Text mouseover for fade scroller

[Jeroen94]

1) Script Title: Fade scroller

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...fadescroll.htm

3) Describe problem: Is it possible to program a text mouseover for the fade scroller (in order to some extra information when one moves with the mouse over the text in the scroller)?

[jscheuer1]

OK, try out this version (includes the pause onmouseover from before):

Demo

Code:

<script type="text/javascript">

Notice the highlighted lines. That's where you configure the mouseover texts.

Thanks, it works perfectly again!

But, the mouseover text dissapears after a while. Isn't it possible to let it be visible the whole time, until one moves the mouse out of the scroller?

[Jeroen94]

Oh and something else too: how can I create paragraphes in the mouseover text? The <br> function doesn't work...

For exemple: when I write

fctitles[0] = "What's New?<br>I don't know"; one reads "What's New?<br>I don't know" in the mouseover text.

[jscheuer1]

It's just a title attribute. You can't use HTML. You can use \n to create a new line:

fctitles[1] = "Dynamic Drive\nRecommended!";

And for the same reason (it's just a title), you can't control how long it appears for.

With something like this, shouldn't the main content be in the scroller anyway?

If not, we might want to try incorporating a tooltip script or possibly even a popup content script or popup menu script.

At that rate though, if the real content is in the popup, maybe you don't need a scroller. Perhaps just having keywords in ordinary text on the page would be better triggers for whatever type of popup you decide to use.

[Jeroen94]

The tooltip script seems a very good option, because it doesn't dissapear after a while. Is it possible to fit it in the fade scroller script?

Pick one from here:

or elsewhere from around the web.
