Sending byte data over Websockets (JavaScript)

Question

Is it possible to send byte data (array) over Websockets or only strings?

So any ideas why ArrayBuffer doesnt work?

Thanks in advance.

The API isn't finalized, but you should be able to use an ArrayBuffer (a JavaScript typed array).

How to add 1 byte to ArrayBuffer? arr[i] = 128; puts in array "128"(0x31 0x32 0x38). arr[i].push(128); same.

What browser? arr[i] seems to work fine in Chrome 15. At any rate, as described on the JavaScript typed arrays page, you should probably be working with a view, and not the raw array. But this is really a separate issue from your original question, so you should ask a separate question if you're having trouble.

sockets.push(new WebSocket("ws://"+serverip+":"+serverport)); sendbuf[id] = new ArrayBuffer(); sendbuf[id][0] = 128; sockets[id].send(sendbuf[id]); This send "128" not 128; (Chrome)

Yes. Blob objects claim to offer this functionality, but they're only supported on a few browsers to my understanding.
