javascript使函数参数动态化

dil*_*ert 5 html javascript

因此,我试图在我的order.html页面上包括付款API结帐,但是,您必须在HTML文档的开头添加脚本。在脚本中,您必须将小计金额指定为数字,但是我需要此值是动态的。“总计”是小计金额。我需要将小计设为“总计”。我该怎么做?

<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 subtotal 即可从 html 中获取值,如下所示

<script type="text/javascript">
function paymentApi(){
    V.init( {
    apikey: "",
    encryptionKey: "",
    paymentRequest:{
        currencyCode: "USD",
        subtotal: document.getElementById('stotal').innerText //Here
    }
    });
</script>
