Question

我希望在有人点击MySQL html，

后显示select option的值

但我可以使用提醒尝试。

我已经看过这个post，但我无法使用，

JS：

function choice1(select) {
    alert(select.options[select.selectedIndex].text);
}

这是我的选择：

<select name="tanggal_input" id="test-dropdown" onchange="choice1(this)">
<?php 
    while ($row = $tgal->fetch(PDO::FETCH_ASSOC))
    {
        echo '<option value="'.$row["tgl_input"].'">'.$row["tgl_input"].'</option>';
    }
?>
</select>

<table width="100%" class="table table-striped table-bordered" id="tabeldata">
                <thead>
                    <tr>
                        <th width="30px">No</th>
                        <th>Alternatif</th>
                        <th>Kriteria</th>
                        <th>Nilai</th>
                        <th width="100px">Aksi</th>
                    </tr>
                </thead>

                <tfoot>
                    <tr>
                        <th>No</th>
                        <th>Alternatif</th>
                        <th>Kriteria</th>
                        <th>Nilai</th>
                        <th>Aksi</th>
                    </tr>
                </tfoot>

                <tbody>
        <?php
        $no=1;
        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
        ?>
                    <tr>
                        <td><?php echo $no++ ?></td>
                        <td><?php echo $row['nama_alternatif'] ?></td>
                        <td><?php echo $row['nama_kriteria'] ?></td>
                        <td><?php echo $row['nilai_rangking'] ?></td>
                        <td class="text-center">
                            <a href="rangking-ubah.php?ia=<?php echo $row['id_alternatif'] ?>&ik=<?php echo $row['id_kriteria'] ?>" class="btn btn-warning"><span class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a>
                            <a href="rangking-hapus.php?ia=<?php echo $row['id_alternatif'] ?>&ik=<?php echo $row['id_kriteria'] ?>" onclick="return confirm('Yakin ingin menghapus data')" class="btn btn-danger"><span class="glyphicon glyphicon-trash" aria-hidden="true"></span></a>
                        </td>
                    </tr>
        <?php
        }
        ?>
                </tbody>

            </table>

这是函数（rangking.inc.php）：

function readHasil($a){

        $query = "SELECT sum(bobot_normalisasi) as bbn FROM " . $this->table_name . " WHERE
        id_alternatif='$a' and tgl_input = '2017-05-23' LIMIT 0,1";
        // i need to get tgl_input = "..." from option select value
        $stmt = $this->conn->prepare( $query );
        $stmt->execute();

        return $stmt;
    }

function readHasil($a){

        $query = "SELECT sum(bobot_normalisasi) as bbn FROM " . $this->table_name . " WHERE id_alternatif='$a' and tgl_input = '2017-05-23' LIMIT 0,1";

        $stmt = $this->conn->prepare( $query );
        $stmt->execute();

        return $stmt;
    }

问题：我需要从选项选择中获取值到我的函数PDO，并在有人点击选项选择时在同一页面中执行查询。

我该怎么做？有一些例子吗？

编辑：我没有使用其他文件来显示结果，例如某人标记重复的帖子，因为所有结果都是在这样的1个php文件中

<?php
include_once 'includes/rangking.inc.php';
$pro = new Rangking($db);
$stmt = $pro->readKhusus();
?>

---some html code-----

<?php
        $no=1;
        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
        ?>
                    <tr>
                        <td><?php echo $no++ ?></td>
                        <td><?php echo $row['nama_alternatif'] ?></td>
                        <td><?php echo $row['nama_kriteria'] ?></td>
                        <td><?php echo $row['nilai_rangking'] ?></td>
                        <td class="text-center">
                            <a href="rangking-ubah.php?ia=<?php echo $row['id_alternatif'] ?>&ik=<?php echo $row['id_kriteria'] ?>" class="btn btn-warning"><span class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a>
                            <a href="rangking-hapus.php?ia=<?php echo $row['id_alternatif'] ?>&ik=<?php echo $row['id_kriteria'] ?>" onclick="return confirm('Yakin ingin menghapus data')" class="btn btn-danger"><span class="glyphicon glyphicon-trash" aria-hidden="true"></span></a>
                        </td>
                    </tr>
        <?php
        }
        ?>

从选项值中获取值并使用它来点击使用javascript后从pdo函数执行查询
