Hey, Michael!

I don't think JavaScript supports an Else If construction. At least, my
JavaScript book doesn't show one. The statement could be constructed as
follows:

If (item to be tested for true or false value)
   {
   // Code to be run
   }
else
   {
   if (next item to be tested for true or false value)
      {
      // Code to be run
      }
   }

I haven't looked into the hover thing, myself, yet, so can't offer any
advice there. As far as the slow rendering is concerned, do you have the
browser "if" statements sprinkled all the way through your code? If so, that
might account for the slowness if it has to query the browser all the time.
Perhaps it would be better if, at the top of the page, you determined what
type of browser you were using, and then just maintain two seperate versions
of the page to be written out below. That way, only one "if" statement is
executed. Of course, maintainenance then becomes a pain. Nothing's ever
easy, is it?

  Hi folks!



  Sorry I have been so scarce lately – the startup business is keeping me
more than busy for a while now.  The good news is our first site is
launching this week.  No, it’s not the automation site – that’s a few sites
away still.



  Anyway, I hope you guys will pardon an off-topic question.  I figure with
all you guys playing with Mark’s new web stuff, (which I hope to have time
for someday….) that one of you might have some suggestions for me.



  I’m not a Java programmer, and no nothing about it – but I try to fake it.
J  Anyway, I have needed to use a fair amount of on our first site.  Now I
need to change the “bookmark message” at the bottom of the screen, and I’m
not sure how to do it.



  Here’s what I was thinking:



  <!--

  if ((navigator.appVersion.indexOf("MSIE") > 0)

    && (parseInt(navigator.appVersion) >= 4))

  {

  document.write("<U><SPAN
STYLE='color:black;cursor:hand;'onclick='window.external.AddFavorite(locatio
n.href,document.title);'>Click to add this page to your
Favorites!</SPAN></U>");

  }

  else if ((navigator.appVersion.indexOf('Netscape') != -1)

    || ((navigator.appVersion.indexOf("MSIE") > 0)

     && (parseInt(navigator.appVersion) < 4)))

  {

  document.write("<B>Hit Control-D to Bookmark this page!<B>");

  }

  else

  {

      document.write("<B>Bookmark this page now!<B>");

  }

  //-->



  Of course, it doesn’t work right from the “else if” on.  Is that the way
to do an “else if” in Java?



  Also, I’d like to do a color-change-on mouse-hover in the first section of
the code, but can’t figure out how to do it.  I use hover effects on all the
links on the site (for those with MSIE), and I’d like this link to do the
same thing.



  Any advice you guys can offer would be appreciated.



  BTW, is it me, or is the Netscape browser (4.73) rather buggy?  Trying to
code html for both browsers has been a real pain.  Much of the java I have
used senses which browser is being used, and slightly alters the page
accordingly.  And, it sure renders slow.   Is there something I’m missing
here?



  Cheers!
