new object from user-defined class in IE8

[adampenny]

Hi there,

I've been writing a slideshow script that I've had working perfectly on my mac in Chrome and Safari, however I went to look at it in IE8 and lo and behold it falls over. It says 'object doesn't support this property or method' in relation to the new SlideShow line in the main() function.

I suspect I've missed something incredibly basic, but after a quick google I'm none the wiser.

Thanks for your help. The script is attached.

getElementsByClassName is not supported in all browsers.

Thank you, that would never have occurred to me. I'll give that a go.

My next question is, rather than rewriting the code, would this strategy work, can anyone point me in the right direction for adding the method for the purposes of IE?

I was thinking along the lines of

if(!document.getElementsByClassName)
   {//create a prototype for getElementsByClassName
   }

My questions are

• Is this a viable approach?
• If so, what class should the prototype belong to?
• How do I actually do it? :-/
  
  Under normal circumstances, i'd research it properly, but I'm in a hurry so expert guidance would be gratefully received.
