我有一个插件上的代码

 function ajaxp_init(){

    /*
    * registro del script
    */

    wp_deregister_script( \'jquery\' ); 
    wp_register_script( \'jquery\', \'http://code.jquery.com/jquery-latest.pack.js\', false, \'\' ); 

    //keep jQuery and Prototype compatible 
    $url = get_bloginfo(\'wpurl\').\'/wp-content/plugins/pablowishlist\'; 
    wp_register_script( \'jquery_no_conflict\', $url . \'/pablowishlist.js\', array( \'jquery\' ), \'\' );     
    wp_enqueue_script( \'jquery_no_conflict\' ); 

    global $post;

    wp_localize_script(\'jquery_no_conflict\',\'MyAjax\', array(
        \'postId\' => $post->ID,
        \'action\' => \'ajaxp_add_wishlist\'
    ));
    //wp_register_script( \'pablowishlist-js\', get_template_directory_uri() . \'/js/pablowishlist.js\', array( \'jquery\' ), \'2.2.1\', false );
    //wp_register_script(\'pablowishlist-js\', plugins_url(\'pablowishlist.js\',__FILE__), array(\'jquery\')); // funcion de wordpress que registra un código, javascript.

    /*
    * load script
    */
    //wp_enqueue_scripts(\'jquery\');
    //wp_enqueue_scripts(\'pablowishlist-js\');

 }

和同一目录中的JavaScript文件

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

    $(\'#ajaxp_add_wishlist\').click(function(e){
        //alert(\'hola\');
        $.post(document.location.protocol+\'//\'+document.location.host+\'/wp-admin/admin-ajax.php\', MyAjax, function(response){
            alert(response);
        });
    });
});

但是当我点击按钮时ajaxp_add_wishlist 什么都没发生。

怎么了？

add_action( \'wp_enqueue_scripts\', \'ajaxp_init\' );

     wp_enqueue_script(\'jquery\');

     wp_register_script( \'jfile_general_js\', plugins_url(\'pablowishlist.js\', __FILE__));
     wp_enqueue_script(\'jfile_general_js\')

}

/* Add shortcode

add_shortcode(\'ajaxplug\',\'jfile_manager\');
function jfile_manager() {
        global $post;

        wp_localize_script(\'jquery_no_conflict\',\'MyAjax\', array(
            \'postId\' => $post->ID,
            \'action\' => \'ajaxp_add_wishlist\'
        ));
}
