Slideshow script doesn't work in Opera

**Smoking Man** · 06-04-2006, 12:33 PM

I have a script that runs a slideshow and it works in both IE & FF, but not in Opera. I have run the Javascript console in Opera, but since I'm still learning JS, it's like trying to read Greek. Can someone walk me through this debugger and explain why this script does not work in Opera?

Here's the script:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<html>

<head>

    // Fade effect only in IE; degrades gracefully

    // =======================================
    // set the following variables
    // =======================================

    // Set slideShowSpeed (milliseconds)
    var slideShowSpeed = 4000

    // Duration of crossfade (seconds)
    var crossFadeDuration = 2

    // Specify the image files
    var Pic = new Array() // don't touch this
    // to add more images, just continue
    // the pattern, adding to the array below

    Pic[0] = 'mmMissy062798(1).JPG'
    Pic[1] = 'mmMissy062798(2).JPG'
    Pic[2] = 'mmMissy062798(3).JPG'
    Pic[3] = 'mmMissy062798(4).JPG'
    Pic[4] = 'mmMissy071303(1).JPG'
    Pic[5] = 'mmMissy071303(2).JPG'
    Pic[6] = 'mmMissy071303(3).JPG'
    Pic[7] = 'mmMissy071303(4).JPG'
    Pic[8] = 'mmMissy071303(5).JPG'
    Pic[9] = 'mmMissy071303(6).JPG'
    Pic[10] = 'mmMissy080302.JPG'
    Pic[11] = 'mmMissy110403(1).jpg'
    Pic[12] = 'mmMissy110403(2).jpg'
    Pic[13] = 'mmMissy110403(3).jpg'
    Pic[14] = 'mmMissy110403(4).JPG'
    Pic[15] = 'mmMissy110403(5).JPG'
    Pic[16] = 'mmMissy110403(6).JPG'
    Pic[17] = 'mmMissyWaiting.jpg'
    Pic[18] = 'mmPrettyGirl.jpg'
    Pic[19] = 'missy-endshow.jpg';
        
    // =======================================
    // do not edit anything below this line
    // =======================================

    var t
    var j = 0
    var p = Pic.length

    var preLoad = new Array()
    for (i = 0; i < p; i++){
    preLoad[i] = new Image()
    preLoad[i].src = Pic[i]
    }

    function runSlideShow(){
        if (document.all){
        document.images.SlideShow.style.filter="blendTrans(duration=2)"
        document.images.SlideShow.style.filter="blendTrans(duration=crossFadeDuration)"
        document.images.SlideShow.filters.blendTrans.Apply()      
        }
    document.images.SlideShow.src = preLoad[j].src
        if (document.all){
        document.images.SlideShow.filters.blendTrans.Play()
        }
    j = j + 1
    //  remove comment if you want slideshow to loop, leave comment in for show to play once
    //  commented out > >  if (j > (p - 1)) j=0   
    
    if (j <=(p-1))
      t = setTimeout('runSlideShow()', slideShowSpeed)
    }
</script>


</head>

<body onload="runSlideShow()">

<table>
<tr><td id="VU" height=310 width=415>
        <img src="mmMissy062798(1).JPG" name='SlideShow' width="410" height="308"></td></tr>
</table>

<br />

<div class="info">
    <span>This show will start automatically, and will stop when finished.  Use the "X" at the top of the window to close.</span>
</div>

<br />

</body>

</html>

And this is the error messgae from Opera:

Code:

Missy's Photo Slideshow
http://testdomain.ftwin.com/albums/missy/missy-slideshow.html
Event thread: load
Error:
name: TypeError
message: Statement on line 63: Could not convert undefined or null to object
Backtrace:

    document.images.SlideShow.filters.blendTrans.Apply();

    runSlideShow();
  At unknown location

Any help would be most appreciated.
