if s = form.elements['recipient[]'] then s.length contains the number of
options in the select. The first option will be s.options[0]... if
s.options[0].selected then it got selected :-)
...and, OK, here's a script -- if your form contains
<select name="likes[]" size="4" multiple>
<option value=1>Chocolate
<option value=2>Fruit
<option value=3>Fast foods
<option value=4>Healthy foods
</select>
...then you need...
lk = boxform.elements['likes[]'];
l = lk.length;
msg = '';
for (i=0; i<l; i++)
if (lk.options[i].selected) msg += 'Picked option ' +
lk.options[i].value + '\n';
if (msg == '') msg = 'No likes were selected';
alert(msg);
