html 转 rtf How to convert HTML to RTF using JavaScript js html to rtf 有大用 有大大用 有大大大用

You can use this converter

However it does not address bullet points (ul, li elements)

function convertHtmlToRtf(html) {
  if (!(typeof html === "string" && html)) {
      return null;
  }

  var tmpRichText, hasHyperlinks;
  var richText = html;

  // Singleton tags
  richText = richText.replace(/<(?:hr)(?:\s+[^>]*)?\s*[\/]?>/ig, "{\\pard \\brdrb \\brdrs \\brdrw10 \\brsp20 \\par}\n{\\pard\\par}\n");
  richText = richText.replace(/<(?:br)(?:\s+[^>]*)?\s*[\/]?>/ig, "{\\pard\\par}\n");

  // Empty tags
  richText = richText.replace(/<(?:p|div|section|article)(?:\s+[^>]*)?\s*[\/]>/ig, "{\\pard\\par}\n");
  richText = richText.replace(/<(?:[^>]+)\/>/g, "");

  // Hyperlinks
  richText = richText.replace(
      /<a(?:\s+[^>]*)?(?:\s+href=(["'])(?:javascript:void\(0?\);?|#|return false;?|void\(0?\);?|)\1)(?:\s+[^>]*)?>/ig,
      "{{{\n");
  tmpRichText = richText;
  richText = richText.replace(
      /<a(?:\s+[^>]*)?(?:\s+href=(["'])(.+)\1)(?:\s+[^>]*)?>/ig,
      "{\\field{\\*\\fldinst{HYPERLINK\n \"$2\"\n}}{\\fldrslt{\\ul\\cf1\n");
  hasHyperlinks = richText !== tmpRichText;
  richText = richText.replace(/<a(?:\s+[^>]*)?>/ig, "{{{\n");
  richText = richText.replace(/<\/a(?:\s+[^>]*)?>/ig, "\n}}}");

  // Start tags
  richText = richText.replace(/<(?:b|strong)(?:\s+[^>]*)?>/ig, "{\\b\n");
  richText = richText.replace(/<(?:i|em)(?:\s+[^>]*)?>/ig, "{\\i\n");
  richText = richText.replace(/<(?:u|ins)(?:\s+[^>]*)?>/ig, "{\\ul\n");
  richText = richText.replace(/<(?:strike|del)(?:\s+[^>]*)?>/ig, "{\\strike\n");
  richText = richText.replace(/<sup(?:\s+[^>]*)?>/ig, "{\\super\n");
  richText = richText.replace(/<sub(?:\s+[^>]*)?>/ig, "{\\sub\n");
  richText = richText.replace(/<(?:p|div|section|article)(?:\s+[^>]*)?>/ig, "{\\pard\n");

  // End tags
  richText = richText.replace(/<\/(?:p|div|section|article)(?:\s+[^>]*)?>/ig, "\n\\par}\n");
  richText = richText.replace(/<\/(?:b|strong|i|em|u|ins|strike|del|sup|sub)(?:\s+[^>]*)?>/ig, "\n}");

  // Strip any other remaining HTML tags [but leave their contents]
  richText = richText.replace(/<(?:[^>]+)>/g, "");

  // Prefix and suffix the rich text with the necessary syntax
  richText =
      "{\\rtf1\\ansi\n" + (hasHyperlinks ? "{\\colortbl\n;\n\\red0\\green0\\blue255;\n}\n" : "") + richText +  "\n}";

  return richText;
}

After a bit of search I found a working solution:

https://www.npmjs.com/package/html-to-rtf

With html-to-rtf the conversion is easy (here's a piece of code based on browserify):

var htmlToRtf = require('html-to-rtf');
var htmlText = "<div>...</div>"; //or whatever html you want to transform
var htmlAsRtf = htmlToRtf.convertHtmlToRtf(htmlText); // html transformed to rtf

This solution worked for me. Without browserify you'll have to find implied js inside downloaded modules with npm and link them to your html page.

I applied @Samra solution and it was working good. But then I spotted a bug in the output: some text was cut off. After a lot of investigation, it seemed to be about HTML comments (<!-- xxxx -->) weren't being handled properly. My solution was to add this richText transformation as the first one:

// Delete HTML comments
richText = richText.replace(/<!--[\s\S]*?-->/ig,"");

According to Francisco Valles answer i created a bundle to easily include it your web-project:

正确答案   有大用 我亲自做的方法  见附件里面的中的 index.html 可以正常运行

https://github.com/geraphl/javascript-html-to-rtf-browser

<script src="~/js/html-to-rtf-browser.min.js"></script>

Then you can convert html to microsofts rtf format by adding

var htmlToRtfLocal = new window.htmlToRtf();
var rtfContent = htmlToRtfLocal.convertHtmlToRtf(htmlContent);

to you javascript.
