Target dropdown select with JavaScript?

Hi,

I'd like to display an error message on my form if the user hasn't selected an option from a dropdown list. I'd like to do it with JavaScript.

How can I do that? Thanks

For straight to the point examples I like w3schools approach.

Yes, I tried this, but I don't want an alert message. I'd like to display a text underneath the field.
