当点击其他选项卡时,我正试图在我的离子应用程序中停止我的视频.

为了管理这个,我尝试了两种方法：

1)包括上面的ionic.bundle.js的jquery,如下所示：

<script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"> </script>

<!-- ionic/angularjs js -->
<script src="lib/ionic/js/ionic.bundle.js"></script>

然后在我的控制器中我尝试了$(“#compass”).pause();

但这会给出错误：

TypeError: $(…).pause is not a function

我使用的另一种方法是：

2)angular.element(document.getElementById(“compass”)).pause();

但我得到这个错误：

TypeError: angular.element(…).pause is not a function

我的视频html如下：

<ion-view>
    <div class="fullscreen-player" ng-click="closeModal()">
        <video id="compass" src="media/news_compass.mp4" width="100%" class="centerme" controls="controls" autoplay></video>
    </div>
</ion-view>

请帮忙！

解决方法

您可以创建自己的指令来控制视频,如下例所示.该示例在模式中有一个按钮,可以切换视频播放,但您可以使用自己的逻辑来停止或播放视频(将control-play属性设置为false / true).

angular.module('ionicApp',['ionic'])
 
.controller('AppCtrl',function($scope,$window,$sce,$rootScope,$ionicModal){
    $scope.videoSource = $sce.trustAsResourceUrl("http://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_1mb.mp4");

    $scope.play = true;
    $scope.togglePlayer = function(e) {
      $scope.play = !$scope.play;
      console.log('togglePlayer: '+$scope.play);
    }

  $ionicModal.fromTemplateUrl('templates/modal.html',{
    scope: $scope,animation: 'slide-in-up'
  }).then(function(modal) {
    $scope.modal = modal;
  })

  $scope.openModal = function() {
    console.log("openModal");
    $scope.modal.show()
  }

  $scope.closeModal = function() {
    $scope.modal.hide();
  };

  $scope.$on('$destroy',function() {
    $scope.modal.remove();
  });

})

.directive('videoControl',function ($rootScope) {
    return function ($scope,$element,attrs) {
      
      attrs.$observe("controlPlay",function(value) {
        console.log('controlPlay: '+value);
        value = (value == 'false' ? false : true);
        if (value==false) {
          console.log('  > stop');
          $element[0].pause();
        } else {
          console.log('  > play');
          $element[0].play();
         }
      });
      
      $element[0].addEventListener("loadeddata",function () {
        console.log('loadeddata');
        $rootScope.$broadcast('videoEvent',{ type: 'loadeddata' });
      });
      $element[0].addEventListener("playing",function () {
        console.log('playing');
        $rootScope.$broadcast('videoEvent',{ type: 'playing' });
      });
      $element[0].addEventListener("ended",function () {
        console.log('ended');
        $rootScope.$broadcast('videoEvent',{ type: 'ended' });
      });
      $element[0].addEventListener("pause",function () {
        console.log('pause');
        $rootScope.$broadcast('videoEvent',{ type: 'pause' });
      });
      // and so on...
    }
});

.video{
  width: 100%;
  height: 80%;
  margin:0 auto;
}
