当我经常使用角度md选择的索引切换标签时,多个'md-tab'同时具有'md-active'类

Question

当我经常切换md-tabs时,Md-tabs正确切换,但是多个md-tab-item元素同时具有'md-active'类,所以我看不到标签的内容是活动的,因为它是重叠的通过其右侧标签的内容.

根据我的说法,在角度材质中,当我们选择一个选项卡时,角度首先取消选择上一个选项卡(隐藏页面上先前显示的内容)并显示选定的选项卡内容.在执行此过程时,角度未命中删除先前活动的选项卡的"md-active"类.

这是重现行为的小提琴.这是随机行为,同时发生并发点击.

点击"切换标签"按钮jsFiddle后,请等待1分钟

angular.module('firstApplication', ['ngMaterial']).controller('tabController', tabController);

          function tabController ($scope) {            

             $scope.boards = Array.from(Array(100).keys());

             $scope.data = {
                selectedIndex: 0,
                secondLocked:  true,
                secondLabel:   "2",
                bottom:        false

             $scope.next = function() {
                $scope.data.selectedIndex = Math.min($scope.data.selectedIndex + 1, 2) ;
             };
             $scope.previous = function() {
                $scope.data.selectedIndex = Math.max($scope.data.selectedIndex - 1, 0);

我在100毫秒内切换标签,但在我们的应用程序中,我们也在更长的时间间隔内得到此问题.我们使用socket发出板切换事件.

据我了解，您的想法是每隔 X 秒以编程方式更改选项卡，所以...

首先，使用 angularJs$interval而不是setInterval()（这是因为 setInterval() 不关心角度摘要）。
其次，您必须更新selectedIndex而不是调用click()事件...
最后，删除活动选项卡检查（我想您添加的是为了测试）

我已经更新了你的jsFiddle

控制器：

function tabController($scope, $interval) {

    $scope.boards = Array.from(Array(100).keys());
    $scope.data = {
        selectedIndex: 0
    };

    $scope.switchTabs = function() {
        var size = $scope.boards.length - 1;

        var interval = $interval(function() {
            if(size >= 0){
                $scope.data.selectedIndex = size--;
            }else{
                $interval.cancel(interval);
            }
        }, 750);
    }
}

HTML：

<md-tabs class="md-accent" md-selected="data.selectedIndex">
    <md-tab ng-repeat="board in boards">
      <md-tab-label>{{board}}</md-tab-label>
      <md-tab-body>
          Item #{{board}}<br/>
          selectedIndex = {{board}};
      </md-tab-body>
    </md-tab>
</md-tabs>
