HTML清除格式常用方法有哪些

function stripHtml(html) {
  let temp = document.createElement('div');
  temp.innerHTML = html;
  return temp.textContent || temp.innerText || '';
}

function cleanHtml(html) {
  // 移除 style, class, 属性
  html = html.replace(/<[^>]*?(style|class|align|face)[^>]*>/gi, '');
  // 清理空标签
  html = html.replace(/<([^>]+)>\s*<\/\1>/g, '');
  return html;
}

const editor = document.getElementById('editor');
const plainText = editor.textContent; // 完全无格式文本

const cleanText = editor.innerHTML
  .replace(/
/gi, '\n')
  .replace(/
(.*)<\/p>/gi, '$1\n')
  .replace(/<[^>]+>/g, '');

import DOMPurify from 'dompurify';

const clean = DOMPurify.sanitize(dirty, {
  ALLOWED_TAGS: ['p', 'br', 'strong', 'em'],
  ALLOWED_ATTR: [] // 不允许任何属性，清除style/class等
});

$clean = strip_tags($html, '

');
