    Thanks David,

    That is the method I went with. I stuck a <div id="makeitHere" </div>
    into my HTML doc, then was able to find that in the javascript and use
    the appendChild to stick that text area in there precisely where I
    wanted it. Works great.

    Now I have a flag I can set to say whether I am on FF with firebug
    loaded, in which case all my debug messages go to that console. When in
    another browser without firefox & a console, the flag is set
    differently and the textarea pops up and all my error messages go into
    that textarea.

    I don't use IE at all, so any extra complexities from those
    troublemakers aren't an issue ;-)

    Ross.

      You mean without an error console. Firebug is optional.

      That is sensible.

      Is there some means to make that form part display conditionally?  Any
      Yes, the simplest way is to use the document.write method.

      Document: write() method - Web APIs | MDN
      https://developer.mozilla.org/en/DOM/document.write
      The write() method of the Document interface writes text in one or more TrustedHTML or string parameters to a document stream opened by document.open().


      You could also create the form using document.create Element and add it
      to the DOM with appendChild. Unfortunately, IE makes this method more
      difficult than it should be.

        How to create a textarea dependant on flag in javascript

        When I sometimes want to debug something on a browser without a firebug
        console, I have been using a textarea to which I can print stuff.

        So my HTML calls my big script file, and further down in my HTML I put
        up a textarea. When a 'debug' condition in my .js is in modeOne, I
        write msgs to that textarea. When it's in modeTwo, I write to the
        firebug console, in modeThree no messages get written.

        I'd like to have that textarea not visible in the latter two modes.

        SO my html contains:

        <html>
        ....
        <script type='applicati on/x-javascript' src='/myfiles/dowork.js'>
        </script>
        ....
        other html
        ....
        <form name="mydebug">
        DEBUG Data:
        <textarea rows="40" cols="30" name="outdebg"D ebug msgs:
        </textarea>

        </form>
        </html>


        Is there some means to make that form part display conditionally? Any
        suggestions for a newbie? I suppose moving it into the javascript makes
        sense, where an if-statement can be used. But then how does one make a
        textarea like that show up?

        Thanx

        Ross.
