使用服务，我们可以通过设置和获取来使用变量。在控制器的注入参数中注入此服务
<body class="nav-md" ng-app="OptometristModule">
<div class="container body" ng-controller="OptometristController">
<div ng-controller="ChildController">
<input type="file" id="i_file" name="file" ng-file-select="onFileSelect($files)" multiple />
</div>
angular.module('appOptometrist')
.service('common', [function() {
this.criteria = {};
this.setCriteria = function(criteria) {
this.criteria = criteria;
};
this.getCriteria = function() {
this.criteria.limit = 1;
return this.criteria;
};
}]);
如果您需要使用服务将数据从一个控制器传递到另一个控制器，那么具有父/子关系的事件实际上在子控制器到父控制器之间就足够了，而不是从
$rootScope$emit appOptometrist.controller('ChildController', function($scope, $http, $upload) {
$scope.$emit('criteria');
:
}
appOptometrist.controller('OptometristController', function($scope, $http) {
$scope.$on('criteria', function() {:
});
});
