I have a server app that returns an xls file, and from javascript I make the POST call, so that when I return the file, hide the gif of "loading ..." and allow the browser to download the file. If I do $ ("#respuestas_form") .submit (); it works perfect, but I can not hide the gif of "loading ..." So I used the following but it does not work for me:
$.ajax({
type: 'POST',
url: $('#respuestas_form').attr('action'),
data: {
'csrfmiddlewaretoken': '{{ csrf_token }}',
'encuesta_id': $( "#encuesta_id" ).val(),
},
success: function(result){
$("#div_cargando").hide();
$( "#errors" ).html("");
var contentType = "application/ms-excel";
var filename = "marcelo.xlsx"
//var attachment = "attachment";
//var blob = new Blob([result], { type: contentType, Content-Disposition: attachment });
return new File([result], filename, {type: contentType, lastModified: Date.now()});
//window.open(filename);
}
});How should I do so that the browser allows me to download the file?
