    Document.write headaches

    Hey gang,

    I'm trying to have a certain piece of html be written into a document
    depending on the browser (specifically, Netscape). Anyway, I have the
    following INSIDE the html (nested in a table) and wonder if this is
    incorrect. Can someone give me some pointers? It's been a while since
    I've done any javascripting and this will help so much. Thank you!!

    <script language="javas cript">
    <!-- hide javascript
    if (navigator.appN ame == 'Netscape'){
    document.write( '<TD align=center height=250><img
    src=media/copyright.gif width=260 height=13 alt= border=0>';
    }

    else {
    document.write( '<TD align=center><i mg src=media/copyright.gif
    width=260 height=13 alt= border=0>';
    }
    // done hiding -->
    </SCRIPT>

      I think that is the original posters problem.

      Because it is illegal HTML. Script tags are HTML tags, and they must
      obey the normal rules for nesting tags. You cannot put a tag *inside*
      another tag, only inside the element (between open and close tags).
      (And as a side note, script tags are only legal inside the head or
      body elements).

      Also, you shouldn't add "px" to the height attribute. Preferably you
      shouldn't use the HTML height attribute, but use CSS styles instead
      (as you say later), or you should just write the number (height="250").

      Type is mandatoty.

      The original poster didn't say which Netscape he is after, and this
      would break in Netscape 4. Apart from that, I would prefer this
      method. The HTML height attribute doesn't use "px".

      It should work, at least if you use CSS (I am not sure how the HTML
      attributes interact with CSS, but proabably reasonably).
      The height of a table cell is the maximum of the specified height and what
      the contents need. The height of a table row is the maximum of its specified
      height and the heights of the cells in that row.

      Absolutely!

          You are right. My brain was in serverside mode.
