伙计们。我曾尝试用ajax构建wordpress简单的注册表单，但根本不起作用。这是我的代码，一个php和jQuery ajax。请告诉我我的代码有什么问题。

仅供参考，（1）“警报”不起作用，（2）数据没有输入到我的自定义表中，（3）我在“我的测试注册表”中添加了“e.preventDefault（）”和“return false”。但当我重新加载浏览器时，它并没有避免重新加载表单。

// The .php function code

if (!defined(\'ABSPATH\')) { exit; }
add_action( \'wp_enqueue_scripts\', \'load_scripts\' );

// Load scripts
function load_scripts()
{
    // I called jquery.min.js and jquery validation from function.php, not from here

    wp_enqueue_script(\'test-reg\', get_template_directory_uri() . \'/js/my-test-reg.js\', array(\'jquery\'), \'1.0\', true ); 

    wp_localize_script( \'test-reg\', \'myAjax\', array(
        \'myUrl\' => admin_url(\'admin-ajax.php\')
        ) 
    );

    add_action( \'wp_ajax_nopriv_add_to_register\', \'to_register\' );
}

function to_register()
{
    $nonce = $_REQUEST[\'nonce\'];

    if ( empty( $_POST) || !wp_verify_nonce( $nonce, \'my-nonce\') )
    {
        die(\'Oopss...\');
    } else {
        global $wpdb;

        $firstName = sanitize_text_field( $_POST[\'firstName)\'] );
        $lastName  = sanitize_text_field( $_POST[\'lastName)\'] );
        $email     = sanitize_email( $_POST[\'email\'] );

        $custom_table = $wpdb->prefix . "my_custom_table";
        $the_email = $wpdb->get_row( "SELECT `email` FROM $table_name" );

        if ( $the_email == $email )
        {
            $res[\'type\'] = \'error\';
            $res[\'show\'] = \'<span> The e-mail you entered already exists</span>\';

            $res = json_encode($res);
            echo $res;

            die();
        } else {
            $entered = $wpdb->insert ($custom_table, 
                array(
                    \'firstName\' => $firstName,

                    \'email\' => $email

                    \'%s\', 
                    \'%s\'
                ) 
            );

jQuery(document).ready(function($) {

                if ( response.type == \'success\' )
                {
                    alert( \'Congrat, you are success!\' ); // Doesn\'t work
                    $( \'#response\' ).html();  // Doesn\'t work
                } else {
                    alert( \'Not Success!\' );  // Doesn\'t work
                    $( \'#response\' ).html();  // Doesn\'t work
                }
            }
