Getting class of SVG element in Javascript

[Jacqueline Snook]

Hi,

I am working on a website that uses a SVG diagram with multiple
polygons (to represent rooms in a hotel). Each polygon has a class to
represent whether the room is single or double. In a separate
javascript file, I need to do a different action depending on the
class. How do I read the class in the Javascript file. I tried using
getAttribute("class"), but this does not work - IE comes up with an
error stating 'The object doesn't support this property or method'.

Any help would be greatly appreciated as this is doing my head in!!

Maybe you can give some more information. What do you mean by "each
polygon has a class", do you use a CSS class attribute on the SVG
element, or are you talking about some object-oriented class you have
implemented with JavaScript?
As for your script file, is that embedded in the SVG document or in a
HTML page embedding the SVG document?
Which SVG plugin are you using with IE?
