嵌套指令 - 无法通过Angularjs中的子指令将args传递给控制器​​方法

Question

我在angularjs中使用嵌套指令时遇到了一些麻烦.我想从另一个指令中的指令调用一个控制器方法,并试图将参数传递给它,但它们是未定义的.

我试图用下面的selected.html中的三个参数调用remove().它在我引入父指令之前工作(televisionFilter.js)任何人都可以建议如何将这些指令传递给控制器​​？

谢谢!

码:

controller.js

$scope.remove = function(selectorToRemove, choicesArr, selectedArr){
 console.log(selectorToRemove); //undefined
 console.log(choicesArr); //undefined
 console.log(selectedArr); //undefined
};

televisionFilter.js

angular.module('app.directives').directive('televisionFilter', function(){
  return{
    restrict: 'A',
    templateUrl: 'js/templates/television-filter.html',
    scope: {
      search: '=',
      selectedBrand: '=',
      submit: '&',
      remove: '&'
    }
  };
});

selected.js

angular.module('app.directives').directive('selected', function(){
  return{
    restrict: 'A',
    templateUrl: 'js/templates/selected.html',
    scope:{
    choicesArr: '=',
    selectedArr: '=',
    remove: '&'
  } 
  };
});

list.html

<div television-filter search='televisionSearch' submit="submit()" selected-brand='selectedBrand' remove='remove(selectorToRemove, choicesArr, selectedArr)'></div>

电视filter.html

<div selected selected-arr='search.selectedBrands' choices-arr='search.brands' remove='remove(selectorToRemove, choicesArr, selectedArr)'>

selected.html

<ul>
  <li ng-repeat="selected in selectedArr" class="filter-autocomplete-list"  ng-click="remove({selectorToRemove:selected, choicesArr:choicesArr,selectedArr:selectedArr})">
  <span class="label label-default label-text">{{selected}}</span> 
  </li>
</ul>

Answer 1

@charlietfl 和 @angular_james 在评论中提出的答案虽然有效，但表现出糟糕的角度实践。调用 $parent 违反了隔离范围 (&) 的要点。要使其正常工作，您只需修改中间指令（television-filter.html），如下所示：

<div selected selected-arr='search.selectedBrands' choices-arr='search.brands' remove='remove({selectorToRemove: selectorToRemove, choicesArr: choicesArr, selectedArr: selectedArr})'>
