遇到問題用調試工具看一下，也可以自己寫一些日誌，看下結果:
chrome://inspect/#devices
調用攝像頭：cordova plugin add cordova-plugin-camera
根據自己的項目適配版本，調用掃一掃：cordova plugin add phonegap-plugin-barcodescanner
git上插件太新，不兼容項目，一天都沒整明白，後來丁老師告知版本問題，心累啊
index.html如下所示：
<body>
<div class="app">
<div class="line"><button id="openLabrary">按鈕</button></div>
<div class="line"><img id="myImage" style="height: 200px;"></img></div>
</div>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</body>
</html>
index.js如下所示：
var app = {
initialize: function() {
document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
},
onDeviceReady: function() {
this.receivedEvent();
},
$$: function(id) {
return document.getElementById(id);
},
receivedEvent: function() {
var getDomLabrary = this.$$('openLabrary');
var _this = this;
getDomLabrary.onclick = function() {
cordova.plugins.barcodeScanner.scan(
function (result) {
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
},
function (error) {
alert("Scanning failed: " + error);
},
{
preferFrontCamera : false, // iOS and Android
showFlipCameraButton : true, // iOS and Android
showTorchButton : true, // iOS and Android
torchOn: true, // Android, launch with the torch switched on (if available)
saveHistory: true, // Android, save scan history (default false)
prompt : "Place a barcode inside the scan area", // Android
resultDisplayDuration: 500, // Android, display scanned text for X ms. 0 suppresses it entirely, default 1500
formats : "QR_CODE,PDF_417", // default: all but PDF_417 and RSS_EXPANDED
orientation : "landscape", // Android only (portrait|landscape), default unset so it rotates with the device
disableAnimations : true, // iOS
disableSuccessBeep: false // iOS and Android
}
);
}
}
};
app.initialize();
另附加採用Framework7框架實現的頁面：
