Hi,

I want to display a tooltip with the author's name when a user mouses over a span. I've noticed that Etherpad Lite already writes a dynamic class that determines the background color of a text span.
Each user has it's own dynamic class with it's own different background color.

The question is: How can I programmatically write another attribute to this user's span?

For instance, we already have:
<span class="author-a-z87zz75zz77zyz66zz73z8z80zdz67zvsz81z2ek">Hello world!</span>

But I want to do this:
<span author-name="Gustavo Scanferla" class="author-a-z87zz75zz77zyz66zz73z8z80zdz67zvsz81z2ek">Hello world!</span>

Another alternative I can think of is:

• Can I get a user name if I know the userId? How? I can already get the ID based on the span class and now I would need to use this ID to find the name but I don't know how...
• There is a JavaScript object available containing all authors?

Thanks in advance!
