Question

我在文件中添加了一个过滤器，现在我得到了喷射器错误，我们都非常喜欢。我正在尝试对其进行故障排除，我认为这可能与注射顺序有关。在注入它们之前，如何声明提供者/服务/等必须编译的顺序......

HTML：

<script src="js/app.js"></script>
<script src="js/directives/jokesDirective.js"></script>
<script src="js/filters/jokeFilter.js"></script>
<script src="js/providers/jokeService.js"></script>
<script src="js/controllers/mainController.js"></script>

app.js：

angular.module('jsekoApp', [ 'ui', 'ngRoute', 'ngSlider'])
  .config( ... );

mainController.js：

angular.module('jsekoApp')
  .controller('MainController', [ '$scope', 'JokeFilter', 'JokeService', function MainController($scope, JokeFilter, JokeService) {
    ...
  }]);

JokeService工作正常 jokeFilter正在抛出错误 - jokeFilter.js：

angular.module('jsekoApp')
  .filter('JokeFilter', [ '$scope', function JokeFilter($scope) {
    ...
  }]);

在主控制器中，我在服务之前声明过滤器，因为服务需要过滤器。我认为这是正确的。我还在服务之前声明了HTML中的过滤器，并在angular和其他类似的依赖项之后声明..

完全错误：

您遇到的问题是您正在尝试直接注入过滤器。请在此处查看解决方案：How to use a filter in a controller?

基本上，您无法直接注入过滤器本身，需要使用$filter。

您可以在此处找到更多信息：https://docs.angularjs.org/api/ng/service/$filter
