在香草的 iframe src 中插入 window.location.href
insert window.location.href in iframe src in vanilla
我想弄清楚如何将当前页面 url 插入已加载但隐藏在同一页面上的 iframe src。我不想使用 jQuery 因为有其他功能。
如您所见,我正在尝试将其复制到 iframe 代码段中。
任何帮助将不胜感激,谢谢!

aux.setAttribute("value", document.getElementById(elementId).innerHTML);
document.body.appendChild(aux);
aux.select();
document.execCommand("copy");
document.body.removeChild(aux);
}
</script>

只需在 <script>
中分配 URL:
if(window.top == window.self) {
// otherwise you end up in infinite nested iframes
const iframe = document.getElementById('card');
iframe.src = window.location.href;
}
