This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The read-only RTCDataChannel
property ordered
indicates whether or not the data channel guarantees in-order delivery of messages; the default is true
, which indicates that the data channel is indeed ordered. This is set when the RTCDataChannel
is created, by setting the ordered
property on the RTCDataChannelInit
object passed as RTCPeerConnection.createDataChannel()
's options
parameter.
Syntax
var ordered = aDataChannel.ordered;
A Boolean
value which is true
if in-order delivery is guaranteed and is otherwise false
.
Example
var pc = new RTCPeerConnection();
var dc = pc.createDataChannel("my channel");
if (!dc.ordered) {
// Handle unordered messaging
}
