使用PluginBoilerplate 编写插件。我需要打个ajax电话。

我添加到mainplugin.php 类来注册脚本和处理ajax调用。

if ( ! class_exists( \'PoorMansNameSpaceAJAX\' ) ) {

class PoorMansNameSpaceAJAX{
    public static $instance = null;
    public $nonce = \'\';
    public $name = \'ajaxexample\';
    public static function getInstance()
    {
        null === self::$instance AND self::$instance = new self;
        return self::$instance;
    }
    public function __construct(){
        # Could as well be: wp_enqueue_scripts or login_enqueue_scripts
        add_action( \'admin_enqueue_scripts\', array( $this, \'scriptsEnqueue\' ) );
        # Logged in users:
        add_action( \'wp_loaded\', array( $this, \'scriptsRegister\' ) );
        add_action( \'admin_enqueue_scripts\', array( $this, \'scriptsLocalize\' ) );
        add_action( \'admin_init\', array( $this, \'ajaxRegister\' ) );


    }
    public function scriptsRegister( $page ){
        $file = \'page-1.js\';
        wp_register_script(
            $this->name ,
            WPBP_URLPATH . \'/app/files/js/\' . $file ,
            array(\'jquery\')
        );
    }
    public function scriptsEnqueue( $page ){

        wp_enqueue_script( $this->name );
    }

    public function ajaxRegister() {
        add_action( "wp_ajax_{$this->name}_action",  array($this, \'ajaxexample\'), \'1\' );
    }

    public function scriptsLocalize( $page ){
        wp_localize_script( $this->name, "{$this->name}Object", array(
            \'ajaxurl\'          => admin_url( \'admin-ajax.php\' ),
            \'action\'           => "{$this->name}_action"
        ) );
    }

   public function ajaxexample(){
        ob_clean();

        echo json_encode( array(
            \'success\' => true
        ) );
        wp_die();   
    }
}
}

the main issue 尽管脚本已成功注册、排队和本地化，但ajax回调函数没有执行任何操作。

ajax调用返回空响应：html页面的内容与im中的内容相同。response.success 未设防。

    ( function( $, plugin ) {
           $(document).ready( function() {

            $(\'#moreroles\').on(\'click\', function(event) {
                event.preventDefault();
                /* Act on the event */
                var data = plugin;
                $.ajax({
                    url: plugin.ajax_url,
                    data: data,
                    beforeSend : function( d ) {
                        console.log( \'Before send\', d );
                     }
                })
                .done( function( response, textStatus, jqXHR ) {
                    console.log( \'AJAX done\', textStatus, jqXHR, jqXHR.getAllResponseHeaders() );
                } )
                .fail( function( jqXHR, textStatus, errorThrown ) {
                    console.log( \'AJAX failed\', jqXHR.getAllResponseHeaders(), textStatus, errorThrown );
                } )
                .then( function( jqXHR, textStatus, errorThrown ) {
                    console.log( \'AJAX after finished\', jqXHR, textStatus, errorThrown );
                } );

            });
    } );
} )( jQuery, ajaxexampleObject || {});
