Adding a space to a carriage return line feed in JQuery

Hello experts. I would like to know how to add a space to every Line Space Carriage Return with JQuery.
I have two textarea boxes. I want to take the contents of the original one and add a space to every CR LF into the second one.
This is what I have so far but it's not working correctly:

		var original = $("#myTextbox").val();
		var fixed = original.replace( /[\r\n]+/gm, \n+" " );
		$('#myTextbox2').val(fixed);

Select allOpen in new window

Any guidance is appreciated.
