Question

使用以下参考资料：

点击其他标签时，我试图在离子应用中停止播放视频。

为了解决这个问题，我尝试了两种方法：

1）包含了像ionic.bundle.js这样的jquery：

<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();

但这会产生错误：

TypeError：$（...）。pause不是函数

我使用的另一种方法是：

2） angular.element(document.getElementById("compass")).pause();

但是我收到了这个错误：

TypeError：angular.element（...）。pause不是函数

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！

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...
    }
});

＆＃13;

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