I was under the impression that I could get the value of a select input by doing this $(this).val(); and applying the onchange parameter to the sel
$(this).val();
onchange
This is helped for me.
For select:
$('select_tags').on('change', function() { alert( $(this).find(":selected").val() ); });
For radio/checkbox:
$('radio_tags').on('change', function() { alert( $(this).find(":checked").val() ); });
