Firebug Double console.log消息

Question

我正在创建一个类来创建和删除文件夹以及其他一些我仍然需要处理的事情。我通过ajax来做这件事。它工作正常。但是我在控制台中得到了同样的信息两次。

这是为什么？难道我做错了什么？

这里是我的代码至今（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; 
     } 
    }); 

});

这部分代码会产生重​​复：

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