我需要在健身房设置一个四阶运动选项，所以我必须使用四个下拉菜单，我从数据库中检索数据列表，这是一个阵列drom数据库，当我选择fisrt一个包含30个学科在第一个下拉列表中，seconde下拉列表不包含这个值，而且当我从第3个下拉列表中选择一个值时，这个下拉列表不会包含来自dropdown1和dropdown2的value1和value2，同样关于下拉列表4它必须只包含来自数据库的27个值
我的模特：participantport_m.php：
public function get_new()
{
$participant_sport = new stdClass();
$participant_sport->nom = '';
$participant_sport->prenom = '';
$participant_sport->trimestres = '';
$participant_sport->sport_ordre1 = '';
$participant_sport->sport_ordre2 = '';
$participant_sport->sport_ordre3 = '';
$participant_sport->sport_ordre4 = '';
$participant_sport->sport_montant_paye = '';
$participant_sport->sport_debut_periode = '';
$participant_sport->sport_fin_periode = '';
return $participant_sport;
}
function get_discipline_sport() {
$this ->db->select('id, nom_discipline');
$query = $this ->db->get('disciplines_sport');
$salles = array();
if ($query->result()) {
foreach ($query->result() as $discipline) {
$disciplines[$discipline->id] = $discipline->nom_discipline;
}
return $disciplines;
} else {
return FALSE;
}
}
数据库的结构： id - nom_discipline - tarif_discipline - description
我的控制器agent.php：
public function inscriresport ($id = NULL)
{
// Fetch a participant or set a new one
if ($id) {
$this->data['participant_sport'] = $this->participantsport_m->get($id);
count($this->data['participant_sport']) || $this->data['errors'][] = 'Agent non trouvé';
// explode to array
// print_r($this->data['participant_sport']['trimestres[]']); // test before explode
$this->data['participant_sport']->trimestres = explode(",", $this->data['participant_sport']->trimestres);
// print_r($this->data['participant_sport']['trimestres[]']); // test after explode
}
else {
$this->data['participant_sport'] = $this->participantsport_m->get_new();
}
// Set up the form
$rules = $this->participantsport_m->rules_participantsport;
$this->form_validation->set_rules($rules);
// Process the form
if ($this->form_validation->run() == TRUE) {
$data = $this->participantsport_m->array_from_post(array('nom', 'prenom', 'beneficiaire', 'trimestres' , 'sport_ordre1', 'sport_ordre2', 'sport_ordre3', 'sport_ordre3', ,'sport_montant_paye', 'sport_debut_periode', 'sport_fin_periode'));
$this->participantsport_m->save($data, $id);
redirect('admin/agent/profile/3608');
}
// Load the view
$this->data['subview'] = 'admin/agent/inscriresport';
$this->load->view('admin/_layout_main', $this->data);
}

我需要怎样才能通过javascript做到这一点我是javascript的新手，我不知道我从哪里开始，任何帮助plsease？非常感谢。
答案 0 :(得分：0)
我建议在所有下拉列表中包含所有体育项目，当您想要提交表单时，请检查是否有任何相同的值下拉列表。你可以通过以下方式获得它们：
var flag = false;
var e1 = document.getElementById("dropdown1 id");
var value1 = e1.options[e1.selectedIndex].value;
var e2 = document.getElementById("dropdown2 id");
var value2 = e2.options[e2.selectedIndex].value;
...
if(value1 != value2 && ...)
{
flag = true;
}
if(flag)
{
// Stuff
}
