Having issues with IE8 and SmoothGallery script errors

I'm currently utilizing the SmoothGallery plugin created by Jon Designs to enhance the website of one of my clients. However, there seems to be a minor issue in Internet Explorer 8 when attempting to navigate to the next image. Interestingly enough, after conducting tests on various browsers, it appears that IE is the only one where this problem occurs.

Isn't that just typical?

I've been diligently investigating the root cause of this predicament, but unfortunately, I only receive an error within the eval-function of the mootools library which forms the foundation of this gallery. As a result, I haven't had much luck pinpointing the exact source of the issue.

Is there any possibility of setting up an "All-Exceptions Breakpoint," similar to what can be done in Xcode? This would allow me to identify the specific line of code where the hang-up occurs. Alternatively, does anyone have insights into what might be happening here?

The corresponding site can be accessed via , and the responsible JS file for the gallery can be found at

I sincerely appreciate any assistance provided.

Answer №1

You have an extremely outdated version of mootools - 0.89 or 1.0, if I remember correctly. It's packed with evals using dean edwards' PACKER, which makes it very difficult to debug.

The code for instantiating is quite messy and monkey patched:

function startGallery17() {
    if (window.gallery17) {
        try {
            var myGallery17 = new gallery($('myGallery17'), {
                timed: false,
                showArrows: true,
                showCarousel: false,
                textShowCarousel: 'Thumbnails',
                embedLinks: false,

                lightbox: true
            });
            var mylightbox = new LightboxSmoothgallery();
        } catch (error) {
            window.setTimeout("startGallery17();", 2500);
        }
    } else {
        window.gallery17 = true;
        if (this.ie) {
            window.setTimeout("startGallery17();", 3000);
        } else {
            window.setTimeout("startGallery17();", 100);
        }
    }
}
window.onDomReady(startGallery17);

The use of strings in setTimeouts also causes evals here, and the try blocks will prevent you from getting any useful error feedback.

If you want to solve this issue, remove these hacks and load a newer but still old version of mootools like this one: https://ajax.googleapis.com/ajax/libs/mootools/1.11/mootools.js, or preferably, try version 1.12 and see if debugging becomes easier.

After that, remove the try/catch blocks and use window.addEvent('domready', fn) to start your code - or if you depend on images being loaded, consider using window.addEvent('load', fn) instead.

If all you're doing on the page is stacking up some images with a next/previous functionality, why not use the latest mootools with a new plugin - there is absolutely nothing beneficial about what you've chosen.

For example, take a look at this tutorial I wrote on how to do it: , or search on the forge for something packaged: .

You should be fine with version 1.4.5 (the latest one).

Keep in mind that the version you're currently using will likely break in IE9 and the latest Gecko-based browsers.
