Question

我在视频完成后使用视频作为背景我想将视频背景更改为颜色背景，如红绿色或任何颜色。我正在尝试HTML5但卡住了。任何人都可以帮助我。

Answer 1

试试这段代码，根据我的理解，这可能就是你要搜索的内容，在完成后台视频后，我将身体背景颜色改为红色。

  $(document).ready(function(){
    $('video').on('ended',function(){
    $("video").first().attr('src','')
         $('html, body').css('background','red');
    });
  });
