NOT Sure: Need help with code...

**muizyusuff** · 05-17-2011 06:59 PM

Hey, I am a beginner in JS and don't really understand it. I created this code for a text.

Code:

<script>
function post()
{
var re = document.GetElementById("text");
document.getElementById('submit').innerHTML="re";
if (re == "" || re == "null"){
alert("Type in a Text");
return false;
}
else {
return true;
}
}
</script>
<textarea id="text"></textarea>
<button id="post" onclick="post()">Post</button>
<blockquote id="submit"></blockquote>

I am trying to copy the text written in the textarea box into bhe blockquote section when you click "POST" button in the section below:

Code:

document.getElementById('submit').innerHTML="re";

I am also trying to place a false return when the textarea content has a null or no value in the code below:

Code:

if (re == "" || re == "null"){
alert("Type in a Text");
return false;
}
else {
return true;
}

I need Help with these. I probabally gor the HTML incorrect or JS...

Please and thank you.

You had several syntax errors...note changes.

Code:

<!DOC HTML>
<html>
<head>
<title> PostNote </title>
<script type="text/javascript">
function postNote() {
  var re = document.getElementById("text").value;
  document.getElementById('submit').innerHTML = re;
  if (re == "" || re == "null"){
    alert("Type in a Text");
    return false;
  } else {
    return true;
  }
}
</script>
</head>
<body>
<textarea id="text"></textarea><br>
<button id="postBtn" onclick="postNote()">Post</button>
<button onclick="document.getElementById('text').value = ''">Clear</button>
<blockquote id="submit"></blockquote>
</body>
</html>

Use the error console in FF to help debug.
