javascript - Convert blob to file

Question

I need to convert a blob to file i javascript.

Im using File API

var blob = new Blob(byteArrays, { type: contentType });

This is return from a function reading a cropped images.

The old upload function are using $files as input.

I want to convert that blob to file, and then set the name and type in that object. How do I do this??

Answer 1

It's easy:

var blob = new Blob(byteArrays, { type: contentType });
var file = new File([blob], filename, {type: contentType, lastModified: Date.now()});

or just:

var file = new File([byteArrays], filename, {type: contentType, lastModified: Date.now()});

The code works in Chrome and Firefox, but not IE.
