我只是测试它并且工作正常：
I just tested it and works fine :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="msapplication-tap-highlight" content="no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
<link rel="stylesheet" type="text/css" href="css/index.css" />
</head>
<body>
<button onclick="scanBarcode()">Scan</button>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/index.js"></script>
<script>
function scanBarcode(){
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);
}
);
}
</script>
</body>
</html>
您的代码的问题是，您没有scan（）和encode绑定到您的按钮，因此什么也不会发生。
The issue with your code is that you don't have functions scan() and encode() to bind to your buttons thus nothing will happen.
