jQuery: Load data on a combo box depending on another

I have two combo boxes.

Let's say the first one had valu开发者_开发问答es A, B, C

And when I select A the second one should show me options 1, 2, and 3

If I select B, then the second one should have the options 4, 5, and 6

and C should make the second combo box have the options 96, 98, 100.

Is there a way to do this via jQuery?? Thank you very much!
