How can javascript upload a blob?

Question

I have a blob data in this structure:

Blob {type: \"audio/wav\", size: 655404, slice: function}
size: 655404
type: \"audio/wav\"
__proto__: Blob

Answer 1

Try this

var fd = new FormData();
fd.append('fname', 'test.wav');
fd.append('data', soundBlob);
$.ajax({
    type: 'POST',
    url: '/upload.php',
    data: fd,
    processData: false,
    contentType: false
}).done(function(data) {
       console.log(data);
});

You need to use the FormData API and set the jQuery.ajax's processData and contentType to false.
