Javascript codeigniter，如何显示悬停文本的详细信息

当鼠标移到数据库上时，我需要使用下面视图中显示的表从数据库中获取和显示数据，当鼠标关闭时，该表将消失

这是模型

控制器

视图：-

---

我想在鼠标悬停在name上时显示邮政地址和电子邮件地址

想在鼠标悬停时显示整个表格吗？您介意提及要在其上触发悬停元素的任何DOM元素吗？。

public function teacher_with_subject(){
    $this->db->select('*')
    ->from('teacher AS t')
    ->join('teacher_subject ts','t.computer_number=ts.computer_number', 'left')
    ->where('t.date_of_termination','0000-00-00')
    ->where('ts.date_of_end','0000-00-00');
    $query = $this->db->get();  return $query->result_array();
}

$located=$this->select_model->teacher_with_subject();

if (count($located) > 0) {
    echo '<table>';

    foreach($located as $locate){
        echo "<tr><td>".$locate['computer_number']."</td><td>".$locate['name']."</td><"</td><td><img src=". base_url()."inc/images/confirm.png width='45' height='30' border='0' class='computer_number' data-id='".$locate['computer_number']."'/></td></tr>";
    }
    echo '</table>';
}
