I'm in need of some more help for something quite simple. All I'm trying to get to work is the (onmouseover) portion of the below. I'm sure there is a typo somewhere that I'm not seeing. I've got to quit doing homework when I'm exhausted. Just a little hard after working 12 hour shifts six days a week for the last six months. Thanks.

<a href="manatee.html" onmouseover="self.status='Click here to visit the manatee.' ;return true">Manatee</a><br />
<a href="panda.html" onmouseover="self.status='Click here to visit the panda.' ;return true">Panda</a><br />
<a href="polarbear.html" onmouseover="self.status='Click here to visit the polar bear.' ;return true">Polar Bear</a><br />
<a href="rhino.html" onmouseover="self.status='Click here to visit the rhino.' ;return true">Rhino</a></p>

If all you want is to display a text while mouse is over, you don't need onmouseover event. What you may want to do is title.

<a href="manatee.html" title="Click here to visit the manatee.">Manatee</a><br />
<a href="panda.html" title="Click here to visit the panda.">Panda</a><br />
<a href="polarbear.html" title="Click here to visit the polar bear.">Polar Bear</a><br />
<a href="rhino.html" title="Click here to visit the rhino.">Rhino</a></p>

That's great and I'll take note of it but I'm trying to stick to what my book is telling me. Do you see why the "onmouseover" isn't working?

I just tested your code in the following browsers:

  • IE6 : With return true, shows message onmouseover. With return false, default behaviour then shows message onmouseout. With no return value, behaves as return false.
  • Opera : With return false, shows message onmouseover. With return true, default behaviour then shows message onmouseout. With no return value, behaves as return true.
  • FF : Default behaviour regardless of returned value.

I have read the some browsers have an option to allow/disallow default window.status messages to be overridden, and that the default setting is to disallow. However, none of the browsers tested appears to heve this option (or I missed it).

Conclusion - You can't win!

<a href="manatee.html" onmouseover="self.status='Click here to visit the manatee.' ;return true">Manatee</a><br />
<a href="panda.html" onmouseover="self.status='Click here to visit the panda.' ;return true">Panda</a><br />

<a href="rhino.html" onmouseover="self.status='Click here to visit the rhino.' ;return true">Rhino</a></p>

You don't need a "return true" statement in any of these. You are using the "mouseover event", which doesn't cause the hyperlink to navigate anyway.
There should be no 'returns' at all. <a href="polarbear.html" onmouseover="self.status='Click here to visit the polar bear.' ">Polar Bear</a><br /> will work just fine.
