视频在视口中自动播放流动播放器视频 [英] Auto play flowplayer video when video in viewport

问题描述

当视频在视口中时，是否有任何已知的自动播放视频的方法，我使用以下函数来确定元素何时在视口中

Is there any known way of auto playing video when video is in viewport, I use the following function to determine when an element is in viewport

var isScrolledIntoView = function(elem) {
      // get the position of the viewport
      var docViewTop = $(window).scrollTop();
      var docViewBottom = docViewTop + $(window).height();

  // get the position of the player element
      var elemTop = $(elem).offset().top;
      var elemBottom = elemTop + $(elem).height();

  // determine if the player element is in fully in the viewport
      return ((elemBottom >= docViewTop) && (elemTop <= docViewBottom)
        && (elemBottom <= docViewBottom) &&  (elemTop >= docViewTop) );
}

<script src="//releases.flowplayer.org/6.0.5/flowplayer.min.js"></script>
<link rel="stylesheet" href="//releases.flowplayer.org/6.0.5/skin/functional.css">

<div class="flowplayer" data-swf="http://releases.flowplayer.org/6.0.5/commercial/flowplayer.swf">
   <video>
      <source type="video/mp4"  src="http://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_1mb.mp4">
   </video>
</div>

我试了几个 https://flowplayer.org/docs/api.html 中解释的样本，它没有' t似乎对我有用

I tried few samples as explained at https://flowplayer.org/docs/api.html and it doesn't seems to be working for me

推荐答案

你可以使用 flowplayer（0）.play（）以播放视图。

至于当它在视野中时 - 你可以 check check 。

You can use flowplayer(0).play() in order to play the view.
As for "when it's in view" - you can check here.

var element         = $(".flowplayer");
var topOfElement    = element.offset().top;
var bottomOfElement = element.offset().top + element.outerHeight(true);
var videoPlayedOnce = false;

$(window).bind('scroll', function() {
  var scrollTopPosition   = $(window).scrollTop()+$(window).height();
  var windowScrollTop     = $(window).scrollTop()

  if (windowScrollTop > topOfElement && windowScrollTop < bottomOfElement) {
    // Element is partially visible (above viewable area)
    console.log("Element is partially visible (above viewable area)");
  } else if( windowScrollTop > bottomOfElement && windowScrollTop > topOfElement) {
    // Element is hidden (above viewable area)
    console.log("Element is hidden (above viewable area)");
  } else if( scrollTopPosition < topOfElement && scrollTopPosition < bottomOfElement) {
    // Element is hidden (below viewable area)
    console.log("Element is hidden (below viewable area)");
  } else if( scrollTopPosition < bottomOfElement && scrollTopPosition > topOfElement) {
    // Element is partially visible (below viewable area)
    console.log("Element is partially visible (below viewable area)");
  } else {
    // Element is completely visible
    console.log("Element is fully visible");
    if (!videoPlayedOnce) {
      console.log("Only if the video wasn't played already we need to play it");
      flowplayer(0).play()
      videoPlayedOnce = true;
    }
  }
});

添加了一个变量来检查我们是否已播放视频以确保我们不播放两次（在用户暂停或视频已结束之后）。

Added a variable to check if we already played the video to make sure we don't play it twice (after the user paused it or the video ended already).
