我是jsdom的新手，我只想在节点服务中使用draft js将html标记转换为json。我得到了用于转换的jsdom，所以我处理了它，所以正常的标签工作得很好，但有些标签不工作。这是我的密码。
const { JSDOM } = jsdom;
const { window } = new JSDOM();
const { document } = (new JSDOM(`<!DOCTYPE html>`)).window;
global.document = document;
global.navigator = window.navigator
global.HTMLElement = window.HTMLElement
const djs = require('draft-js')
const html = '<p>Hey this <span>editor</span> rocks 😀</p>';
const json=djs.convertToRaw(djs.ContentState.createFromBlockArray(djs.convertFromHTML(html)))
console.log("Hello",json);
var jQuery = require('jquery')(window);
它给我错误

有趣的事实代码在没有span标记的情况下工作。
const { JSDOM } = jsdom;
const { window } = new JSDOM();
const { document } = (new JSDOM(`<!DOCTYPE html>`)).window;
global.document = document;
global.navigator = window.navigator
global.HTMLElement = window.HTMLElement
const djs = require('draft-js')
const html = '<p>Hey this rocks 😀</p>';
const json=djs.convertToRaw(djs.ContentState.createFromBlockArray(djs.convertFromHTML(html)))
console.log("Hello",json);
var jQuery = require('jquery')(window);
我需要将html数据转换为json。
由于要将浏览器对象添加到节点的global，因此还需要添加Node对象，如下所示：
// [...]
global.HTMLElement = window.HTMLElement
global.Node = window.Node // <== Add this
// [...]
这是因为嵌套的<span>标记在<p>标记内创建文本节点，Draft.js正在解析这些节点。
我不知道你的代码的上下文，但如果你只想把一个HTML字符串转换成JSON/JS对象，那么使用xml2js这样的东西可能会更容易：
const util = require('util');
const parseString = util.promisify(require('xml2js').parseString); // `promisify` makes it possible to use `async/await`
(async function(){
const obj = await parseString('<p>Hey this <span>editor</span> rocks 😀</p>');
console.log(obj); // { p: { _: 'Hey this rocks 😀', span: [ 'editor' ] } }
}());
