刪除文件不離開頁面

Question

我允許我的用戶從他們的賬戶和文件夾刪除他們自己的文件，但每當有人點擊刪除按鈕url將他帶到remove.php並離開myfiles.php和文件被刪除。

我只是想刪除文件，而無需離開下面的頁面是，我已經簽出的代碼功能，但沒有更迭：

<script> 
function loadXMLDoc() 
{ 
var xmlhttp; 
if (window.XMLHttpRequest) 
{// code for IE7+, Firefox, Chrome, Opera, Safari 
xmlhttp=new XMLHttpRequest(); 
} 
else 
    {// code for IE6, IE5 
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); 
    } 
xmlhttp.onreadystatechange=function() 
{ 
if (xmlhttp.readyState==4 && xmlhttp.status==200) 
{ 
    // use the xmlhttp.responseText however you need. 
} 
} 
xmlhttp.open("POST", "remove.php?file=$actfolder&file=$file, true); 
xmlhttp.send(); 
} 
</script>

remove.php

if(isset($_GET['file'])){

// make sure only deleting a file in files/ directory

                 } 
          } 
          closedir($directory_handle); 
      } 
} 
?> 

這個代碼是每個文件下： <a href='remove.php?file=$actfolder&file=$file' title='Delete file '$file' from the server'>Delete</a> 預先感謝

在的，你可以去remove.php回到以前的頁面，此代碼末尾：

header("Location:".$_SERVER["HTTP_REFERER"]);
