javascript - 在表单 id html-editor-form 中显示 HTML 值

Question

我有四个部分。当我单击相应的图标时，每个部分都会显示。

visual-editor 部分有很多 html 值。

我想在 html-editor 部分中显示类 visual-editor 下的所有 html 值。

我有一个文本区域字段，我想将所有 html 元素作为值放在 visual-editor 类下。

Answer 1

使用 innerHTML 获取 .visual-editor 的 html 并将此内容分配给 textarea。

const visualEditor = document.querySelector('.visual-editor');

document.querySelector('.html-editor textarea').value = visualEditor.innerHTML;

<div class="editor-container">
  <div class="visual-editor">
