Question

我正在生成具有许多列的动态行。一栏有4个按钮，每个按钮具有不同的FORM操作。我想使用ajax更新“行”详细信息。

此文件为dashboard.php

<?php
session_start();
include('database_connection.php');

$start = 0; 
$size = 10;

$sql_display = "SELECT id, fullname, gender, verified FROM student LIMIT $start, $size";
$result = $db->query($sql_display);

?>
<html>
<body>
    <table border='2px'>
    <thead>
        <tr>
            <th>#</th>
            <th>Name</th>
            <th>Gender</th>
            <th>Status</th>
            <th>Issue</th>
            <th>Remark</th>
        </tr>
    </thead>
    <tbody>
        <?php
            if ($result->num_rows > 0) {
            while($row = $result->fetch_assoc()) {

                  echo "<tr><th scope='row'>". $idd=$row['id'] ; /*Displaying the ID to the dashboard*/
            echo '</th><td>';
                echo $row['fullname'];
            echo "</td><td>";
                if( $row['gender']=='1' )
                    echo "Female";
                else
                    echo "Male";    
            echo "</td><td>";   

            /*The value i want to change from Not Issued to Issued when user clicks Issue button*/
                if($row['verified']=="1" )
                    echo "Issued";      
                else
                    echo "Not Issued";
            echo "</td><td>";

                echo "<form method='POST'>
                <!--===The id is used to select the entry uniquely from SQL Table===-->>
                <input type='hidden' name = 'id' value = ".$idd .">
                <input id='update' type = 'submit' class='bg-green' name= 'verify_it' value='Issue'><br/>

                </form>

                <form action='edit.php' method='POST'>

                </form>
                ";
            ?>
        <form action='delete.php' method='POST' onsubmit="return confirm('Are you sure you want to submit?');" >
        <?php

            echo "

            <input type='hidden' name = 'id' value = ".$idd."></input>
            <input type='submit' class='bg-blue' name='update_remark' value='Remark' style='width:80%;'/>
            </form>";
            echo "</td></tr>";
            }
            }//end if
            ?>
        <html>
            <tr>
                <th scope="row">-</th>
                <td>-</td>
                <td>---</td>
                <td>---</td>
                <td>---</td>
                <td>---</td>
            </tr>
            </body>
        </html>

这是更新文件：

<?php
session_start();

if ($_SERVER['REQUEST_METHOD'] === 'POST') {

// database connection

include ('database_connection.php');

// checking which button clicked

if (isset($_POST['verify_it'])) {
    $var_id = $_POST['id'];
    $status_check = "SELECT verified, fullname, email FROM student WHERE id = '$var_id' LIMIT 1";
    $s_check = $db->query($status_check);
    $s_value = $row = $s_check->fetch_assoc();
    if ($s_value['verified'] == "0") {
        $sql_update_status = "UPDATE student SET verified = 1 WHERE id='$var_id' ";
        $db->query($sql_update_status);
        $_SESSION['fullnameemail'] = $s_value['fullname'];
        $_SESSION['emailid'] = $s_value['email'];
        //include ('PHPMailer/sendmail.php');

        if ($_SESSION['dashboard'] == "true") {
        header("Location: dashboard.php");
        }
        else {
            header("Location: admin.php");
        }
    }
    else {
        echo "<script>alert('Already Issued')</script>";
    }
}
elseif (isset($_POST['cancel_verify'])) {
    $var_id = $_POST['id'];
    $status_check = "SELECT verified FROM student WHERE id = '$var_id' LIMIT 1";
    $s_check = $db->query($status_check);
    $s_value = $row = $s_check->fetch_assoc();
    if ($s_value['verified'] == "1") {
        $sql_update_status = "UPDATE student SET verified = 0 WHERE id='$var_id' ";
        $db->query($sql_update_status);
    }

    if ($_SESSION['dashboard'] == "true") {
    header("Location: dashboard.php");
    }
    else {
    header("Location: admin.php");
    }
}
} // requested Method call
else {
header("Location:login.html");
}
?>

由于我是Ajax的新手，所以我很困惑在哪里插入javascript和ajax。我想要的是将表行中的文本从“未发行”更改为“已发行”，或在删除时淡出。我试图遵循一些教程，但是它们非常令人困惑

我还想要一个按钮，它将ajax显示的所有记录从“未发行”更新为“发行”状态。

使用ajax更新动态生成的表行
