禁用条纹付款中的付款请求按钮，直到选中了运输单选按钮

Question

我有一个结帐页面，当用户检查收音机并稍后单击“付款请求”按钮时，我在“收音机”按钮中具有运输选项，因此希望默认情况下将“付款请求”按钮保持为禁用状态。

我正在使用Stripe付款网关并正在使用Codeigniter

var paymentRequest = stripe.paymentRequest({
country: 'GB',
currency: 'gbp',
total: {
            label: 'total',
            amount: grand_total*100,
          },requestPayerName: true,
          requestPayerEmail: true,
        });
        var points=$("#point1").val();
        var elements = stripe.elements();
        var prButton = elements.create('paymentRequestButton', {
          paymentRequest: paymentRequest,
        });

paymentRequest.canMakePayment().then(function(result) {

  if (result) {
    prButton.mount('#payment-request-button');
  } else {
    document.getElementById('payment-request-button').style.display = 'none';
  }
});

$.post('<?php echo base_url();?>frontend/payment_methods/stripe_method/google_payment/google_pay')
          .done(function(session) {
          var result=session;
// console.log(result);
          var sess=JSON.parse(result);


          var clientSecret=sess.client_secret;
//alert(clientSecret);

paymentRequest.on('paymentmethod', function(ev) {
      //console.log(ev);exit();
  stripe.confirmPaymentIntent(clientSecret, {
    payment_method: ev.paymentMethod.id,

  }).then(function(confirmResult) {
    console.log(confirmResult.error);
    if (confirmResult.error) {

          ev.complete('fail');
    } else {


      ev.complete('success');
      stripe.handleCardPayment(clientSecret).then(function(result) {
        if (result.error) {
              window.location = '<?php echo base_url('frontend/payment_methods/stripe_method/google_payment/google_pay_fail');?>';
        } else {
              window.location = '<?php echo base_url('frontend/payment_methods/stripe_method/google_payment/index');?>';

        }
      });
    }
  });
});

});
