问题描述

我有以下观点:

 <ion-view ng-controller="recentDetailCtrl as vm">
   <ion-content  class="has-header">
      <div  style="padding:0px;">
        <my-video  video-url='vm.videoUrl'
           player-width="'100%'" player-height="'180px'"></my-video> 
    </div>
    <ion-scroll>
      <ion-list>
        <ion-item ng-repeat="comment in vm.comments">
                {{comment.text}}

        </ion-item>
      </ion-list>
   </ion-scroll>
  </ion-content>
</ion-view>

我想要的是我要滚动的评论列表,但始终固定视频元素(因此它保持不变在视频下方滚动 - 类似于移动youtube应用程序允许您滚动评论并修复播放视频的方式。

What I want is my list of comments to scroll but always have the video element fixed (so it stays scrolling below the video - similar to they way the mobile youtube app allows you scroll comments with the playing video fixed).

目前,当我滚动时,视频会被移出视野。

Currently when I scroll the video is moved up out of view.

推荐答案


  1. 将您的视频指令移出离子内容(离子内容中的所有元素都将滚动)。

  2. 更改离子含量的CSS它不会占据屏幕的上半部分。

  3. 位置:固定和其他css添加到您的视频指令中,以便占据屏幕的上半部分。

  1. Move your video directive out of ion-content (all elements in ion-content will be scrolled).
  2. Change the css of ion-content so that it does not occupy the upper half of the screen.
  3. Add position:fixed and other css to your video directive, so that it takes up the upper half of your screen.

      </ion-list> 
    </ion-content>

  </body>
</html>



CSS:



CSS:

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

.fixed-header{
  margin-top:43px;
  /* 
   The ionic header bar is 43px in height,
   put your content below the header bar.
  */
}

.platform-webview.platform-ios.platform-cordova .fixed-header{
  margin-top:63px;
  /* On iOS, moving a div out of ion-content,
  I think you need to compensation for the 20px system status bar.
  so it's 43px+20px=63px. but I'm not so sure, it hasn't been tested.
  Test it yourself and make modifications if needed.
  */
}

.my-video
{
  height:200px;
  width:100%;
  position:absolute;
  background:grey;
  color:red;
  text-align:center;
  padding:20px;
}

.ion-content-below-my-video{
  margin-top:200px!important;
}

.platform-webview.platform-ios.platform-cordova .ion-content-below-my-video{
  margin-top:220px;
  /*
  Same as .fixed-header
  */
}
