我正在尝试使用PhoneGap插件扫描条形码并卡在中间。
问题似乎与index.html中的window.plugins.barcodeScanner.scan有关。不知道如何解决它。
<script type="text/javascript" src="cordova-2.2.0.js"></script>
<script type="text/javascript" src="barcodescanner.js"></script>
<script type="text/javascript">
function scanCode(){
window.plugins.barcodeScanner.scan(
function(result){
alert("Scanned Code: " + result.text
+ ". Format: " + result.format
+ ". Cancelled: " + result.cancelled);
},
function(error){
alert("Scan failed: " + error);
}
);
}
function encodeData(){
var data = document.getElementById("data").value;
if (data != ''){
window.plugins.barcodeScanner.encode(
BarcodeScanner.Encode.TEXT_TYPE, data,
function(success){
alert("Encode success: " + success);
},
function(fail){
alert("Encoding failed: " + fail);
}
);
}
else{
alert("Please enter some data.");
return false;
}
}
</script>
</head>
<body>
<h3>Barcode/QR Code Scanner And Encoder</h3>
<input type="button" value="Scan Code" onclick="scanCode();"/><br/><br/>
Data : <br/>
<input type="text" name="data" id="data" /><br/><br/>
<input type="button" value="Encode Data" onclick="encodeData();"/>
</body>
