JavaScript HTML 转Markdown
掘金安东尼 人气:0前言:
本篇带来:在 JavaScript 如何将 HTML 转成 Markdown?先收藏,总有一天要用到!!
npm
我们主要是借助 Turndown 这个库来实现的
npm 安装
npm i turndown
es6 import 引入:
import TurndownService from 'turndown'
CommonJs require 引入:
const TurndownService = require('turndown');
接下来我们就可以简单的使用它了:
import TurndownService from 'turndown'; const html = ` <h1>Learn Web Development</h1> <p>Check out <a href="https://codingbeautydev.com/blog" rel="external nofollow" rel="external nofollow" >Coding Beauty</a> for some great tutorials!</p> `; // Create an instance of the Turndown service const turndownService = new TurndownService(); const markdown = turndownService.turndown(html); console.log(markdown);
输出如下:
Learn Web Development

script
除了 npm 安装的方式,我们还可以通过 <script>
标签引入的方式实现调用:
<script src="https://unpkg.com/turndown/dist/turndown.js"></script>
调用实现转换:和上面例子一致
const html = ` <h1>Learn Web Development</h1> <p>Check out <a href="https://codingbeautydev.com/blog" rel="external nofollow" rel="external nofollow" >Coding Beauty</a> for some great tutorials!</p> `; // Create an instance of the Turndown service const turndownService = new TurndownService(); const markdown = turndownService.turndown(html); console.log(markdown);
我们还可以直接对 dom 节点进行转换
// convert document <body> to Markdown const bodyMarkdown = turndownService.turndown(document.body);
参数配置
于此同时,turndown 还有一些参数可以配置:
比如 bulletListMarker
属性,可以将 markdown 中的 list 用符号作标记:
import TurndownService from 'turndown'; const html = ` <ul> <li>HTML</li> <li>CSS</li> <li>JavaScript<li>`; // Specifying options when creating an instance of the // Turndown service const turndownService = new TurndownService({ bulletListMarker: '-' }); const markdown = turndownService.turndown(html); console.log(markdown);
输出:
- HTML
- CSS
- JavaScript
