I'm trying to fill a text area with new lines. But when I add a new line  CRLF (HTML line terminator for multi-line elements) using DOM, the new line is CR ended.

Then if I post this data to an action, it sends a single line value.

Reproducible: Always

Steps to Reproduce:
1.Save the following code as a html page.
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Insert title here</title>
<form  id="form-textarea" method="post" action="">
<textarea id="area" name="area"></textarea>
<input type="button" onclick="enviar()" value="Enviar" />
<script type="text/javascript">
    function enviar() {
        document.getElementById("area").value="hola\u000d\u000aadios" ;


2. Press button "Enviar"

Actual Results:  
Alert with  hola%0Aadios

Expected Results:  
Alert with  hola%0D%0Aadios

Sorry I said CR ended when it's LF ended

Newlines in the DOM are always LF only.  So the behavior is correct.

Thanks a lot.

It's strange you can send the CRLF in a form with a textarea, but you can't assign it by DOM to a textarea and send it. I'll take it into account.
If you put an LF in a textarea it should become a CRLF when the form is submitted, if you're on Windows.

Last comment, I didn't mention that  I'm using and XMLhttprequest to send data. 
In the application we found the problem we copied data from one textarea to another, and finally we sent the form with ajax.

I believed then it was a problem with textarea. Now I see we have to manage this situations before sending the request. 

My apologies and thanks again.
