如何使用JavaScript将HTML转换为RTF

我有一个带有页眉和页脚的输入HTML文件.
需要将其转换为RTF. HTML的页眉/页脚应在生成的RTF文件中重复.

是否有任何插件可以仅使用JavaScript将HTML转换为RTF？

解决方法:

您可以使用this converter

但是,它没有解决要点(ul,li元素)

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;
}
