Because naming a variable as formData doesn't make it a formdata object. Does the following make a new integer value?

JavaScript

var integer = 'Afzaal Ahmad Zeeshan';

No. You're doing the same, what you need is to use FormData object; not a plain JavaScript object. I wrote an article that covers this topic, kindly read it, Uploading the Files – HTML5 and jQuery Way![^]

What you need is an HTML form, then you can create a new FormData object from it and upload it to server, sample,

HTML

<form method="post" id="formid">
   <!-- Controls here. -->
</form>

Then the JavaScript would be,

JavaScript

var formData = new FormData($('#formid')[0]);
$.ajax({
   url: 'path',
   data: formData,
   success: function(response) {
      // handler
   }
});

Read the article for more deeper overview of this.
