PhoneGap条形码阅读器插件不起作用

Question

几天来我一直在尝试在我的应用程序中实现条形码读取器插件，但我没有任何运气。 当按下按钮时，它只是不执行任何操作。 多数民众赞成在我的JavaScript文件

    var app = {
// Application Constructor
initialize: function() {
    this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
    document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'
onDeviceReady: function() {
    app.receivedEvent('deviceready');
},
// Update DOM on a Received Event
receivedEvent: function(id) {
    var parentElement = document.getElementById(id);
    var listeningElement = parentElement.querySelector('.listening');
    var receivedElement = parentElement.querySelector('.received');

    listeningElement.setAttribute('style', 'display:none;');
    receivedElement.setAttribute('style', 'display:block;');

    console.log('Received Event: ' + id);
},
scan: function() {
    console.log('scanning');

    var scanner = cordova.require("cordova/plugins/BarcodeScanner");

    scanner.scan( function (result) { 

        alert("We got a barcode\n" + 
        "Result: " + result.text + "\n" + 
        "Format: " + result.format + "\n" + 
        "Cancelled: " + result.cancelled);  

       console.log("Scanner result: \n" +
            "text: " + result.text + "\n" +
            "format: " + result.format + "\n" +
            "cancelled: " + result.cancelled + "\n");
        document.getElementById("info").innerHTML = result.text;
        console.log(result);
        /*
        if (args.format == "QR_CODE") {
            window.plugins.childBrowser.showWebPage(args.text, { showLocationBar: false });
        }
        */

    }, function (error) { 
        console.log("Scanning failed: ", error); 
    } );
},
    encode: function() {
    var scanner = cordova.require("cordova/plugins/BarcodeScanner");

    scanner.encode(scanner.Encode.TEXT_TYPE, "http://www.nhl.com", function(success) {
        alert("encode success: " + success);
      }, function(fail) {
        alert("encoding failed: " + fail);
      }
    );

}};

我是否必须部署应用程序，还是可以仅使用PhoneGap for iOS提供的应用程序？ 任何帮助将不胜感激。

我相信您需要将应用程序编译并安装在设备上或在模拟器中运行（假设您最好对设备进行条形码扫描，以便可以使用真实的相机）。 与iOS版PhoneGap应用程序不兼容的原因是，条形码扫描仪似乎不在您为该应用程序安装的插件列表中，这是：

<plugin name="cordova-plugin-camera" spec="~2.0.0" />
