Copy and Paste

These options control how content is handled when pasted or dropped into the editor, including format stripping, style retention, and preprocessing callbacks.

editor42.init({
  selector: 'textarea',
  paste_as_text: false,
  paste_data_images: true,
  smart_paste: true,
  paste_preprocess: (plugin, args) => {
    // Strip all bold tags from pasted content
    args.content = args.content.replace(/<\/?strong>/gi, '');
  },
  paste_postprocess: (plugin, args) => {
    // Add a class to all pasted paragraphs
    const paragraphs = args.node.querySelectorAll('p');
    paragraphs.forEach(p => p.classList.add('pasted'));
  }
});
