在这个答案中，我创建了两个按钮，它们在视觉上被禁用，并且在提交之前得到了无效的nonce。

<?php
/*
Plugin Name: Ajax Example
*/

add_action( \'admin_notices\', \'my_action_button\' );

define( \'MY_ACTION_NONCE\', \'my-action-\' );

function my_action_button() {
    $id   = 4321;
    $data = array(
        \'data-nonce\' => wp_create_nonce( MY_ACTION_NONCE . $id ),
        \'data-id\'    => $id,
    );
    echo get_submit_button( "Ajax Primary", \'primary large\', \'my-action-button-1\', FALSE, $data );

    $id   += 1234;
    $data = array(
        \'data-nonce\' => wp_create_nonce( MY_ACTION_NONCE . $id ),
        \'data-id\'    => $id,
    );
    echo get_submit_button( "Ajax Secundary", \'secondary\', \'my-action-button-2\', FALSE, $data );
}

add_action( \'admin_footer\', \'my_action_javascript\' ); // Write our JS below here

function my_action_javascript() {
    ?>
    <script type="text/javascript">
        jQuery(document).ready(function ($) {
            $(\'#my-action-button-1,#my-action-button-2\').click(function () {
                var $button = $(this);

                var data = {
                    \'action\': \'my_action\',
                    \'id\': $button.data(\'id\'),
                    \'nonce\': $button.data(\'nonce\')
                };
                // Give user cue not to click again
                $button.addClass(\'disabled\');
                // Invalidate the nonce
                $button.data(\'nonce\', \'invalid\');

                $.post(ajaxurl, data, function (response) {
                    alert(\'Got this from the server: \' + response);

                });
            });
        });
    </script>
    <?php
}

add_action( \'wp_ajax_my_action\', \'my_action\' );

function my_action() {
    global $wpdb; // this is how you get access to the database

    $id    = $_POST[\'id\'];
    $nonce = $_POST[\'nonce\'];
    if ( wp_verify_nonce( $nonce, MY_ACTION_NONCE . $id ) ) {
        $response = intval( $id );
        $response += 10;
        echo $response;
    } else {
        echo - 1;
    }
    wp_die(); // this is required to terminate immediately and return a proper response
}
