一次扩展多个手风琴组 [英] Expand many accordion groups at once

问题描述

我在元素的分页循环中有以下手风琴(使用 angular-ui-bootstrap):

<div class="stuff_in_the_middle"><accordion id="accordion_{{$index+((currentPage-1)*20)+1}}" close-others="false"><手风琴组>[...东西...]</accordion-group><手风琴组>[...东西...]</accordion-group><手风琴组>[...东西...]</accordion-group></手风琴><span id="toggle_{{$index+((currentPage-1)*20)+1}}" onClick="openAllGroups">切换群组</span>

我想知道如何通过单击切换链接一次展开所有accordion-group 元素.可能吗?

解决方案

您可以在手风琴组上创建自己的折叠指令.在此指令中，您可以将 isOpen 范围变量(由 angular-ui 创建)设置为来自父控制器和全部切换按钮的值.

此处的工作演示 (http://plnkr.co/edit/JOOZek2QBSmxIj2pXCkK?p=preview)

js

.controller('MyCtrl', ['$scope', function($scope) {$scope.opened = false;}]).directive('collapseall', [function() {返回 {限制:'A'，范围: {崩溃:'='},链接:功能(范围，元素，属性){scope.$watch('collapseall', function(newval, oldval) {scope.isOpen = newval;})}}}])

html

<accordion close-others="false"><accordion-group Heading="Item 001" collapseall="opened"></accordion-group><accordion-group Heading="Item 002" collapseall="opened"></accordion-group><accordion-group Heading="Item 003" collapseall="opened"></accordion-group></手风琴><button class="btn" ng-click="opened=!opened">切换组</button>

I have the following accordion (using angular-ui-bootstrap) inside a paginated loop of elements:

<div data-ng-repeat="m in results">
    <div class="stuff_in_the_middle">
        <accordion id="accordion_{{$index+((currentPage-1)*20)+1}}"  close-others="false">
            <accordion-group>
                [...stuff...]
            </accordion-group>
            <accordion-group>
                [...stuff...]
            </accordion-group>
            <accordion-group>
                [...stuff...]
            </accordion-group>
        </accordion>
        <span id="toggle_{{$index+((currentPage-1)*20)+1}}" onClick="openAllGroups">Toggle groups</span>
    </div>
</div>

I would like to know how to expand all accordion-group elements at once with one click of the Toggle link. Is it possible?

解决方案

You could create your own collapseall directive on the accordion-groups. In this directive you can set the isOpen scope variable (created by angular-ui) to the value from your parent controller and your toggle all button.

EDIT: working demo here (http://plnkr.co/edit/JOOZek2QBSmxIj2pXCkK?p=preview)

js

.controller('MyCtrl', ['$scope', function($scope) {
    $scope.opened = false;
}])

.directive('collapseall', [function() {
    return {
      restrict: 'A',
      scope: {
        collapseall: '='
      },
      link: function(scope, elem, attrs) {
        scope.$watch('collapseall', function(newval, oldval) {
          scope.isOpen = newval;
        })
      }
    }
  }
])

html

<div>
    <accordion close-others="false">
        <accordion-group heading="Item 001" collapseall="opened"> 
        </accordion-group>
        <accordion-group heading="Item 002" collapseall="opened">
        </accordion-group>
        <accordion-group heading="Item 003" collapseall="opened">
        </accordion-group>
    </accordion>
    <button class="btn" ng-click="opened=!opened">Toggle groups</button>
</div>
