我想在选择列表中选择一个选项并将代码触发到更改功能。

PHP请求代码:

$la_reservation = $dbh->prepare("SELECT *,
                                          Date_debut, Date_fin, 
                                          client.Nom_societe, Personne_de_contact_idPersonne_de_contact,
                                          IdAdresse, adresse.Rue, adresse.Numero, adresse.Boite, adresse.Code_postal, adresse.Localite, adresse.Pays, adresse.Email, Tel1, adresse.Client_IdClient

                                          FROM bail 
                                          LEFT JOIN reservation ON idBail = Ref_bail
                                          LEFT JOIN client ON bail.Ref_filiale = client.IdClient
                                          LEFT JOIN personne_de_contact ON Personne_de_contact_idPersonne_de_contact = idPersonne_de_contact
                                          LEFT JOIN adresse ON adresse.Client_IdClient = client.IdClient
                                          WHERE idBail = :num_reservation");
            $data = array(":num_reservation"=>$_GET['num_res']);
            //echo str_replace(array_keys($data), array_values($data), $la_reservation->queryString);
            $la_reservation->execute($data);
            $res = $la_reservation->fetch();

我使用$ res ['IdClient']来指示我想在选择列表中选择哪个选项:

<script>$('#liste_clients').val("<?php echo $res['IdClient']?>");</script>

生成的代码是:

<script>$('#liste_clients').val("14");</script>

但更改功能中的警报无效:

$("#liste_clients").change(function(){
alert("here");
 ....
}

使用.on()事件,因为数据会动态添加到页面中。

$(document).on("change", "#liste_clients", function(event){
    alert("changed");
});

试试这个:

<script>
  $(document).ready(function(){
       $('#liste_clients option[value=14]').attr('selected', 'selected');
       $('#liste_clients').trigger('change');
});
</script>
