如果我有这段代码：
<accordion-group heading="{{group.title}}" ng-repeat="group in groups">
{{group.content}}
</accordion-group>
使用AngularJS，angular-ui和Twitter Bootstrap，可以在打开时让手风琴调用一些动作吗？我知道我不能简单地添加ng-click，因为在将其“编译”为HTML以打开/折叠该组之后就已经使用了它。

手风琴组还允许使用accordion-heading指令，而不是将其作为属性提供。您可以使用它，然后使用ng-click将标题包装在另一个标记中。
<accordion-group ng-repeat="group in groups" heading="{{group.title}}" is-open="group.open">
<accordion-heading>
<span ng-click="opened(group, $index)">{{group.content}}</span>
</accordion-heading>
</accordion-group>

以下是基于 pkozlowski.opensource 解决方案的解决方案。
您可以使用动态定义的属性，而不是在集合的每个项目上添加 $ watch 。在这里，您可以将组的 IsOpened 属性绑定到 is-open 属性。
<accordion-group ng-repeat="group in groups" heading="{{group.title}}" is-open="group.IsOpened">
{{group.content}}
</accordion-group>
因此，您可以在控制器中的每个项目集上动态添加 IsOpened 属性：
$scope.groups.forEach(function(item) {
var isOpened = false;
Object.defineProperty(item, "IsOpened", {
get: function() {
return isOpened;
},
set: function(newValue) {
isOpened = newValue;
if (isOpened) {
console.log(item); // do something...
}
}
});
});
使用属性代替观看更适合演出。
答案 2 :(得分：24)
accordion-group上有is-open属性，指向可绑定表达式。当给定的手风琴组打开时，您可以观看此表达式并执行某些逻辑。使用此技术，您可以将标记更改为：
<accordion-group ng-repeat="group in groups" heading="{{group.title}}" is-open="group.open">
{{group.content}}
</accordion-group>
这样您就可以在控制器中准备所需的监视表达式：
$scope.$watch('groups[0].open', function(isOpen){
if (isOpen) {
console.log('First group was opened');
}
});

我使用了一个关联数组来创建打开状态和模型对象之间的关系。
HTML是：
<div ng-controller="CaseController as controller">
<accordion close-others="controller.model.closeOthers">
<accordion-group ng-repeat="topic in controller.model.topics track by topic.id" is-open="controller.model.opened[topic.id]">
<accordion-heading>
<h4 class="panel-title clearfix" ng-click="controller.expand(topic)">
<span class="pull-left">{{topic.title}}</span>
<span class="pull-right">Updated: {{topic.updatedDate}}</span>
</h4>
</accordion-heading>
<div class="panel-body">
<div class="btn-group margin-top-10">
<button type="button" class="btn btn-default" ng-click="controller.createComment(topic)">Add Comment<i class="fa fa-plus"></i></button>
</div>
<div class="btn-group margin-top-10">
<button type="button" class="btn btn-default" ng-click="controller.editTopic(topic)">Edit Topic<i class="fa fa-pencil-square-o"></i></button>
</div>
<h4>Topic Description</h4>
<p><strong>{{topic.description}}</strong></p>
<ul class="list-group">
<li class="list-group-item" ng-repeat="comment in topic.comments track by comment.id">
<h5>Comment by: {{comment.author}}<span class="pull-right">Updated: <span class="commentDate">{{comment.updatedDate}}</span> | <span class="commentTime">{{comment.updatedTime}}</span></span></h5>
<p>{{comment.comment}}</p>
<div class="btn-group">
<button type="button" class="btn btn-default btn-xs" ng-click="controller.editComment(topic, comment)">Edit <i class="fa fa-pencil-square-o"></i></button>
<button type="button" class="btn btn-default btn-xs" ng-click="controller.deleteComment(comment)">Delete <i class="fa fa-trash-o"></i></button>
</div>
</li>
</ul>
</div>
</accordion-group>
</accordion>
控制器代码段为：
self.model = {
closeOthers : false,
opened : new Array(),
topics : undefined
};
在AJAX调用中填充'主题'。将“已打开”状态与从服务器更新的模型对象分开意味着在刷新时保留状态。
我还用ng-controller="CaseController as controller"

这是一个受kjv答案启发的解决方案，它可以轻松跟踪哪个手风琴元素是开放的。我发现难以让ng-click使用手风琴标题，尽管在<span>标记中包含元素并将ng-click添加到工作正常。
我遇到的另一个问题是，虽然accordion元素以编程方式添加到页面中，但内容却没有。当我尝试使用链接到{{path}}变量的Angular指令（即。$scope）加载内容时，我会被undefined命中，因此使用了波纹管方法来填充手风琴内容使用嵌入在其中的ID div。
<强>控制器：
//initialise the open state to false
$scope.routeDescriptors[index].openState == false
function opened(index)
{
//we need to track what state the accordion is in
if ($scope.routeDescriptors[index].openState == true){ //close an accordion
$scope.routeDescriptors[index].openState == false
} else { //open an accordion
//if the user clicks on another accordion element
//then the open element will be closed, so this will handle it
if (typeof $scope.previousAccordionIndex !== 'undefined') {
$scope.routeDescriptors[$scope.previousAccordionIndex].openState = false;
}
$scope.previousAccordionIndex = index;
$scope.routeDescriptors[index].openState = true;
}
function populateDiv(id)
{
for (var x = 0; x < $scope.routeDescriptors.length; x++)
{
$("#_x" + x).html($scope.routeDescriptors[x]);
}
}
<强> HTML：
<div ng-hide="hideDescriptions" class="ng-hide" id="accordionrouteinfo" ng-click="populateDiv()">

<accordion-group ng-repeat="path in routeDescriptors track by $index">

<span ng-click="opened($index)">route {{$index}}</span>

你可以使用Angular指令：
<div uib-accordion-group is-open="property.display_detail" ng-repeat="property in properties">
<div uib-accordion-heading ng-click="property.display_detail = ! property.display_detail">
some heading text
</div>
<!-- here is the accordion body -->
<div ng-init="i=$index"> <!-- I keep track of the index of ng-repeat -->
<!-- and I call a custom directive -->
<mydirective mydirective_model="properties" mydirective_index="{% verbatim ng %}{{ i }}{% endverbatim ng %}">
here is the body
</mydirective>
</div>
</div>
app.directive("mydirective", function() {
return {
restrict: "EAC",
link: function(scope, element, attrs) {
/* note that ng converts everything to camelCase */
var model = attrs["mydirectiveModel"];
var index = attrs["mydirectiveIndex"];
var watched_name = model + "[" + index + "].display_detail"
scope.$watch(watched_name, function(is_displayed) {
if (is_displayed) {
alert("you opened something");
}
else {
alert("you closed something");
}
});
}
}
});
我的设置有一些特性（我使用Django，因此＆＃34; {％verbatim％}＆＃34;标签），但该方法应该有用。
