angularjs – angular-ui-bootstrap手风琴折叠/展开全部

我想为一组手风琴创建一个collpase / expand all按钮.我正在使用angular.js v1.2.6和angular-bootstrap-ui 0.9.0.我无法找到如何进行collpase / expand all的示例.我是一个有角度的新手,任何建议或意见表示赞赏.

另外,我应该补充一点,this post中的解决方案在我使用的较新版本的angular.js(v1.0.8 vs v1.2.6)中不起作用(这是此发布时的最新版本).在较新的版本中,它会抛出有关尝试创建两个隔离范围的错误.

标记：

<div ng-controller="myCtlr">

     <accordion close-others="oneAtATime">

     <button class="btn" ng-click="section.isCollapsed = !section.isCollapsed">Toggle Sections</button>

      <accordion-group ng-repeat="section in sections" is-open="section.isOpen">
       <accordion-heading>
        <div class="accordion-heading-content" ng:class="{Collapsed: section.isOpen}">
          {{section.namE}}
        </div>
       </accordion-heading>
        Section content
      </accordion-group>

     </accordion>

   </div>

JS：

var theapp = angular.module('myApp',[
  'ui.bootstrap'
])

function myCtlr ($scopE) {
 $scope.isCollapsed = false;
 $scope.sections = [
    {'id': '353','otherid': '7','name': 'One','Sequence': '1'},{'id': '354','otherid': '8','name': 'Two',{'id': '355','otherid': '9','name': 'Three','Sequence': '1'}
];

}
