javascript - 管理嵌套 UI Bootstrap Accordion 中的范围

Question

我将 UI-Bootstrap 与这个简单的 Accordion 菜单一起使用。我试图嵌套它们，但我无法获取嵌套元素的范围。

ng-click 也不起作用，我猜是因为它已经被用来打开和关闭 Accordion 了。有没有办法从子元素到达父元素？

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 Accordion 指令都在创建自己的作用域。有关更多详细信息，您必须在 https://github.com/angular-ui/bootstrap/blob/master/src/accordion/accordion.js 查看 Accordion 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>
