Working example of jQuery UI dialog in a BookMarklet?

Working example of jQuery UI dialog in a BookMarklet?

Hello all,
I was trying to create a simple dialog in jQuery UI in a bookmarklet script.
Thanks to stackoverflow.com I could make a script work but it doesn't work on certain websites, like for example on Wikipedia.

This is the script that I got:

Can you help me to find a better script that works on Wikipedia?

I tried other ways to load jQuery UI but it didn't work for me.

Thanks
