我不知道你为什么要这么做。。。但我能想到的唯一可行的办法是：

     function prefix_block_resources(){
         if(is_admin())return;  //I can\'t imagine any scenario where blocking scripts in the admin area would be wise.
         global $wp_scripts;
         global $wp_styles;
         $wp_scripts->queue = array();
         $wp_styles->queue = array();
         return;
     }
     add_action(\'wp_head\', \'prefix_block_resources\');
