With reference to the answers available under following question - What character represents a new line in a text area
The newline character in a textarea should be CRLF though entering data in a textarea with newline generates only \n as can be seen in the snippet below -
<textarea id="one" onchange="document.getElementById('contentdiv').innerText=JSON.stringify(document.getElementById('one').value)"></textarea>
<button onclick="document.getElementById('contentdiv').innerText=JSON.stringify(document.getElementById('one').value)">Read Content</button>
<div id="contentdiv"></div>
Are there references/changes in the defined standards for the textarea with respect to the changed behavior seen here?
