Question

i am looking for solution to hide (just not print) menu items if the page content is empty.

by default wordpress create menu item when new page created. and that ok.

but what i don't want, is when new page created, and the user still did not add any content to the page, is to show the page in the menu.

You could try this, loop through all the wp_nav_menu items, get the post using the Object ID then test to see IF the content is empty. IF that content is empty then unset it from the items array:

function remove_empty_items( $items ) {
    $blog_page = get_option( 'page_for_posts' );
    $home_page = get_option( 'page_on_front' );
    $postArr   = get_posts ( 'post_type=post' );

    foreach( $items as $key => $item ) {
        $tmpPost = get_post( $item->object_id );

        if( $item->object_id == $blog_page && empty( $postArr ) ) {
            unset( $items[$key] );
        } else if( $item->object_id !== $home_page && empty( $tmpPost->post_content ) ) {
            unset( $items[$key] );
        }
    }

    return $items;
}
add_filter( 'wp_get_nav_menu_items', 'remove_empty_items' );
