Question

我需要在鼠标悬停时使用数据库（如下图所示）从数据库中获取和显示数据，并在鼠标关闭时消失。

这是模型

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();
}

控制器

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

查看： -

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>';
}

我希望在鼠标名称显示时显示邮寄地址和电子邮件地址

Answer 1

使用title属性：

echo "<tr>";
echo "<td>".$locate['computer_number']."</td>";
echo "<td title='".$locate["email"]."<br />".$locate["address"]."'>".$locate['name']."</td>";
echo "<td><img src=". base_url()."inc/images/confirm.png width='45' height='30' border='0' class='computer_number' data-id='".$locate['computer_number']."'/></td>";
echo "</tr>";
