Create file from AJAX response data and force download - ajax

Question

I need to make an AJAX call from a page, sending some JavaScript data to a PHP file, which creates a file based on that data. I then want this file to be downloaded by the user.
So is it an option, to make a force download of a file created by PHP (specifically PHPExcel in my case) via an AJAX request?
The code shown below does not yet send any JavaScript data, but does generate a file.
This is my PHP script, which creates a file using PHPExcel:
public function renderTasksToExcel($tasksData){
$objPHPExcel = new PHPExcel();
// Set properties
$objPHPExcel->getProperties()->setCreator("TRW");
// ...
// Add some data
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'Hello');
// ...
// Rename sheet
$objPHPExcel->getActiveSheet()->setTitle('Simple');
// Save Excel 2007 file
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$file = '/export.' . date('Y-m-d-H-i-s').'.xlsx';
$objWriter->save($file);
// hotovo
return $this->sendResponse(new FileResponse($file));
}
And this is AJAX call:
$.ajax({
type: "POST",
url: {plink Tasks:tasksToExcel},
data: ajaxData,
success:function(data){
$('#download').html(data);
}
})

Answer 1

same with mine. but i already solve this problem,try this:
use this in your php:
$objWriter->save('export/FileName.xls');
and use this in your ajax call:
$.ajax({
type: "POST",
url: {plink Tasks:tasksToExcel},
data: ajaxData,
success:function(data){
$('#download').html(data);
var zz=document.createElement('a');
var data_type = 'data:application/vnd.ms-excel';
zz.href ='htp://localhost/bengkel/backend/export/FileName.xls';
zz.download='FileName'+'.xls';
zz.click();
}
})
simple concept,ajax cant download. then,save *xls file,and then download that file with JS.
