The onpeerready
event handler of the MozNFC
interface handles the peerready
event, which fires when a suitable peer (an NFC-enabled device) comes into range of the device your NFC application is running on.
Syntax
attribute EventHandler onpeerready;
Example
var tnf = 1; // NFC Forum Well Known type var type = new Uint8Array(fromUTF8("U")); // URL type var id = new Uint8Array(fromUTF8("")); // id var payload = new Uint8Array(fromUTF8("\u0003mozilla.org")); // URL data, with a record prefix 0x3 replacing https:// var ndefRecords = [new MozNDEFRecord(tnf, type, id, payload)]; var nfcdom = window.navigator.mozNfc; nfcdom.onpeerready = function(event) { var nfcPeer = event.peer; var req = nfcpeer.sendNDEF(ndefRecords); // push NDEF message to other NFC device. req.onsuccess = function(e) { console.log("Successfully pushed P2P message"); }; req.onerror = function(e) { console.log("P2P push failed!"); }; };
