Could you explain why this:
<script type="text/javascript">
document.write("<textarea cols='10' rows='10'>" + "\nhello\nbabe\n" + "</textarea>");
</script>
renders a textarea with one new line at the bottom, but NO new line at the top?
Tested IE8, FF11, Safari 5.1, Chrome 24
And it's not a JS issue, even when you write HTML in page you get the same result, i.e.
<textarea cols='10' rows='10'>
hello
babe
</textarea>
The 1st new line is still missing!!!
I need to add another new line at the top in order to show one:
document.write("<textarea cols='10' rows='10'>" + "\n\nhello\nbabe\n" + "</textarea>");

To add line breaks to a textarea, use the addition (+) operator and add the \r\n string at the place where you want to add a line break, e.g. 'line one' + '\r\n' + 'line two' . The combination of the \r and \n characters is used as a newline character. Here is the HTML for the examples in this article. Copied!
The text area tag defines a multi-line text input control. The size of a text area can be specified by the cols and rows attributes. By default, whenever we press “enter” or “shift+enter” it creates a new line in the text area.
If you want your text to overflow the parent's boundaries, you should use pre as your CSS whitespace property. Using white-space: pre wraps still preserves newlines and spaces. Enjoy!
Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n will work.
When writing inside of XHTML use proper entities.
<textarea> hello</textarea>
If a text node begins with white space (space, new line) it will be ignored by HTML parsers. Encoding the new line into a proper HTML entity forces the parser to acknowledge it.
