I am trying to get the Youtube Classic Viewer userscript to operate:


Unfortunately, script will not run because I don't have getElementsByClassName in my browser webkit.

I tried adding a generic getElementsByClassName snippet, but it doesn't work as a subsidiary function,

(i.e.) parentObject.getElementsByClassName("class name")[i]

"is not a function." -- javascript error console message

even when I insert a javascript library snippet at the bottom of the script (I tried several snippets from back before the function became standard in recent browsers).

Anyone have a javascript library version I can add to the userscript to get it to work, or do I have to upload it in some other fashion?

Bear in mind, I'm not too knowledgeable about Javascript, especially when it comes to object handling and adding in built-in functions.
