使用 uib-accordion 的条件标题颜色

Question

我在我的 angularjs 应用程序中使用 angular-ui。我的页面上有一个手风琴 (uib-accordion) 元素。它的内容、名称和状态（打开/关闭）绑定到控制器中的数组。

我想实现以下行为：当标签关闭时，标题应该是灰色的。当它打开时，它应该是另一种颜色。根据 filter.isOpened 的值，我该怎么做？我尝试使用 ng-class 类似的东西：

 ng-class="{'panel-blue-heading': filter.isOpened}"

但我没能做到。下面是一个简单的小提琴，也许它有帮助。 谢谢！

var app = angular.module("myApp", ['ui.bootstrap']);
app.controller('testCtrl', ['$scope', function($scope) {
  $scope.filtersInfo = [{
    filterParams: [1, 2, 3, 4],
    filterName: "testFilter",
    isOpened: true
  }];
}]);

.panel-default {
  border: 0;
}

.panel-group {
  margin-bottom: 5px;
}

.panel-body {
  padding: 5px;
}

.panel-default >.panel-heading {
  color: black;
}

.panel-blue-heading >.panel-heading {
  background-color: #42c6eb;
  color: black;
}

.container {
  padding: 10px;
  border-radius: 15px;
  border: 1px solid black;
}

Answer 1

你快到了：

<uib-accordion close-others="oneAtATime" ng-class="{'opened': filter.isOpened}" id="my-accordion">

然后在您的 CSS 中，定位由指令创建的 .panel-heading：

#my-accordion.opened .panel-heading {
  background-color: blue;
}

我添加 ID 是为了不影响任何其他不打算具有蓝色背景的面板标题。

var app = angular.module("myApp", ['ui.bootstrap']);
app.controller('testCtrl', ['$scope', function($scope) {
  $scope.filtersInfo = [{
    filterParams: [1, 2, 3, 4],
    filterName: "testFilter",
    isOpened: true
  }];
}]);

#my-accordion.opened .panel-heading {
  background-color: blue;
}

.panel-default {
  border: 0;
}

.panel-group {
  margin-bottom: 5px;
}

.panel-body {
  padding: 5px;
}

.panel-default >.panel-heading {
  color: black;
}

.panel-blue-heading >.panel-heading {
  background-color: #42c6eb;
  color: black;
}

.container {
  padding: 10px;
  border-radius: 15px;
  border: 1px solid black;
}
