How do I populate a series of text fields using Javascript based on a pulldown selection

Head out to http://hihatwebdesign.com/vbs/student_insert.php.

What needs to happen is the user can potential select from a list of families in the "family id" pulldown. If they make a selection, all of the corresponding fields are automatically populated with the info corresponding to the family they selected.

Also, I need a button to appear, should they make a selection, that allows them to clear the info, but only the info effected by the "family id" pulldown (address, city, state, zip, phone, cell, email, alt email, home church, subdivision).

What would the Javascript function look like?

I know I need an "on change" dynamic in the pulldown, but I'm lost as far as how to incorporate a MySQL statement in the midst of the Javascript.

What do you think?

for your button : <input type="button" id="buttonID" value="reset fields" />
And in head section :
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
jQuery(function($) {
    $("#buttonID").click(function() {
         $("[name='f_last_name'],[name='address'], and so on ,[name='subdivision']").val();
    });
});
</script>
