Firebug Double console.log消息

Question

我正在創建一個類來創建和刪除文件夾以及其他一些我仍然需要處理的事情。我通過ajax來做這件事。它工作正常。但是我在控制檯中得到了同樣的信息兩次。

這是爲什麼？難道我做錯了什麼？

這裏是我的代碼至今（也可在http://snippi.com/s/3sfsfvm）：

<?php 

//process.php 

if(!empty($_POST['foldddername'])) { 

    require_once 'test.php'; 
    $folder = new folder; 

    $path = dirname(__FILE__); 

    $foldername = strip_tags($_POST['foldddername']); 

// $folder ->crtFolder($foldername,$path); 
    if($message = $folder ->crtFolder($foldername,$path)) { 
     echo $message; 
    } 
} 


?> 

    <?php 

//test.php 

class folder 
{ 

    public function crtFolder($foldername,$path){ 
     $dirpath = $path."\\".$foldername; 

     if ((!is_dir($dirpath))) { 
      if(mkdir($dirpath,0777,true)) { 
       $error = false; 
       $message['error'] = false; 
       $message['message'] = "Folder Created"; 
       return json_encode($message); 
      } 
       else { 
        $error = true; 
        $message['error'] = true; 
        $message['message'] = "Folder Failed To Create"; 
        return json_encode($message); 
       } 
     } 
      else { 
       $error = true; 
       $message['error'] = true; 
       $message['message'] = "Folder Already Exists"; 
       return json_encode($message); 
      } 

    } 
} 


?> 



    //Ajax handling 

$(function(){ 
$('.submittt').click(function(){ 
     if($('input.folder-name').val() == "") 
     { 
      console.log('Please enter Folder Name'); 
      return false; 
     } 
     else 
     {   
      $.ajax 
      ({ 
       type: 'POST', 
       url: 'process.php', 
       dataType: 'json', 
       data: 
       { 
        foldddername: $('input.folder-name').val() 
       }, 
       success:function(data) 
       { 
        console.log(data.message); 
        if(data.error === true) 
        { 
         console.log(data.message); 
        } 
        else 
        { 

         console.log(data.message); 

        } 
       }, 
       error:function(XMLHttpRequest,textStatus,errorThrown) 
       { 
        console.log(data.message); 
       } 
      }); 
      return false; 
     } 
    }); 

});

這部分代碼會產生重​​復：

success:function(data) { 
    console.log(data.message); # 1st time 
    if(data.error === true) { 
    console.log(data.message); # duplicate 
} 
else { 
    console.log(data.message); # duplicate 
    } 
},
