Can someone help me with this code, please?

Hi

I have this JavaScript which seems to work OK in NN 7.x on the Mac but refuses to even do anything on IE on the Mac.

To see what I am trying to do, please goto www.c-c-strange.biz, go to the Photographs page and then the Christchurch link.

The caption to the right of the photo is currently a jpeg, I want to change it to html.

As I say, this works in Netscape:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<title>Christchurch Scenes</title>

<removed style setting to save space>

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

</script>

</head>
<body>

<div id="navcontainer">
<ul id="navlist">
<li><a href="../index.html">Home</a></li>
<li><a href="../photographs.html">Photographs Index</a></li>
</ul>
</div>
<div id="picbox">
<img id="mypic" src="02.jpg" alt="" width="255" height="383" border="1" />
</div>

/*<div id="capbox">
<iframe src="Cap02.html" id="captxt" width="300" height="389" frameborder="no"></iframe>
</div>
*/
<div id="navbuttons">
<a href="JavaScript:slideshowBack()"><<Back | </a>
<a href="JavaScript:slideshowNext()">Next>></a>
</div>

</body>
</html>

Any help for this newbie would be greatly appreciated.

Thanks in advance

Tested the page in Mozilla and IE. Like you said it doesn't work in IE but works okay in Mozilla. When I press "Next" on IE an error message shows up saying that "Interval" is undefined

Code:

function rotateImage(place, placeCap) {
  var new_image = getNextImage();
  document[place].src = new_image;
  var new_cap = getNextCap();
  document[placeCap].src = new_cap;
  var recur_call = "rotateImage('"+place+"')";
  timerID = setTimeout(recur_call, interval); // this line!
}

Try putting this line before the timerID = ... code:

Code:

  var interval = 15000;

Hope that helps.

Thanks, I will take note of that and change it if I have to stick with the existing setup. But that code is from the current way I am doing things. It is the code that I posted in my original post that is the real problem - because I would really like to make the captions html and not jpegs.

Thanks

Cliff

Oops, I just assumed that they were the same code. My apologies.

BTW, what exactly isn't working in IE? I noticed that you have the caption text loader code commented out...

If it's the caption loader, you may like to try giving the <iframe> a name attribute e.g. <iframe name="captxt" id="captxt"></iframe> and then in your javascript do something like:

Code:

 document.mypic.src=eval("image" + num+ ".src" );
window.open( eval( 'text'+num), 'captxt'); // this is the new code

Cheers~

Thanks Aska! That was the clue I needed.

I gave the iframe a name as well as an id, and it worked (with my existing code).

I had commented out the code to try and resolve what wasn't working, and I unfortunately forgot to uncomment it when I posted it to this forum.

But your suggestion of using name as well as id made it work :-)))

Is there a good place to find out about all the differences in JavaScript between browsers. I now find it doesn't work so well in either Safari or Opera. But I think I could track that down if I had some reference material.

Many thanks for your help.

Glad to help~

Good reference if you are after a list of functions:
http://www.devguru.com/Technologies/...ipt_index.html

This site shows what works in what browsers (click on the links on the right hand side of the page) - however doesn't say much about browsers other than IE/NN.
http://www.irt.org/xref/index.htm

I'd be interested if other people knows of any site that lists/compares the differences in JavaScript/DOM across different browsers.
