JavaScript code showing html page in textarea

I want the html page written in textarea to display in html form
I know there are tools like htmledit. I can't use as many functions as it can. I just need to simply display it.

If you only want to display, you can use ()
If you still need to edit, I think you may still use tools such as htmledit. I am now studying fckeditor. It has several types and fewer functions. Hehe, my personal opinion, I hope it will be useful to you.

<textarea   id=tx1></textarea>   
  <input   type=button   value="show"   onclick="test();")>   
  <script>   
  function   test()   
  {   
  x=("about:blank");   
  ();   
  }   
  </script>

Display in multi-line text box
  function   Deal(fString)   
    fString   =   replace(fString,   "&gt;",   ">")   
    fString   =   replace(fString,   "&lt;",   "<")   
    fString   =   Replace(fString,"&nbsp;",chr(32))   
    fString   =   Replace(fString,"&quot;",chr(34))   
    fString   =   Replace(fString,"&#39;",chr(39))   
    fString   =   Replace(fString,   "",   CHR(13))   
    fString   =   Replace(fString,   "</P><P>",   CHR(10)   &   CHR(10))   
    fString   =   Replace(fString,   "<BR>",   CHR(10))   
    Deal   =   fString   
  end   function   
This function can be used
