这就是我在自定义BuddyPress主题中使用默认BP ajax查询/脚本的方式：

（带代码的要点：https://gist.github.com/3154297 )

function bp_custom_include_ajax() {
  global $bp;
  require_once( BP_PLUGIN_DIR . \'/bp-themes/bp-default/_inc/ajax.php\' );
    if ( !is_admin() ) {
    // Register buttons for the relevant component templates
    // Messages button
    if ( bp_is_active( \'messages\' ) )
      add_action( \'bp_member_header_actions\',    \'bp_send_private_message_button\' );
  }
      // Group buttons
    if ( bp_is_active( \'groups\' ) ) {
      add_action( \'bp_group_header_actions\',     \'bp_group_join_button\' );
      add_action( \'bp_group_header_actions\',     \'bp_group_new_topic_button\' );
      add_action( \'bp_directory_groups_actions\', \'bp_group_join_button\' );
    }
}
add_action( \'after_setup_theme\', \'bp_custom_include_ajax\', 11 );


function bp_custom_enqueue_global_script() {

    // Add words that we need to use in JS to the end of the page so they can be translated and still used.
  $params = array(
    \'my_favs\'           => __( \'My Favorites\', \'buddypress\' ),
    \'accepted\'          => __( \'Accepted\', \'buddypress\' ),
    \'rejected\'          => __( \'Rejected\', \'buddypress\' ),
    \'show_all_comments\' => __( \'Show all comments for this thread\', \'buddypress\' ),
    \'show_all\'          => __( \'Show all\', \'buddypress\' ),
    \'comments\'          => __( \'comments\', \'buddypress\' ),
    \'close\'             => __( \'Close\', \'buddypress\' )
  );

  // Bump this when changes are made to bust cache
  $version = \'20120712\';
  $params[\'view\']     = __( \'View\', \'buddypress\' );

  // Enqueue the global JS - Ajax will not work without it
  wp_enqueue_script( \'dtheme-ajax-js\', BP_PLUGIN_URL . \'/bp-themes/bp-default/_inc/global.js\', array( \'jquery\' ), $version );

  // Localize the JS strings
  wp_localize_script( \'dtheme-ajax-js\', \'BP_DTheme\', $params );
}
add_action(\'wp_enqueue_scripts\', \'bp_custom_enqueue_global_script\');
