如何动态将 html 元素插入 iframe

为了将 html 元素动态地插入 iframe 中，可以使用以下步骤：

创建 iframe 元素：使用标签创建新的 iframe 元素。</li><li><strong>获取 iframe 的 doc 元素：</strong>使用 iframe.contentdocument 或 iframe.contentwindow.document 来获取 iframe 的文本文档对象 (doc)。</li><li><strong>创建需要的 html 元素：</strong>使用 javascript 创建新的 html 元素，例如 <div> 或 <p>。</li><li><strong>将新元素插入 doc：</strong>使用 appendchild() 方法将新元素插入 iframe 的 doc 中。</li></ol><p>例如：</p><pre class="brush:php;toolbar:false">// 创建 iframe const iframe = document.createelement('iframe'); // 获取 iframe 的 doc const doc = iframe.contentdocument || iframe.contentwindow.document; // 创建一个新的段落元素 const paragraph = doc.createelement('p'); paragraph.innertext = '这是插入到 iframe 中的文本'; // 将段落元素插入 iframe 中 doc.body.appendchild(paragraph);</pre><p>此外，还有一些第三方库（例如 jquery）可以简化此过程，例如：</p><pre class="brush:php;toolbar:false">$('#iframe').contents().find('body').append('<p>这是插入到 iframe 中的文本</p>');</pre><p>好了，本文到此结束，带大家了解了《如何动态地将 HTML 元素插入 iframe？》，希望本文对你有所帮助！关注golang学习网公众号，给大家分享更多文章知识！</p>
