$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->setTitle('TestMessages');
header('Content-Type: application/vnd.ms-excel');
header("Content-Disposition: attachment; filename=test_form_".date("Y-m-d_H:i:s").".xls");
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
When I call above code directly from the browser, the result file is downloaded. But if I make an ajax call to above code, I don't get the download prompt. I can see from console tab that the ajax call was successfully completed and a bunch of random characters is seen in the response data. I'm assuming that is the excel object.
Does anyone know how I can achieve the download excel feature using ajax? I don't want to refresh the page. When the user clicks on the "export" button, there should be an ajax call to the php file and prompt the user to download.
I reffer Passing data from PHP class to PHPExcel via AJAX but do not understand how to achieve my goal?
PHP
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
ob_start();
$objWriter->save("php://output");
$xlsData = ob_get_contents();
ob_end_clean();
$response = array(
'op' => 'ok',
'file' => "data:application/vnd.ms-excel;base64,".base64_encode($xlsData)
);
die(json_encode($response));
JS
$.ajax({
type:'POST',
url:"MY_URL.php",
data: {},
dataType:'json'
}).done(function(data){
var $a = $("<a>");
$a.attr("href",data.file);
$("body").append($a);
$a.attr("download","file.xls");
$a[0].click();
$a.remove();
});
You don't actually need Ajax.
Using javascript's window.location.replace()
if you get an url which sends a file, it will prompt to be downloaded without redirecting the browser.
If you need to post data, you can create a hidden form with the fields set up the way you need them, make sure that the "target" attribute of the form is set to "_BLANK"
, and then submit the form programatically.
For first comment below :
maybe try replacing :
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
with readfile ($file_name);
当您单击按钮时,为什么不重定向到下载excel文件的页面
I solved my issue by following way.
add target=_blank in your ajax success function like below
success: function(){
window.open('http://MY_URL','_blank' );
},
On success open new window with my_url.
