如何在我的 php wordpress 插件中添加 AJAX

Question

I want to add AJAX in my WordPress plugin so the page doesn't have to reload entirely. I just want only the part of the page that shows this plugin to load

function trackingplugin_print_table()
{
if (!$_POST[track_number]) {
    return;
}
$url = "url here";
$code = $_POST[track_number];
$data = file_get_contents("$url$code");
$json = json_decode($data);

echo "<table class=\"table\">";
foreach ($json as $key => $row) {
    echo "<tr>";
    foreach ($row as $key0 => $row0) {
        echo "<th>" . $key0 . " : " . $row0 . "</th>";
    }
    echo "</tr>";
}
echo "</table>";
}

?>
