It's a bit of a weird question, to ask somebody to google something for you. If you want to create an auto-populating select box you can find a plugin/tutorial here:

You also mention joomla in your question, as if that is related to the problem you're trying to solve. Do you mean that you want to read information from a joomla component into the select boxes?

You can use any javascript within joomla extensions, so I don't see how that's related to the select boxes.
