MozNFC.onpeerready

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

JavaScript
attribute EventHandler onpeerready;

Example

js;highlight[9,10,11,12,13,14,15,16,17,18]
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 http://
 
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!");
  };
};
