我要做的是在用户点击“提交”后检索stripeToken，我所做的代码隐藏是

    <script>

        // Create a Stripe client
        var stripe = Stripe('pk_test_2O7D78OBubjUApxMMbvbHLVr');
        var test = "Whatsup";
        // Create an instance of Elements
        var elements = stripe.elements();

        // Custom styling can be passed to options when creating an Element.
        // (Note that this demo uses a wider set of styles than the guide below.)
        var style = {
            base: {
                color: '#32325d',
                lineHeight: '24px',
                fontFamily: '"Helvetica Neue", Helvetica, sans-serif',

            invalid: {

                iconColor: '#fa755a'
            }
        };

        // Create an instance of the card Element
        var card = elements.create('card', { style: style });

        // Add an instance of the card Element into the `card-element` <div>
        card.mount('#card-element');

        // Handle real-time validation errors from the card Element.
        card.addEventListener('change', function (event) {
            var displayError = document.getElementById('card-errors');
            if (event.error) {
                displayError.textContent = event.error.message;
            } else {
                displayError.textContent = '';
            }
        });

        // Handle form submission
        var form = document.getElementById('payment-form');
        form.addEventListener('submit', function (event) {
            event.preventDefault();

            stripe.createToken(card).then(function (result) {
                if (result.error) {
                    // Inform the user if there was an error
                    var errorElement = document.getElementById('card-errors');
                    errorElement.textContent = result.error.message;
                } else {
                    // Send the token to your server
                    stripeTokenHandler(result.token);
                }
            });
        });

        function stripeTokenHandler(token) {
            // Insert the token ID into the form so it gets submitted to the server
            var form = document.getElementById('payment-form');
            var hiddenInput = document.createElement('input');
            hiddenInput.setAttribute('type', 'hidden');
            hiddenInput.setAttribute('name', 'stripeToken');
            hiddenInput.setAttribute('value', token.id);
            form.appendChild(hiddenInput);

            // Submit the form
            form.submit();
        };


    </script>

    <script type="text/javascript">
        function abc() {
            var str = "value";
            document.getElementById("Hidden1").value = str;
        }
</body>
</html>

但我尝试调试以检查值，它似乎是“null”

如何从代码隐藏端检索它？

谢谢！

您的表单从未提交给服务器，这就是您获取null的原因。当您单击Button1时，它只会在服务器上触发Button1_Click（）事件。

您可以按F12，将调试器放在下面的功能上，看到它永远不会到达那里。

function stripeTokenHandler(token) {
        // Insert the token ID into the form so it gets submitted to the server
        var form = document.getElementById('payment-form');
        var hiddenInput = document.createElement('input');
        hiddenInput.setAttribute('type', 'hidden');
        hiddenInput.setAttribute('name', 'stripeToken');
        hiddenInput.setAttribute('value', token.id);
        form.appendChild(hiddenInput);

        // Submit the form
        form.submit();
    };

我的建议是：

配置表单，在提交时向控制器请求API。

要将表单onsubmit处理程序添加到以下块：

<script type="text/javascript">
function abc() {
    var str = "value";
    document.getElementById("Hidden1").value = str;
}

你可以试试上面那个让我知道结果吗？
