如何在不影響使用 Nodejs 或 Javascript 的 HTML 標簽的情況下從 HTML 中獲取 100 到 200 個單詞？

Question

我從我的數據庫中獲取數據並通過郵件發送，數據帶有 HTML 標簽。 現在的問題是我只想在郵件中顯示 100 個字母。 但是當我刪除一些單詞時，HTML 標簽也會刪除，它會破壞整個輸出。 請指導我如何實現這一目標。

我使用類似'Hiya how are you'.substring(0,8);

你的貓使用cheerio libary作為它的：

const cheerio = require('cheerio');

const input = `

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

console.log(result.html());
