nl2br equivalent

[Gregory]

Is there a javascript equivalent of PHP's nl2br() function? I have to send the value of a textarea to a new window that will display the text of what was in the box, which is why I need to somehow convert newlines to breaks.

Thanks,
Greg

There's nothing built-in, but you can write your own nl2br function:

function nl2br(someText) {
  return someText.replace("\n", "<br />");
}

Thanks!

That seemed to work, but for the first linefeed only. I figured out the solution is to make a loop that repeats the function until the end of the textarea.

A better solution than a loop would be to use a Regular Expression with the g (global) and m (multi-line) parameter:

function nl2br(someText) {
   	return someText.replace ( /\n/gm, '<br />' );
   }

Ahh...that is better! Thanks, Mr. Brownstone.

I use theses

String.prototype.nl2br = function()
{
	return this.replace( /\n/g, "<br />" );
}

String.prototype.br2nl = function()
{
	return this.replace( /\<br ?/?\>/g, "\n" );
}
