NFC阅读器的Apache Cordova
问题描述:
我想读NFC卡与PhoneGap的NFC(Tutorial phonegap),但该事件没有启动NFC阅读器的Apache Cordova
这是index.js
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));
}
);
},
任何建议的代码?
答
与nfc.addTagDiscoveredListener,而不是nfc.addNdefListener
解决的,你想阅读与应用程序打开?你有任何输出在控制台或警报? – Del
