Is it possible to have a javascript function called
via an Onblur that will insert a <BR> into the value
of a textarea when it encounters a (CR) carriage return?

have a look at this example:

<HTML>
<SCRIPT LANGUAGE="JavaScript"><!--
function remove(str){
 var x = ""
 for (var i=0; i<str.length; i++){
   if (str.charAt(i) == "\n") x += "<BR>"
      else if (str.charAt(i) != "\r") x += str.charAt(i)
 }
 return x
}
//--> </SCRIPT>
<BODY><FORM><TEXTAREA onBlur="this.value=remove(this.value)"></TEXTAREA></FORM></BODY></HTML>

if you have questions, please drop a comment!

It's a nice function!

In a form I have two textareas for which I use this function because i'll print the contens in a new window.

But I would love to make the remove-process somehow in the background, because the resulting single string with all his <br> looks a bit strange for some users.

Is there a way to leave the input-textarea-field untouched, but to write it's content simultaneously in the background to a hidden field, making the remove-process there and print the content-string with his <br> in a new window? The problem I found: There is no "on..."-action possible for a hidden field, right?
