Phonegap條碼掃描器：無法運行

Question

我試圖創建一個默認的Phonegap條碼掃描器槽插件基本安裝，但它不能正常工作。我不知道發生了什麼事。這裏是我的代碼：

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); 
    console.log('-'); 
    console.log(cordova); 
    console.log('-'); 
    console.log(cordova.plugins.barcodeScanner); 
    console.log('-'); 
    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); 
     } 
    ); 
    } 
}; 

它基本上是默認的Phonegap插件面板。問題是它不承認cordova.plugin.barcodeScanner。我通過Phonegap Windows工具創建了該項目，並在該文件夾中運行了cordova plugin add cordova-plugin-statusbar命令。請幫助我，我看不到這個工作的任何代碼示例。謝謝。

你可以調用getScanner（）函數onClick事件在JavaScript Read More Here

function getScanner(){ 
    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); 
     } 
    ); } 

讓我知道，如果它不工作..
