<rollover> question

[Stephan Petersen <nospam@thanx>]

Hi everybody,

I tried using the rollover tag the other day, referencing it like this:

<rollover name="ecfp2" src="img/ecfp2.gif" overscr="img/ecfp2_a.gif">

WML (V1.7.4, Linux 2.2.5 i686) creates the following code:

[...]
<script type="text/javascript" language="JavaScript">

<!-- Hiding the code
function ro_imgNormal(imgName) {
    if (document.images) {
        document[imgName].src = eval(imgName + "_n.src");
        self.status = '';
    }
}
function ro_imgOver(imgName, descript) {
    if (document.images) {
        document[imgName].src = eval(imgName + "_o.src");
        self.status = descript;
    }
}
// done hiding -->

</script>
<script type="text/javascript" language="JavaScript">

<!-- Hiding the code
if (document.images) {
    ro_img_ecfp2_n = new Image();
    ro_img_ecfp2_n.src = "img/ecfp2.gif";
    ro_img_ecfp2_o = new Image();
    ro_img_ecfp2_o.src = "";
}
// done hiding -->

</script>
<a href=""
   onMouseOver="ro_imgOver('ro_img_ecfp2', ''); return true"
   onMouseOut="ro_imgNormal('ro_img_ecfp2'); return true"
><img name="ro_img_ecfp2" src="img/ecfp2.gif" alt="" width="640" height="60" border="0"></a>
   </tr>

[...]


The problem: since there's no rollover image referenced in the line

ro_img_ecfp2_o.src = "";

the rollover effect doesn't work.

Am I using the rollover tag incorrectly, or what could be the reason for
this?

The image *does* exist on disk, if I edit the html code manually to

ro_img_ecfp2_o.src = "img/ecfp2_a.gif";

it works...



Also, is there away to avoid having a link associated with the rollover? I
just want to have the effect, but no link. As a workaround it's possible
to link to the same page, but is there a more elegant way?

All the best,
Stephan
