Conveyor Belt slideshow Does Not Work

**NightZEN** · 11-04-2007, 07:08 PM

Script name: Conveyor Belt slideshow
url: http://www.dynamicdrive.com/dynamici...rightslide.htm

Problem:
I have inserted this script into my webpage, and it does not work. Do I have to change something in the header to allow for dhtml to work correctly? Any help you can give me would be great!

Header:

Code:

<html><head>
<title> Purr Toys
</title>
<link href="/images/favicon.ico" type="image/x-icon" rel="icon"/><link href="/images/favicon.ico" type="image/x-icon" rel="shortcut icon"/>

<link rel="stylesheet" href="/colbox6.css" type="text/css">

<meta content="MSHTML 6.00.5730.11" name=GENERATOR>

</head>

Code in question, as it renders on my site:

Code:

<script type="text/javascript">

//Specify the slider's width (in pixels)
var sliderwidth="500px"
//Specify the slider's height
var sliderheight="150px"
//Specify the slider's slide speed (larger is faster 1-10)
var slidespeed=3
//configure background color:
slidebgcolor="#000000"

//Specify the slider's images
var leftrightslide=new Array()
var finalslide='<a href='/servlet/Detail?no=65&sfs=7f102b9f'><img src="/catalog/erosBodyGlide_100.jpg" width="100" border="0"></a>'

Two things jump out:

var finalslide=''

shouldn't be defined (maybe not even declared), I have no idea why it was ever included in the release version of the code (I didn't write it). Just leave it as it is on the demo page (declared but with no value), just to be on the safe side.

Next, and more important, you cannot do this (red):

Code:

leftrightslide[0]='<a href='/ser

because the moment you do, it closes the array entry that was opened with leftrightslide[0]=' prematurely.

So instead of:

Code:

leftrightslide[0]='<a href='/servlet/Detail?no=65&sfs=9573f9ff'><img src="/catalog/erosBodyGlide_100.jpg" width="100" border="0"></a>'

and all similar, use:

Code:

leftrightslide[0]='<a href="/servlet/Detail?no=65&sfs=9573f9ff"><img src="/catalog/erosBodyGlide_100.jpg" width="100" border="0"></a>'

There could be other problems.

Also, that's a pretty old script, though that's probably not any part of the problem. Still, here is another version, also old, just not as old:

http://home.comcast.net/~jscheuer1/s...onveyor_oo.htm

If you still need help, to give us more of a fighting chance:

Please post a link to the page on your site that contains the problematic code so we can check it out.

It's so much easier to debug code that's live.

Thanks John!

My site is (unfortunatly) hosted by ProStores (owned by ebay) and uses a custom markup language (SSML) to hit the database. It is with this SSML that I create the hyperlinks causing the single quote issue. In other words - I cannot change the links directly as I have it coded now.

Your info is valuable, however. Thanks for the insight! I will have to take a while to think my way around this and cod it a different way - SSML has some crappy limitations.

As long as there are no spaces in the href value, this would be acceptable (as far as the script is concerned):

Code:

leftrightslide[0]='<a href=/servlet/Detail?no=65&sfs=9573f9ff ><img src="/catalog/erosBodyGlide_100.jpg" width="100" border="0"></a>'

And, this will work, if allowed:

Code:

leftrightslide[0]='<a href=\'/servlet/Detail?no=65&sfs=9573f9ff\'><img src="/catalog/erosBodyGlide_100.jpg" width="100" border="0"></a>'

**jscheuer1** · 11-04-2007, 09:36 PM

Oh, there's more, you could do this:

Code:

leftrightslide[0]="<a href='/servlet/Detail?no=65&sfs=9573f9ff'><img src='/catalog/erosBodyGlide_100.jpg' width='100' border='0'></a>"

John,
Thanks for your help above - with it, I was able to get this code working. I'll give you the url, but it is not live yet. Check back in a few weeks on a product page to see it if you like:

Thanks Again,
