Question

我有一张表格要求他们购买的小部件数量，最终目标是相应地改变paypal成本。如何调整代码以获得所需的结果？

    var amountOfWidgets = document.getElementById('firstBox').value;
    document.getElementById("price").innerHTML = "<input type="hidden" name="amount" value=amountOfWidgets>"
}

</script>
<div id="myCheckout">
</br>
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_xclick">
    <input type="hidden" name="business" value="Example@gmail.com">
    <input type="hidden" name="item_name" value="Donation">
    <input type="hidden" name="item_number" value="1">
    <input type="hidden" id="price" name="amount" value="6.99">
    <input type="hidden" name="no_shipping" value="0">

Answer 1

给表单命名。 PayPal通常将其命名为_xclick。

使用Javascript：

document._xclick.amount.value = price;

Answer 2

<input type="text" id="usd" size="20" name="usd" onchange="workaround()"

function workaround() {
var amount = document.getElementById("usd").value;
   paypal.Button.render({
      rest of paypal code...
      ...
      amount: { total: amount , currency: 'USD' }
      ...
   }
}

会做的伎俩...

Paypal API动态价格变动？
