給你一段剛好在用的代碼參考下：

directive：

angular.module('imageupload', []).directive('myCustomer', function() {  return {    restrict: 'A',    scope: {        image: '=',        resizeMaxHeight: '@?',        resizeMaxWidth: '@?',        resizeQuality: '@?',        resizeType: '@?',        selectedfile: '&onFileSelected'
    },    link: function postLink(scope, element, attrs, ctrl) {
    }
  };
});

html

<input type="file"
       name="file"
       class="upload"
       id="inputImage2"
       accept="image/*"
       image="image2"
       resize-max-height="300"
       resize-max-width="250"
       resize-quality="0.5" on-file-selected="transferedImage(imageResult)"/>

app.directive('directveA',function(){})
    .directive('directiveB',function(){})
    .directive('directiveC',function(){        return {            require:['directiveA','directiveB']
            link:function(scope,element,attrs,ctrls){                var aCtrl=ctrls[0];                var bCtrl=ctrls[1];                //這樣就可以訪問依賴指令的控制器了
            }
        };
    });
