MozNDEFRecord.id

The id property of the MozNDEFRecord interface is application dependent (an appropriate id can be used, depending on functionality), but generally will return an NDEF Record identifier. 

Syntax

readonly attribute Uint8Array id;

Example

var tnf     = 0x1;                                                    // NFC Forum Well Known type
var type    = new Uint8Array(NfcUtils.fromUTF8("U"));                 // URL type
var id      = new Uint8Array(NfcUtils.fromUTF8(""));                  // id
var payload = new Uint8Array(NfcUtils.fromUTF8("\u0003mozilla.org")); // URL data, with a short record prefix 0x3 replacing http://

var ndefRecords = [new MozNDEFRecord(tnf, type, id, payload)];
