View Full Version : Multiple scripts conflicting with each other

Hello everyone,
I've been scratching my head over this one for quite a while.

I'm having trouble running two different scripts on my site- one named accordion and the other named lightbox. I think that it might because of a similar behavior in both the scripts (and if I had to guess I'd say maybe its preload.)

I'd appreciate any help/questions. The page that I'm having the problem with is here: http://lehdesigns.com/bearpaws.html

And here are the codes..

Lightbox

LightboxOptions = Object.extend({
fileLoadingImage: 'images/loading.gif',
fileBottomNavCloseImage: 'images/closelabel.gif',

overlayOpacity: 0.8, // controls transparency of shadow overlay

animate: true, // toggles resizing animations
resizeSpeed: 7, // controls the speed of the image resizing animations (1=slowest and 10=fastest)

borderSize: 10, //if you adjust the padding in the CSS, you will need to update this variable

// When grouping images this is used to write: Image # of #.
// Change it for non-english localization
labelImage: "Image",
labelOf: "of"
}, window.LightboxOptions || {});

// -----------------------------------------------------------------------------------

var Lightbox = Class.create();

Lightbox.prototype = {
imageArray: [],
activeImage: undefined,

// initialize()
// Constructor runs on completion of the DOM loading. Calls updateImageList and then
// the function inserts html at the bottom of the page which is used to display the shadow
// overlay and the image container.
//
initialize: function() {

this.updateImageList();

this.keyboardAction = this.keyboardAction.bindAsEventListener(this);

if (LightboxOptions.resizeSpeed > 10) LightboxOptions.resizeSpeed = 10;
if (LightboxOptions.resizeSpeed < 1) LightboxOptions.resizeSpeed = 1;

this.resizeDuration = LightboxOptions.animate ? ((11 - LightboxOptions.resizeSpeed) * 0.15) : 0;
this.overlayDuration = LightboxOptions.animate ? 0.2 : 0; // shadow fade in/out duration

// When Lightbox starts it will resize itself from 250 by 250 to the current image dimension.
// If animations are turned off, it will be hidden as to prevent a flicker of a
// white 250 by 250 box.
var size = (LightboxOptions.animate ? 250 : 1) + 'px';


// Code inserts html at the bottom of the page that looks similar to this:
//
// <div id="overlay"></div>
// <div id="lightbox">
// <div id="outerImageContainer">
// <div id="imageContainer">
// <img id="lightboxImage">
// <div style="" id="hoverNav">
// <a href="#" id="prevLink"></a>
// <a href="#" id="nextLink"></a>
// </div>
// <div id="loading">
// <a href="#" id="loadingLink">
// <img src="images/loading.gif">
// </a>
// </div>
// </div>
// </div>
// <div id="imageDataContainer">
// <div id="imageData">
// <div id="imageDetails">
// <span id="caption"></span>
// <span id="numberDisplay"></span>
// </div>
// <div id="bottomNav">
// <a href="#" id="bottomNavClose">

Surely there must be a good accordion menu based on jQuery.That's what I would look for.

The first one is Prototype and the other is jQuery. I'm not sure if the 2 frameworks collide.

Maybe finding a different menu would be easier than rewriting the script (I didnt even THINK of getting another menu)- I'm completely baffled by all of it, but willing to learn!

Oh, and I noticed that when I deleted the
</script> right after the first paragraph of code for the accordion script(which would make the menu not work), lightbox would work just fine.

Darn, it does use jQuery. Sheesh, you'd think they would make two applications that use jQuery to be compatible. But still, finding another menu might be easier.
