<p>在 Vue 3 中实现 iframe 高度自适应可以通过以下步骤进行:</p> <ol> <li>在你的组件中,使用 ref 创建一个对 iframe 元素的引用,例如: ```javascript<template> <div> <iframe ref="myIframe" src="https://example.com"></iframe> </div> </template></li> </ol> <script> import { ref, onMounted } from 'vue'; export default { setup() { const iframeRef = ref(null); onMounted(() => { // 在组件挂载后执行以下操作 adjustIframeHeight(); }); const adjustIframeHeight = () => { const iframe = iframeRef.value; if (iframe) { iframe.style.height = iframe.contentWindow.document.body.scrollHeight + 'px'; } }; return { iframeRef, adjustIframeHeight, }; }, }; </script> <p>```</p> <ol start="2"> <li>在 <code>adjustIframeHeight</code> 方法中,通过 <code>iframe.contentWindow.document.body.scrollHeight</code> 来获取 iframe 内部文档的高度,并将其设置为 iframe 的高度。</li> </ol> <p>注意:由于浏览器的同源策略限制,如果 iframe 的 src 地址与你的应用不在同一个域名下,上述方法可能无法获取到正确的高度。在这种情况下,你需要与 iframe 的内容页面进行通信,让其将自身的高度传递给父页面(即 Vue 应用)来调整 iframe 的高度。</p> <p>希望这个回答对你有帮助!如有任何问题,请随时提问。</p>
