In all versions of IE (I'm testing IE11 at the moment) new line breaks inside of textarea elements aren't working...

function id_(id)
{ 
 var r = false;
 if (document.getElementById(id))
 {
  r = document.getElementById(id);
 }
 return r;
}

window.onload = function()
{
 for (i in document.getElementsByTagName('audio')[0])
 {
  id_('test').value = id_('test').value + '\n' +i;
 }
}

How can I force IE to break lines in a textarea element? No frameworks.

I've tried \n\r, \r\n, \r and \n.

• 2 jsfiddle/ff5kqtru this seems to work in IE11. What are u trying to achieve by that loop? – Comfortably Numb Commented Sep 22, 2014 at 17:21
• Try this $('#test').val($('#test').value + '\n' +i); ref:stackoverflow./questions/5583040/… – Sainath Motlakunta Commented Sep 22, 2014 at 17:24
• for (i in document.getElementsByTagName('audio')[0]) seems weird, are you sure it isn't for (i in document.getElementsByTagName('audio'))? – Igor Jerosimić Commented Sep 22, 2014 at 17:28
• 1 @IgorJerosimić, I assume he's iterating through the properties of the first audio tag, hence the [0]. – Rick Hitchcock Commented Sep 22, 2014 at 17:39

Sorted by: Reset to default 5

After minimizing the code the issue was the CSS white-space property which I fixed with the code below.

* {white-space: nowrap;}
textarea {white-space: pre;}

In IE, \n does indeed generate line breaks in textarea elements. That is, this code:

<textarea id="target">default text here</textarea>
<script>document.getElementById('target').value = 'a\nb';</script>

does, in IE, result in a textarea which holds the value default text here for an unimaginably short time followed by the value:

a
b

If you really want to test your browser, I have put this on a JSFiddle at: http://jsfiddle/91mj2arh/

This Fiddle based on your code adds line feeds in my version of IE11, and it seems to acplish what you're looking for to iterate the audio element's properties:

If you post your HTML, we may be able to spot a problem.
