That example is missing some code. Those two empty strings should not be empty.
There is a link on that page just above the code example to api documentation of theme_menu_tree() https://api.drupal.org/api/drupal/includes%21menu.inc/function/theme_menu_tree/7.x
On the api documentation page you can see it done correctly:
return '<ul class="menu">' . $variables['tree'] . '</ul>';

I updated that documentation page on the Drupal site for future viewers.– rjlMay 20, 2017 at 23:11

Thank!!.I already try "<ul class='myclass'>" in theme_menu_tree__menu_top_menu() but still doesn't work.– ChengMay 21, 2017 at 2:15

Do you know in fact that your function is being called? Could be a issue with function name - if you are calling this from your theme, the function name should start with 'YOUR_THEME_NAME_menu_tree...' and not 'theme_menu_tree...' Did you Clear All Caches (under Admin->Config->Performance)?– rjlMay 21, 2017 at 4:18

Thank!!Yes I clear all the cache.My theme name is "abc" so I called the function abc_menu_tree__menu_top_menu(&$variables).Does this function require to override working only for main menu.– ChengMay 21, 2017 at 4:36

Your function should only override the one menu named 'menu_top_menu' and not any other menus.– rjlMay 21, 2017 at 4:43
