我正在使用angularjs，其中包含来自ng重复的一些数据以及一个用于过滤值的输入文本框，带有div的数据是可折叠的，但是当我将任何内容过滤到与折叠div相关的数据的文本框中时，已经折叠的框不会扩展。这是下面的代码，也是在 plunker 中https://plnkr.co/edit/z4SWv6n1mfH5E4SizOPr?p=preview

脚本.js
angular.module('app', ['ui.bootstrap','ngSanitize','angular.filter']);
angular.module('app').controller('AccordionDemoCtrl', function ($scope) {
$scope.oneAtATime = true;
$scope.open = function (index) {
$scope.groups[index].isOpen = !$scope.groups[index].isOpen;
$scope.closeOthers(index);
}
$scope.closeOthers = function (index) {
for(var i = 0; i < $scope.groups.length; i++) {
if (i !== index)
$scope.groups[i].isOpen = false;
}
}
$scope.groups[0].isOpen = true;
$scope.groups = [
{
title: 'title 1',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a']
},
{
title: 'title 2',
list: ['item1b',
'<b>item2b </b> blah ',
'item3b']
},
{
title: 'title 3',
},
{
title: 'title 4',
},
{
title: 'title 5',
}
];
});
使用筛选器时，不要使用索引来更新数组
试试这个，在这里我将该项目作为过滤器传递，以便我们可以知道哪个节点被要求折叠或展开。 您也可以使用 id 来过滤数组。
<div>
<input type="text" ng-model="item.value">
<div ng-repeat="group in groups | filter:item.value">
<div class="parents" ng-click="open(group)"><i ng-class="{'glyphicon-minus': group.isOpen, 'glyphicon-plus': !group.isOpen}"></i> {{ group.title }}
</div>
{{ group.content }}
<ul class="childs" ng-show="group.isOpen">
<li ng-repeat="item in group.list">
<span ng-bind-html="item"></span>
</li>
</ul>
</div>
</div>
和您的控制器，我们正在使用该项目来过滤掉它。
$scope.open = function (item) {
$scope.groups.filter(a=> a ===item).forEach(a=>{
a.isOpen = !a.isOpen;
});
$scope.closeOthers(item);
}
$scope.closeOthers = function (item) {
$scope.groups.filter(a=> a !==item).forEach(a=>{
a.isOpen = false;
});
}
