javascript使函数参数动态化

所以我试图在我的 order.html 页面上包含支付 API 结帐，但是，您必须在 HTML 文档的头部添加一个脚本。在脚本中，您必须将小计金额指定为数字，但我需要该值是动态的。“总计”是小计金额。我需要将小计设置为“总计”。我怎么做？


<head>

  <script type="text/javascript">

    function paymentApi() {

      V.init({

        apikey: "",

        encryptionKey: "",

        paymentRequest: {

          currencyCode: "USD",

          subtotal: "11.00"

        }

      });

  </script>

</head>


<body>

  <p id="sub-total">

    <strong>Total</strong>: <span id="stotal"></span>

  </p>

只需更改小计即可从 html 中获取值，如下所示<script type="text/javascript">function paymentApi(){&nbsp; &nbsp; V.init( {&nbsp; &nbsp; apikey: "",&nbsp; &nbsp; encryptionKey: "",&nbsp; &nbsp; paymentRequest:{&nbsp; &nbsp; &nbsp; &nbsp; currencyCode: "USD",&nbsp; &nbsp; &nbsp; &nbsp; subtotal: document.getElementById('stotal').innerText //Here&nbsp; &nbsp; }&nbsp; &nbsp; });</script>

<script type="text/javascript">function paymentApi(){&nbsp; &nbsp; var subtotal = parseFloat($("#stotal").text());&nbsp; &nbsp; V.init( {&nbsp; &nbsp; apikey: "",&nbsp; &nbsp; encryptionKey: "",&nbsp; &nbsp; paymentRequest:{&nbsp; &nbsp; &nbsp; &nbsp; currencyCode: "USD",&nbsp; &nbsp; &nbsp; &nbsp; subtotal: subtotal&nbsp; &nbsp; }&nbsp; &nbsp; });</script>
