you can use the following function:

  function nl2br (str, is_xhtml) {
     var breakTag = (is_xhtml || typeof is_xhtml === 'undefined') ? '
' : '
';
     return (str + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1' + breakTag + '$2');
  } 

like so:

var mystr="line\nanother line\nanother line";
mystr=nl2br(mystr);
alert(mystr);

this should alert line
another line
another line

the source of the function is from here: http://phpjs.org/functions/nl2br:480

this imitates the nl2br function in php...
