[英]NFC reader apache cordova
I want to read nfc card with phonegap nfc ( Tutorial phonegap ) but the event is not launched 我想用phonegap nfc( 教程phonegap )读取nfc卡,但该事件未启动
this is the code of the index.js 这是index.js的代码
onDeviceReady: function() {
app.receivedEvent('deviceready');
// Read NDEF formatted NFC Tags
nfc.addNdefListener (
function (nfcEvent) {
var tag = nfcEvent.tag,
ndefMessage = tag.ndefMessage;
// dump the raw json of the message
// note: real code will need to decode
// the payload from each record
alert(JSON.stringify(ndefMessage));
// assuming the first record in the message has
// a payload that can be converted to a string.
alert(nfc.bytesToString(ndefMessage[0].payload).substring(3));
},
function () { // success callback
alert("Waiting for NDEF tag");
},
function (error) { // error callback
alert("Error adding NDEF listener " + JSON.stringify(error));
}
);
},
Any suggestion ? 有什么建议吗?
使用nfc.addTagDiscoveredListener而不是nfc.addNdefListener解决
