Question

你能告诉我如何以角度切换行。换句话说，我做了一个简单的折叠行示例项目，当用户点击与 Accordion 相同的行时，它会扩展。所以我的问题是，当我点击第一行它打开或扩展第三行为什么？只有第一行会扩展..我们可以添加一些线性过渡，因为它看起来像向上滑动并向下滑动。

点击第一行，展开第三行为什么？

我们可以添加滑动并以慢动作滑动吗？

Answer 1

这是你想要的，或者至少是一个起始布局：

HTML：

<html ng-app="ionicApp">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
    <title>Ionic Accordion</title>

    <link href="//code.ionicframework.com/nightly/css/ionic.css" rel="stylesheet">
    <script src="//code.ionicframework.com/nightly/js/ionic.bundle.js"></script>

  </head>

  <body ng-controller="MyCtrl">

    <ion-header-bar class="bar-positive">
      <h1 class="title">Accordion List</h1>
    </ion-header-bar>

    <ion-content>

      <ion-list>
        <div ng-repeat="group in groups">
          <ion-item class="item-stable"
                    ng-click="toggleGroup(group)"
                    ng-class="{active: isGroupShown(group)}">
              <i class="icon" ng-class="isGroupShown(group) ? 'ion-minus' : 'ion-plus'"></i>
            &nbsp;
            Group {{group.name}}
          </ion-item>
          <ion-item class="item-accordion"
                    ng-repeat="item in group.items"
                    ng-show="isGroupShown(group)">
            {{item}}
          </ion-item>
        </div>
      </ion-list>

    </ion-content>

  </body>
</html>

JS：

angular.module('ionicApp', ['ionic'])

.controller('MyCtrl', function($scope) {
  $scope.groups = [];
  for (var i=0; i<10; i++) {
    $scope.groups[i] = {
      name: i,
      items: []
    };
    for (var j=0; j<3; j++) {
      $scope.groups[i].items.push(i + '-' + j);
    }
  }

  /*
   * if given group is the selected group, deselect it
   * else, select the given group
   */
  $scope.toggleGroup = function(group) {
    if ($scope.isGroupShown(group)) {
      $scope.shownGroup = null;
    } else {
      $scope.shownGroup = group;
    }
  };
  $scope.isGroupShown = function(group) {
    return $scope.shownGroup === group;
  };

});

CSS：

body {
  cursor: url('http://ionicframework.com/img/finger.png'), auto;
}

/*
 * http://docs.angularjs.org/api/ng/directive/ngShow#usage_animations
 */
.list .item.item-accordion {
  line-height: 38px;
  padding-top: 0;
  padding-bottom: 0;
  transition: 0.09s all linear;
}
.list .item.item-accordion.ng-hide {
  line-height: 0px;
}
.list .item.item-accordion.ng-hide-add,
.list .item.item-accordion.ng-hide-remove {
  display: block !important;
}

如何在角度切换行以扩展或折叠行，如同在手风琴？
