【问题描述】：
作为实验的一部分，我正在使用 Node-Red。我正在创建一个简单的工作流程，只需单击一个按钮，就可以将各种网站的（下载 html 内容）嵌入到它自己的页面上。
但是，提取的 HTML，msg.payload，将自动编码为 HTML。因此，我会得到&lt;div class=&quot;shot&quot;&gt;，而不是定期<div>。这会破坏这个想法。
使用“功能节点”，我可以将任何 Javascript 应用到 msg.payload，从而提取 HTML。我需要找到一种将 HTML 实体解码回良好 HTML 的方法。
msg.payload 默认情况下已包含提取的内容，因此如果需要，您可以在 Javascript 变量中使用它；
var x = msg.payload
那么 tl;dr：如何仅使用 Javascript 解码 HTML 实体？
如果您想“摆弄”我的工作流程，请复制并粘贴以下代码。
