dinesh9396 commented 1 month ago

does special characters includes numbers too. (in that case we cant enter numbers in title Example: "Top 10 A.I. courses to learn in 2024").

Plz explain me about this whole issue

We need to add a validation which will allow just Markdown as input

npm install markdown-it

import React, { useState } from 'react'; import MarkdownIt from 'markdown-it';

const md = new MarkdownIt();

const MarkdownValidator = () => { const [input, setInput] = useState(''); const [isValid, setIsValid] = useState(true); const [error, setError] = useState('');

const handleChange = (e) => { const value = e.target.value; setInput(value);

try {
  // Attempt to parse the input as Markdown
  md.parse(value);
  setIsValid(true);
  setError('');
} catch (err) {
  // If parsing fails, update the state to reflect invalid input
  setIsValid(false);
  setError(err.message);
}

};

return (

{isValid ? (
        <p style={{ color: 'green' }}>Valid Markdown</p>
      ) : (
        <p style={{ color: 'red' }}>Invalid Markdown: {error}</p>
      )}
    </div>
<p>);
};</p>
<p>export default MarkdownValidator;</p>
<p>Sample idea </p>
<p>We need to add this validation this will prevent us from user entering those kind of html scripts</p>            </div>
        </div>
    
    <div class="page-bar-simple">
            </div>

<div class="footer">
        <ul class="body">
            <li>© <script>
                    document.write(new Date().getFullYear())
                </script> Githubissues.</li>
            <li>Githubissues is a development platform for aggregating issues.</li>
        </ul>
    </div>

</html>
