在嵌套的 UI Bootstrap 手风琴中管理范围

Question

我正在使用 UI-Bootstrap 和这个简单的手风琴菜单。我尝试嵌套它们，但无法获取嵌套元素的范围。

ng-click 也不起作用，我猜是因为它已经用于打开和关闭手风琴了。有没有办法从子元素获取父元素？

DEMO

HTML：

<div ng-controller="accCtrl">
<accordion close-others="oneAtATime">
  <accordion-group heading="Classic Accoridion (1)" is-open="$parent.step1">
    <a href="" ng-click="clasClick()">Classic Click</a>
  </accordion-group>
  <accordion-group heading="Nested Accordian (2)" is-open="$parent.step2">
    <accordion close-others="oneAtATime">
      <accordion-group heading="Test (3)" is-open="$parent.step3">
        <a href="" ng-click="nestClick()">Nested Click</a>
      </accordion-group>
    </accordion>
  </accordion-group>
</accordion>
<p>
  Step1: {{step1}}
  <br/>Step2: {{step2}}
  <br/>Step3: {{step3}}
  <br/>
  <a href="" ng-click="openTwo()">Open Two</a>
  <br/>
  <a href="" ng-click="openThree()">Open Three</a>
</p>

JS：

function accCtrl($scope, $http, $timeout) {
    $scope.oneAtATime = true;

    $scope.step1 = true;
    $scope.step2 = false;
    $scope.step3 = false;


    $scope.openTwo = function() {
        $scope.step2 = true;
    }

    $scope.openThree = function() {
        $scope.step3 = true;
    }

    $scope.clasClick = function() {
        console.log("classic clicked");
    }

    $scope.nestClick = function() {
        console.log("nested clicked");
    }
}

看起来每个手风琴指令都在创建自己的范围。有关更多详细信息，您必须在 https://github.com/angular-ui/bootstrap/blob/master/src/accordion/accordion.js 上查看手风琴的实现

要访问父级的父级，您可以像这样输入 $parent.$parent：

<accordion close-others="oneAtATime">
  <accordion-group heading="Classic Accoridion (1)" is-open="$parent.step1">
    <a href="" ng-click="clasClick()">Classic Click</a>
  </accordion-group>
  <accordion-group heading="Nested Accordian (2)" is-open="$parent.step2">
    <accordion close-others="oneAtATime">
      <accordion-group heading="Test (3)" is-open="$parent.$parent.$parent.step3">
        <a href="" ng-click="$parent.$parent.$parent.nestClick()">Nested Click</a>
      </accordion-group>
    </accordion>
  </accordion-group>
</accordion>
