task:
 turn js line breaks inside HTML Textarea tag into HTML line breaks, <br/>

code:
// el stand for document id
	var lb = function(el) {
	var pa = document.getElementById(el).value;
	pa = pa.replace(/\n/g,'\n<br/>');
	document.getElementById(el).value = pa;
}

outcome:
(1) tested with Firefox 50 for Windows, the very first instance of the Textarea behaved as expected, however, the function added two line breaks for another Textarea element that I hit Enter only once.
(2) tested with Safari v5.1.7 for Windows, I got inconsistent results (my target users for this particular app won't use this browser), so, I can ignore it.
(3) would love to test with Chrome, however, Chrome keeps on crashing on my current laptop.

Another thing:
It's not elegant to bring the <br/> down to next line...

Thoughts?  Thanks as always.
