jquery - Uploading a zip file using POST in Javascript fails silently -


i working on web application (using jquery version 2.2.4) allows users submit images , data our server. when users decide upload submissions, code should generate zip file using jszip library , upload our server using post. after searching here on stackexchange, came code:

var zip = new jszip();   // create object representing zip file  // ...add data , images  console.log('generating compressed archive...'); zip.generateasync({     compression: 'deflate',     type: 'blob' }).then(function(zc) {// function called when generation complete     console.log('compression complete!');     // create file object upload     var fileobj = new file([zc], filename);     console.log('file object created:', fileobj);     $.post('http://myurl/submit', {     data: fileobj,     }).done(function() {         console.log('ajax post successful.');     })     .fail(function(jqxhr, textstatus, errorthrown) {         console.log('ajax post failed. status:', textstatus);         console.log(errorthrown);     }); });

my code prints file object created message, file object looks ok, nothing else. silent failure. post call not appear in net panel firebug.

after more searching, tried add code beforehand:

$(document).ajaxerror(function(event, jqxhr, settings, thrownerror) {     console.log('ajax post failed. event:', event);     console.log('ajax settings:', settings);     console.log(thrownerror); });

but doesn't triggered. there's error making in setting callbacks errors - try?

i think don't see post because data object doesn't contain string values (i post if use {data: "content"}).

following https://stackoverflow.com/a/19015673 , https://stackoverflow.com/a/18254775, need add parameters (documentation):

$.post({   url: "/test",   data: fileobj,   contenttype: false,   processdata: false })
