如何在不影响使用 Nodejs 或 Javascript 的 HTML 标签的情况下从 HTML 中获取 100 到 200 个单词？

Question

我从我的数据库中获取数据并通过邮件发送，数据带有 HTML 标签。 现在的问题是我只想在邮件中显示 100 个字母。 但是当我删除一些单词时，HTML 标签也会删除，它会破坏整个输出。 请指导我如何实现这一目标。

来自数据库的示例输出

我使用类似'Hiya how are you'.substring(0,8);

你的猫使用cheerio libary作为它的：

const cheerio = require('cheerio');

const input = `

const result = cheerio.load(input.substring(0, 200), { xmlMode: true });

console.log(result.html());
