Inserting a newline into a pre tag (IE, Javascript)

Question

In IE when I insert text into a

 tag the newlines are ignored:






        

Answer 1

I reckon this.

What I found was IE is using \r\n and Fx(others) is using \n

var newline;
if ( document.all ) newline = '\r\n';
else newline = '\n';

var data = 'firstline' + newline + 'second line';
document.getElementById("putItHere").appendChild(document.createTextNode(data));

For a TinyMCE(wysiwyg editor) plugin I once made I ended up with using BR i edit mode and cleaned it up on submit etc.

This code loops through all BR elements inside PRE elements and replaces BR with newlines.

Note that the code relies on the TinyMCE API, but can easily be written using standard Javascript.

Clean up:

        var br = ed.dom.select('pre br');
        for (var i = 0; i < br.length; i++) {
          var nlChar;
          if (tinymce.isIE)
            nlChar = '\r\n';
          else
            nlChar = '\n';

          var nl = ed.getDoc().createTextNode(nlChar);
          ed.dom.insertAfter(nl, br[i]);
          ed.dom.remove(br[i]);
        }

Good luck!
