Question

我花了整整一周的时间尝试每种方法，但我不断重现同样的错误。我知道ngCordova.min.js必须高于Cordova.js。但似乎什么都没有加载我的插件。我访问了ngCordova网站，他们解释说这个错误可能令人沮丧而且难以修复。这是我的文件谢谢

错误撒旦自言自语

this.deliveryService.deliveryCancel(rowInfo.branchId, rowInfo.id).subscribe(
              res => {
                var data = res.json();

你的代码有一点错误，你忘了注释$ cordovaBarScaner。

＆＃13;

.controller('scannerCtrl',['$scope','$rootScope','$cordovaBarcodeScanner', '$ionicPlatform', '$stateParams',  function($scope, $rootScope, $cordovaBarcodeScanner, $ionicPlatform,stateParams) {




      $scope.scanBarcode = function() {
        $cordovaBarcodeScanner.scan().then(function(imageData) {
            alert(imageData.text);
            console.log("Barcode Format -> " + imageData.format);
            console.log("Cancelled -> " + imageData.cancelled);
        }, function(error) {
            console.log("An error happened -> " + error);
        });
    };
    }])

＆＃13;

错误：undefined不是对象（评估＆＃39; $ cordovaBarcodeScanner.scan＆＃39;）
