Step Three - Change statusbar on mouse events
Please point (no need to click) to the following
link to nowhere
When you point at it you will not see a URL in the status bar as usual,
but you will see a explaination of the link. When you leave the link the
statusbar does not change back to the normal either, but will display
It was defined on the link what script would be called if the mouse
would move over the link and what script would be called when the mouse moves
away from the link.
onmouseover="write_in_statusbar('Link to nowhere');
onmouseout="write_in_statusbar('Not on the link');
return true">link to nowhere<'/a>
As you can see in both cases the same script is called.
The difference is that the function is called with a different value.
So in the script the variable statusbartext would hold the value
that was passed on from the call of the function.
It is then assign to the status of the browser window which is displayed
to the user in the statusbar.
Please note also that there is not only the call of the function in
the definition of the action on the mouseover event.
command that was seperatetd with an semicolon.
The "return true" returns a value to the browser so that it knows that
it does not need to update the status afterwards. Otherwise the browser would show immediatly
after the again the normal status with the URL.
