How to include html tags in text editor? [Snippet attached]

问题

I am making text editor using, react-draft-wysiwyg and draftjs-to-html ..

And also I have injected the dynamic html into editor like,

index.js:

export default function App() {
  const dynamicData = `<div class="heading"> This text needs to display along with the <span> html tags </span> surrounded </div>`;

  const handleInputChange = (e) => {
    console.log("event ", e.target.value);
  };

  return (
    <>
      <ContentEditor
        name="dynamicContent"
        value={dynamicData}
        onChange={(event) => handleInputChange(event)}
      />
    </>
  );
}

Current Working scenario:

Here the things are working very well and I am able to get the plain text like,

This text needs to display along with the html tags surrounded

inside the editor.

Note: (I mean to say only text is displayed without the html tags like div, span..

Expected:

I am in the need to bind the entire HTML as it is inside the editor like,

<div class="heading"> This text needs to display along with the <span> html tags </span> surrounded </div>

Working Snippet:

So my requirement is that need to display the text inside editor as,

<div class="heading"> This text needs to display along with the <span> html tags </span> surrounded </div>

instead of

This text needs to display along with the html tags surrounded

As already stated by @Rod911 you can do something like this:

import "../carousel.css";
import React from "react";
import ContentEditor from "../components/text_editor";

function escape(unescaped) {
  return unescaped
    .replace(/&/g, "&")
    .replace(/</g, "&lt;")
    .replace(/>/g, "&gt;")
    .replace(/"/g, "&quot;")
    .replace(/'/g, "&#039;");
}

function unescape(escaped) {
  return escaped
    .replace(/&amp;/g, "&")
    .replace(/&lt;/g, "<")
    .replace(/&gt;/g, ">")
    .replace(/&quot;/g, '"')
    .replace(/&#039;/g, "'");
}

export default function App() {
  const dynamicData = escape(
    `<div class="heading">This text needs to display along with the <span> html tags </span> surrounded </div>`
  );

  const handleInputChange = (e) => {
    console.log("event ", unescape(e.target.value));
  };

  return (
    <>
      <ContentEditor
        name="dynamicContent"
        value={dynamicData}
        onChange={(event) => handleInputChange(event)}
      />
    </>
  );
}

May be it would be nice to use a specific Class for the content, which would simplify the convertion. May be take a look at: https://www.itsrainingmani.dev/blog/string-prototype-extension/

Try this:

export default function App() {

    function getConvertedText(text) {
        console.log(text);
        text = text.replace(/</g, "&lt;").replace(/>/g, "&gt;");
        return text;
    }
    const dynamicData = '<div class="heading"> This text needs to display along with the ' + getConvertedText("<span> html tags </span>") + ' surrounded </div>';

    const handleInputChange = (e) => {
        console.log("event ", e.target.value);
    };

    return ( <
        >
        <
        ContentEditor name = "dynamicContent"
        value = {
            dynamicData
        }
        onChange = {
            (event) => handleInputChange(event)
        }
        /> <
        />
    );
}
