phpexcel使用ajax返回空白excel文件

我創建了一個在Excel中打印報告的phpexcel腳本。測試代碼沒問題，但是當我在表單中爲onclick事件添加了一些ajax時，它返回空白的excel文件。這是我的phpexcel代碼：phpexcel使用ajax返回空白excel文件

include($_SERVER['DOCUMENT_ROOT']."/excel/Classes/PHPExcel.php");

$dept = $_POST['dept']; 
$from = date("Y-m-d",strtotime($_POST['from'])); 
$to = date("Y-m-d",strtotime($_POST['to'])); 

try{ 
$query = $con->prepare("SELECT * FROM emptb WHERE Department = :dept ORDER BY id ASC"); 
$query->bindParam(':dept',$dept); 
$query->execute();

這裏是莫名其妙地返回空值

function myFunction() 
    { 
    var idept = $("#cmbdept[name=dept]").val(); 
    var first = $("#from[name=from]").val(); 
    var second = $("#to[name=to]").val(); 

    $.ajax({ 
    url: "printreport.php", 
    type: 'post', 
    data: {dept: idept,from: first,to: second}, 
    cache: false, 
    global: false; 
    success: function(data) 
    { 
     //alert('Report is printing'); 
     window.open('http://localhost/hrtms/printreport.php','_blank'); 
    } 
    }); 
    return false; 
    }

我覺得你叫printreport.php兩次我的AJAX功能。
在第一次調用（在ajax），這使得excel文件。
在第二個電話（在window.open），沒有參數。
這就是爲什麼返回空文件，我猜。

如何使真實文件在printreport.php和window.open創建文件的網絡路徑？

這是我通過phpexcel製作excel文件時的代碼。

$objWriter = PHPExcel_IOFactory::createWriter($xlsObj, 'Excel2007'); 
$filename = 'FILENAME_WHAT_YOU_WANT'; 
$file_full_name = 'DATA_PATH_WHAT_YOU_WANT' . '/' . $filename; 
$objWriter->save($file_full_name);

P.S我不擅長英語，如果你覺得奇怪，請原諒我。

-----追加更多-----
在PHP退貨文件路徑之後創建Excel文件

if(file_exists($file_full_name)){ 
    echo json_encode(array('error'=>false, 'export_path'=>'/temp_upload/' . $filename)); 
}else{ 
    echo json_encode(array('error'=>true, 'error_msg' => 'Export Failed')); 
}

在javascript鏈接至創建Excel文件

$.ajax({ 
    'url': '/menu/audience/exportActivity', 
    'dataType': 'json', 
    'type': 'post', 
    'data': data, 
    success: function(r){ 
     //for loading animation to hide 
     $('body').find('div.loading.all').css('display', 'none'); 
     if(!r.error){ 
      location.href = r.export_path; 
     } 
    }, 
    error: function(a, b, c){ 
     $('body').find('div.loading.all').css('display', 'none'); 
    } 
});

這是我的代碼當我編碼

我的問題是在ajax部分不在phpexcel部分，因爲我已經在我的phpexcel中的代碼。 –

我是返回創建excel文件的web路徑，並鏈接到ajax成功函數中創建的文件。如果我的回答沒有幫助，我很抱歉。 –

謝謝你的回答，但我不認爲這會對我的問題有所幫助。 –
