Add text to a textarea

I read a post about this before and I followed a link that should have helped but I'm still getting errors.

How to add text to a textarea

Here is a simple test of the concepts I learned from that link:

Expand|Select|Wrap|Line Numbers

 <?xml version="1.0" encoding="iso-8859-1"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
 
<head>

   <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

   <title>Textarea Test</title>
 
   <script type = "text/javascript">

      <!--
 
      function addtext( txt ) {

         document.myform.mytextarea.value += txt;
 
      }
 
      addtext( "I like cheese." );
 
      // -->

   </script>

</head>
 
<body bgcolor="#ffffff">
 
   <form name = "myform" onSubmit = "return false;">
 
      <label>Textarea:</label><br />
 
      <textarea name = "mytextarea" rows = "20" cols = "50"></textarea>
 
   </form>
 
</body>

</html>

IE gives me an error that says "Line 15 Char 7 Error: document.myform.mytextarea is null or not an object. Code: 0"

Any ideas as to what I'm doing wrong?

I also visited this website...

http://www.hscripts.com/tutorials/javascript/dom/textarea-events.php

and tried this code...

Expand|Select|Wrap|Line Numbers

 <?xml version="1.0" encoding="iso-8859-1"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

   <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

   <title></title>
 
   <script type = "text/javascript">

      document.form1.textn.value = "testy";

   </script>
 
</head>
 
<body bgcolor="#ffffff">
 
   <form name=form1>

   <textarea name=textn> testing text area </textarea>

   </form>
 
</body>

</html>

_______________________________________________

According to the W3C HTML documentation the "value" attribute is not defined for the textarea control, try the innerHTML attribute, as in:
document.form1.textn.innerHTML = "testy";

It's simple ! You loading document with all elements. But you load it in sequence. And in this time it's not done. Object form is not loaded !

Try thist:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title></title>

<script type = "text/javascript">
function mojeFunkce()
{
document.form1.textn.value = "testy";
}
</script>

</head>

<body bgcolor="#ffffff" onload='mojeFunkce()'>

<form name=form1>
<textarea name=textn> testing text area </textarea>
</form>

</body>
</html>

and this:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title></title>

<script type = "text/javascript">

document.form1.textn.value = "testy"; // this will not works !!!

</script>

</head>

<body bgcolor="#ffffff" onload='mojeFunkce()'>

<form name=form1>
<textarea name=textn> testing text area </textarea>
</form>

</body>
</html>

Yes!, I didn't look further than the property for Textarea, missed the fact that it was being executed BEFORE the page was loaded!
