Javascript : is null or not an object

Question

I was having a problem with IE finding both secure and non-secure items on a page. This seems to have been sorted thanks to a solution by David (many thanks!) who suggested altering the JS we use to display a gallery of images at the top of the page.

The issue now is that the gallery doesn't work!

Here's the error message:

Webpage error details

Message: 'this.galleryData.0.image' is null or not an object Line: 266 Char: 4 Code: 0 URI: https://www.droverholidays.co.uk/scripts/jd.gallery.js

The page is: https://www.droverholidays.co.uk/bikehireform.php

I don't understand JS very well so it would be great if anyone can tell me what I need to do to make this work!

Answer 1

In bikehireform.php change the line that says

startGallery();

to

window.addEvent('domready', startGallery);

Answer 2

In looking at your other question, I personally think CptSkippy's answer is still the correct one.

Stick with the onDomReady approach and make sure your external assets are being loaded from http***s***

Answer 3

Wow... I think I may have got it. I substituted 'load' for 'domready' in Rob's solution, above, and now I don't get the IE warning, and the script works. It seems to be a bit slower than before, would that make sense?
