Javascript - get data out of ArrayBuffer?
arraybuffer, drag-and-drop, javascript
Solution
This might change based on your answer to my comment, but if I assume that you are using a `FileReader` somewhere, you need to read it's `result` attribute in the `loaded` callback that you need to provide:
function loaded(evt) {
var datastring = evt.target.result;
// do something here
}
reader.onload = loaded; // where reader is a FileReader, FileReaderSync
Update: Ah, I see. Well then your best course of action is to follow to this duplicate:
Converting between strings and ArrayBuffers
Update2: Note that you could probably use `readAsText()` then, but I don't know if you're at liberty to do this.
Problem
I've got a drag and drop script that uses `readAsArrayBuffer()`. The length of the buffer is perfect, but I can't seem to figure out how to pull the data out of the buffer. Apparently I've got to make a DataView or an Uint8Array or something, then iterate through its `byteLength`...help! EDIT Pertinent code (there's not much of it): ``` var reader = new FileReader(); reader.onload = function(e) { // do something with e.target.result, which is an ArrayBuffer } reader.readAsArrayBuffer(someFileHandle); ```
