Question

我正在尝试使用Ionic Framework和Cordova实现一个Camera Application，并努力理解为什么它会抛出以下错误，从而无法实例化摄像头：

      0     444468   error    Uncaught SyntaxError: Unexpected token ., http://192.168.0.10:8100/js/app.js, Line: 9
      1     444540   error    Uncaught Error: [$injector:modulerr] Failed to instantiate module starter due to:
      Error: [$injector:nomod] Module 'starter' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

遗憾的是，以下问题和答案并没有帮助我回答我的问题：

Ionic Framework / Cordova Camera

Cordova Camera - Ionic

navigator.camera.getPicture doesn’t call success callback - ionic framework - cordova

我已经参考了以下教程来完成这项工作但没有成功（有时我感到困惑）：

 })

提前感谢您的帮助！

Answer 1

Jad Salhani是对的。

我将在这里回答，即使这应该是一个评论，因为我没有足够的空间。

这里有2个选项。您可以定义要在模块中使用的变量（app.js）：

var app = angular.module('starter', ['ionic', 'ngCordova']);

并使用app变量：

app.run(function($ionicPlatform) {
   $ionicPlatform.ready(function() {
     if(window.cordova && window.cordova.plugins.Keyboard) {
       cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
     }
     if(window.StatusBar) {
       StatusBar.styleDefault();
     } 
   });
 });

app.controller('CameraCtrl', function($scope, $cordovaCamera) {
   ...
});

或删除半列：

angular.module('starter', ['ionic', 'ngCordova'])

.run(function($ionicPlatform) {
       $ionicPlatform.ready(function() {
         if(window.cordova && window.cordova.plugins.Keyboard) {
           cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
         }
         if(window.StatusBar) {
           StatusBar.styleDefault();
         } 
       });
     })

.controller('CameraCtrl', function($scope, $cordovaCamera) {
       ...
});

Answer 2

   angular.module('starter', ['ionic', 'ngCordova']);

这就是你的错误所在，那里不应该有一个分号。

其angular.module('moduleName').controller('controllerName', function(){});

Cordova相机和Ionic Framework - Controller和Index.html没有连接
