I have a problem about which I am very confused. I have a select box with s dynamically generated using a mysqli query:

$result = mysqli_query($db, \"SELECT         


        

Answer 1

just change your function to a 'body'.on, and give your elements an id of 'contacts'

$("body").on('change', '#contacts', function() {
    //get the selected value
    var selectedValue = $(this).val();

    //make the ajax call
    $.ajax({
        url: 'function.php',
        type: 'POST',
        data: {option : selectedValue},
        success: function() {
            console.log("Data sent!");
        }
    });
});
