Javascript PayPal按钮在使用客户端REST api的Laravel中不显示

我已将PayPal支付选项添加到我的网站。我已将PayPal支付代码整合如下：

<div class="col-md-6 col-xs-12">
 <script src="https://www.paypalobjects.com/api/checkout.js"></script>
                        <div class="sec_pay_hd">
                            Payment Method
                        </div>
                        <div id="paypal-button-container"></div>
                        <div id="confirm" class="hidden">
                                    <div>Ship to:</div>
                                    <div><span id="recipient"></span>, <span id="line1"></span>, <span id="city"></span></div>
                                    <div><span id="state"></span>, <span id="zip"></span>, <span id="country"></span></div>

                                    <button id="confirmButton">Complete Payment</button>
                                </div>
                                <div id="thanks" class="hidden">
                                            Thanks, <span id="thanksname"></span>!
                                        </div>
                        <!-- <div class="pay_mode_img1 visa_imgsasa"> -->
                        <!-- </div> -->
                        <script>
                                    paypal.Button.render({

                                                var shipping = data.payer.payer_info.shipping_address;

                                                document.querySelector('#line1').innerText     = shipping.line1;

                                                document.querySelector('#confirmButton').addEventListener('click', function() {

                                                    // Disable the button and show a loading message

                                                    document.querySelector('#confirm').innerText = 'Loading...';

                        <div class="visa_imgsasa">
                            <img src="{{asset('assets/resources/images/visa-image.png')}}" alt="">
                        </div>

我在页面顶部添加了paypal脚本。但现在我不断地犯这个错误

非常感谢您的帮助，我已经在网上搜索了这个错误，但是没有找到任何错误。这是paypal网站演示的示例代码。但这在我的本地服务器上也不起作用。

$'navmenu'.mmenu

^从页面中删除此选项可修复此问题。我猜是从DOM中删除iframe，然后重新添加它，这会导致iframe的内部窗口关闭。

我很乐意帮助调试我维护的checkout.js-是否有一个实时页面可以重设此错误？删除了包含站点链接的注释_/_非常感谢，现在工作顺利。mmenu是第三方脚本，用于管理移动菜单和向右滑动。不知何故，这是干扰贝宝代码，我正在努力解决这个问题。但这是一种解脱。非常感谢你！！
