279758 - javascript: textarea_x.value.length counts 'enter' as a single character, but submit is done with \r\n (2 characters)

Status: RESOLVED DUPLICATE of bug 188015

(Core :: DOM: Core & HTML, defect)

Description

[Remke]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

If I understand correctly, a textarea should submit line endings as CR LF.
According to the W3C HTML 3.2 recommendation:
(the bit on textareas)
--clip--
   It is recommended that user agents canonicalize line endings to CR, LF
   (ASCII decimal 13, 10) when submitting the field's contents.
--clip--
Firefox DOES indeed submit 'enters' in a textarea as CR+LF, but javascripts
counts an 'enter' as a single character.
When trying to create a textarea with a maxlength, the text is trimmed to the
wrong length. 'Wrong' meaning 'different from server-side length'.

Reproducible: Always

Steps to Reproduce:
1. create a html form with the following javascript:
<SCRIPT LANGUAGE="JavaScript">
<!--
var maxlimit = 2;

function textCounter(fxield, countfxield) 
{
	if (fxield.value.length > maxlimit)
		fxield.value = fxield.value.substring(0, maxlimit);
	else
		countfxield.value = maxlimit - fxield.value.length;
}
//-->
</SCRIPT>
and a form with a textarea and a input type="text" field to display the count
Call the textCounter function in the onKeyDown/onKeyUp event handlers of your
textarea.
2. open the html form in your browser
3. type 'enter' twice in the textarea
4. now the textbox shows '2' (without the quotes of course)
5. if you submit the form (assuming you have some kind of server side scripting
environment) and inspect the length of the submitted textarea value, it will be
'4' (CRLFCRLF)

Actual Results:  
See in 'steps to reproduce'

Expected Results:  
I expected the client-side character count to be '4', because this is the length
of the actual string submitted.
