我有一个选项列表，我想在其中导航到每个列表选项的每个页面。我可以知道怎么做吗？我只是尝试了路由器选项而所有的方法都不起作用。导航栏和页脚已设置在固定位置，背景区域中的内容应根据导航栏中的菜单选择进行更改。

您应该使用function update(){
if($this->input->post('submit')){
$id_user = $this->input->post('id');
$username = $this->input->post('username');
$cek = $this->db->query("SELECT id_user, username, password, nama FROM user WHERE role = 'users' AND id_user = '$id_user'");
$cek2 = $this->db->query("SELECT username FROM user WHERE role = 'users' AND id_user = '$id_user' AND username='$username'");
if($cek2->num_rows() == 1){
echo '<script type="text/javascript">';
echo 'alert("Username is invalid.");';
echo 'window.location.href = "'.$_SERVER['HTTP_REFERER'].'";';
echo '</script>';
}elseif($cek->num_rows() == 1){
$nama = $this->input->post('nama');
$new_password = md5($this->input->post('new_password'));
$conf_password = md5($this->input->post('conf_password'));
$status = $this->input->post('status');
if(strlen($new_password) > 0){
if($new_password != $conf_password){
echo '<script type="text/javascript">';
echo 'alert("Failed to update, new password is invalid!");';
echo 'window.location.href = "'.$_SERVER['HTTP_REFERER'].'";';
echo '</script>';
}else{
$data_update = array(
'nama' => $nama,
'username' => $username,
'password' => $new_password,
'status' => $status
);
$this->db->where('id_user',$id_user);
$this->db->update('user',$data_update);
$this->session->set_flashdata('item', array('message' => 'Success!','color' => 'info'));
redirect('user');
}
}else{
$data_update = array(
'nama' => $nama,
'username' => $username,
'status' => $status
);
$this->db->where('id_user',$id_user);
$this->db->update('user',$data_update);
$this->session->set_flashdata('item', array('message' => 'Berhasil mengubah data!','color' => 'info'));
}
}else{
echo '<script type="text/javascript">';
echo 'alert("Failed to save!");';
echo 'window.location.href = "'.$_SERVER['HTTP_REFERER'].'";';
echo '</script>';
}
}else{
echo '<script type="text/javascript">';
echo 'alert("Failed to save!");';
echo 'window.location.href = "'.$_SERVER['HTTP_REFERER'].'";';
echo '</script>';
}
}
而不是通用路由方法。让我给一个示例代码
navigateByUrl<ul class="dropdown-menu">
<li (click)="goToPage('account')">My Account</li>
</ul>
希望这对您有帮助
