Javascipt to validate a form button

Hi guys, I have a quick one here, can you help me validate a search text box?

I have a submit button and reset button within a search form, and I would like to, once the submit button is clicked for it to make sure they have not left the text field blank.

Can you help with the function? Thanks,

David.
