This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The RTCDataChannel.onbufferedamountlow
property is an EventHandler
which specifies a function the browser calls when the bufferedamountlow
event is sent to the RTCDataChannel
. This event, which is represented by a simple Event
object, is sent when the amount of data buffered to be sent falls to or below the threshold specified by the channel's bufferedAmountLowThreshold
.
See "Buffering" in Using WebRTC data channels to learn more about how to work with the data channel buffer.
Syntax
RTCDataChannel.onbufferedamountlow = function;
Value
A function which the browser will call to handle the bufferedamountlow
event. This function receives as its only input parameter a simple Event
object representing the event which has occurred.
Example
This example responds to the bufferedamountlow
event by fetching up to 64kB of a file represented by an object source
and calling RTCDataChannel.send()
to queue up the retrieved data for sending on the data channel.
pc = new RTCPeerConnection(); dc = pc.createDataChannel("SendFile"); /* ... */ pc.onbufferedamountlow = function() { if (source.position <= source.length) { dc.send(source.readFile(65536)); } }
