Question

my question is how can I get the value of the current selected option

<select id="termid" class="selectfield">
    <option>Επιλέξτε</option>
    <option value="1">Number1</option>
    <option value="2">Number2</option>
</select>

and use it as a PHP variable in $value without submiting or updating the page?

<?php echo get_post_meta($value, "Note1", true); ?>

I made use of this to load a file but I can not do it for the above.

$(document).ready(function() {
    $('#termid').change(function() {
        var val = $(this).val();
        $('#reservationdetails').empty().addClass('loading').load('../' + val + '.php', function(){$('#reservationdetails').removeClass('loading') });
    });
});

Thank you for any help

You should get the value of the selected option:

var val = $('#termid option:selected').val();
