Hi,

Code below works fine up to hr. For some reason, html code appears as is in textarea. It should first appear as notmal text. Anyone know why?

Thanks

<!DOCTYPE html>
<html>
<head>
  <style>
  p { margin:8px; font-size:20px; color:blue; 
      cursor:pointer; }
  b { text-decoration:underline; }
  button { cursor:pointer; }
  </style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
  <p>
    <b>Click</b> to change the <span id="tag">html</span>
  </p>
  <p>
    to a <span id="text">text</span> node.
  </p>
  <p>
    This <button name="nada">button</button> does nothing.
  </p>
  <br />

  <hr />

  <div>Now click me to turn plain text into html code in textarea below.</div>
  <br />
  <textarea rows="3" cols="20"><b>Bold</b></textarea>

<script>
    $("p").click(function () {
      var htmlStr = $(this).html();
      $(this).text(htmlStr);
    });

    $("div").click(function () {
      var htmlStr = $('textarea').html();
      $('textarea').text(htmlStr);
    });
</script>

</body>
</html>

You can not apply different formatting to different parts of the same textarea, i.e. you can not make some text bold and some text italic at the same time inside a textarea.

It does not identify html tags as html tags when you put in between textarea tags. So that is why you see <b>Bold</b> as it is.

I'm not trying to do that What I'm saying is a textarea shouln't show html tags.

If you have HTML tags between <textarea></textarea> tags, they will be treated as plaintext content in the textarea, not as HTML tags. The browser will not interpret them as HTML tags, but will basically convert the < to &lt; and > to &gt; and you will see the tags printed on the page as regular text.

When you open page above , what you see in textarea is this: <b>Bold</b>, not this: Bold neither somethimg else as you claim.

var htmlStr = $('textarea').text();
$('textarea').text(htmlStr.replace(/(<([^>]+)>)/ig,""));

Excellent my friend. Thank you very much
