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(){ V.init( { apikey: "", encryptionKey: "", paymentRequest:{ currencyCode: "USD", subtotal: document.getElementById('stotal').innerText //Here } });</script> -

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