Question

我使用指令要求用户在模态中进行操作确认它在开发过程中就像一个魅力，但是，在缩小之后，它就被打破了这是我得到的可怕的“ $ injector：unpr ”错误：

Error: [$injector:unpr] Unknown provider: aProvider <- a
...

我认为问题是$scope和$modalInstance被重命名，不应该，但我不知道如何避免这种情况......

这是指令代码：

'use strict';
app.directive('reallyClick', ['$modal', function($modal) {
  var modalInstanceCtrl = function ($scope, $modalInstance) {
    $scope.ok = function () {
      $modalInstance.close();
    };

    $scope.cancel = function () {
      $modalInstance.dismiss('cancel');
    };
  };

  return {
    restrict: 'A',
    scope: {
      reallyClick: '&',
      item: '='
    },
    link: function (scope, element, attrs) {
      element.bind( 'click', function() {
        var message = attrs.reallyMessage || 'Are you sure?';
        var modalHtml = '<div class="modal-body">' + message + '</div>';
        modalHtml += '<div class="modal-footer"><button class="btn btn-primary" ng-click="ok()">OK</button><button class="btn btn-warning" ng-click="cancel()">Cancel</button></div>';

        var modalInstance = $modal.open({
          template: modalHtml,
          controller: modalInstanceCtrl
        });

        modalInstance.result.then(function () {
          scope.reallyClick({item:scope.item}); // raise an error : $digest already in progress
        }, function() {
          // modal dismissed
        });
      });
    }
  };
}]);

我这样使用它：

...
<td title="Delete customer">
  <button
    class="btn btn-primary glyphicon glyphicon-trash"
    really-message="Are you really sure to remove customer <i>{{customer.name}}</i> ?" really-click="deleteCustomer(customerId)"
  ></button>
</td>
...

如果它可以提供任何帮助，这些是我在构建阶段使用的模块：

'auto_install',
'clean:dist',
'favicons',
'wiredep',
'useminPrepare',
'concurrent:dist',
'autoprefixer',
'concat',
'ngmin',
'copy:dist',
'cdnify',
'cssmin',
'uglify',
'filerev',
'usemin',
'htmlmin',

这些是我在我的app中注入的模块：

var app = angular.module('smallBusinessApp', [
  'ngSanitize',
  'ngRoute',
  'firebase',
  'ui.bootstrap',
]);

还需要使用依赖注入语法创建modalInstance Controller，

'use strict';
app.directive('reallyClick', ['$modal', function($modal) {    
  return {
    restrict: 'A',
    scope: {
      reallyClick: '&',
      item: '='
    },
    link: function (scope, element, attrs) {
      element.bind( 'click', function() {
        var message = attrs.reallyMessage || 'Are you sure?';
        var modalHtml = '<div class="modal-body">' + message + '</div>';
        modalHtml += '<div class="modal-footer"><button class="btn btn-primary" ng-click="ok()">OK</button><button class="btn btn-warning" ng-click="cancel()">Cancel</button></div>';

        var modalInstance = $modal.open({
          template: modalHtml,
          controller: modalInstanceCtrl
        });

        modalInstance.result.then(function () {
          scope.reallyClick({item:scope.item}); // raise an error : $digest already in progress
        }, function() {
          // modal dismissed
        });
      });
    }
  };
}]);

ModelInstanceController：

app.controller('modalInstanceCtrl',['$scope','$modalInstance',function ($scope, $modalInstance) {
    $scope.ok = function () {
      $modalInstance.close();
    };

    $scope.cancel = function () {
      $modalInstance.dismiss('cancel');
    };
  }]);

对我来说也是一个问题，不得不将模态的控制器部分分开并像这样做，希望它有所帮助!!

我想这是你的modalInstanceCtrl。尝试不实现作为指令内的对象，但作为控制器：

app.controller('modalInstanceCtrl', [ '$scope', '$modalInstance',
function ($scope, $modalInstance) {
  $scope.ok = function () {
    $modalInstance.close();
  };

  $scope.cancel = function () {
    $modalInstance.dismiss('cancel');
  };
}]);

然后通过将其引用到引号中来引用它：

var modalInstance = $modal.open({
  template: modalHtml,
  controller: 'modalInstanceCtrl'
});
