问题描述
首先，我要感谢 Kosmos 的出色表现，感谢他的
First I want to say thanks to Kosmos for his amazing answer.
如何控制youtube视频播放和播放暂停取决于帧或播放器的可见性.有没有办法通过带有HTML标签的youtube嵌入视频来做到这一点?
How to control youtube video play & pause depend on visibility of the frame or player. Is there any way to do this with youtube embed videos with HTML Tabs?
例如:
<br><br><br>
<div class="container">
<ul class="tabs">
<li class="tab-link current" data-tab="tab-1">Tab One</li>
<li class="tab-link" data-tab="tab-2">Tab Two</li>
<li class="tab-link" data-tab="tab-3">Tab Three</li>
<li class="tab-link" data-tab="tab-4">Tab Four</li>
</ul>
<div id="tab-1" class="tab-content current">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
</div>
<div id="tab-2" class="tab-content">
Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
</div>
<div id="tab-3" class="tab-content">
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
</div>
<div id="tab-4" class="tab-content">
<iframe id="playerA" width="300" height="220" src="https://www.youtube.com/embed/0_P4pKbvaII?rel=0" frameborder="0" allowfullscreen></iframe>
</div>
</div><!-- container -->
如果上面的框架可见视频自动播放，并且该框架隐藏或向下滚动，例如 DEMO jsfiddle 它将自动暂停.
If the above frame visible the video autoplay and if the frame hide or scroll down like DEMO jsfiddle it will auto pause.
JS Kosmos ，它是
JS Answer from Kosmos which is works great with scroll method (thanks to him) that mean if user scroll away the video pause and if again scroll to video frame in viewport it start playing. No My Question is how can implement this with HTML tabs
var LoadVideo = function(player_id){
var Program = {
Init: function(){
this.NewPlayer();
this.EventHandler();
},
NewPlayer: function(){
var _this = this;
this.Player = new YT.Player(player_id, {});
_this.Player.$element = $('#' + player_id);
},
Play: function(){
if( this.Player.getPlayerState() === 1 ) return;
this.Player.playVideo();
},
Pause: function(){
if( this.Player.getPlayerState() === 2 ) return;
this.Player.pauseVideo();
},
ScrollControl: function(){
if( Utils.IsElementInViewport(this.Player.$element[0]) ) this.Play();
else this.Pause();
},
EventHandler: function(){
var _this = this;
$(window).on('scroll', function(){
_this.ScrollControl();
});
}
};
var Utils = {
/** @author https://stackoverflow.com/a/7557433/1684970 */
IsElementInViewport: function(el){
if (typeof jQuery === "function" && el instanceof jQuery) el = el[0];
var rect = el.getBoundingClientRect();
return (
rect.top >= 0 &&
rect.left >= 0 &&
rect.bottom <= (window.innerHeight || document.documentElement.clientHeight) &&
rect.right <= (window.innerWidth || document.documentElement.clientWidth)
);
}
};
Program.Init();
};
window.onload = function(){
LoadVideo('playerA');
LoadVideo('playerB');
LoadVideo('playerC');
// or (loop mode)
//$('iframe').each(function(){
// LoadVideo($(this).attr('id'));
//});
};
请帮助或分享您的想法将不胜感激. 谢谢！
Please help or share your idea will be highly appreciate. Thanks!

好吧，我举了一个简单的示例，使用Youtube Iframe API来完成您想要的工作.
Well, I made a simple example to do what you are looking for using the Youtube Iframe API.
这是jsfiddle: https://jsfiddle.net/kmsdev/gsfkL6xL/
Here's the jsfiddle: https://jsfiddle.net/kmsdev/gsfkL6xL/
这是代码(请参阅API文档以更好地理解它):
And here's the code (see the API docs to understand it better):
示例代码已更新，以匹配OP请求.我刚刚添加了一个活动 监听 tab 点击事件的处理程序.别忘了附加
&enablejsapi=1到iframe源网址，否则该API将无法正常工作. 由于现在的想法不仅仅是播放和停止视频 滚动显示，也许这段代码不是最好的选择，但它仍然是 解决方法.
Example code updated to match OP requests. I just added an event handler to listen to tab click events. Don't forget to append
&enablejsapi=1to the iframe source url, else the API won't work. Since the idea now is a little more than just play and stop the videos by scroll, maybe this code is not the best option, but it is still a workaround.
更新了jsFiddle: https://jsfiddle.net/kmsdev/gsfkL6xL/3/
Updated jsFiddle: https://jsfiddle.net/kmsdev/gsfkL6xL/3/
var LoadVideo = function(player_id){
var Program = {
Init: function(){
this.NewPlayer();
this.EventHandler();
},
NewPlayer: function(){
var _this = this;
this.Player = new YT.Player(player_id, {});
_this.Player.$element = $('#' + player_id);
},
Play: function(){
console.log(this.Player.IsReady);
if( this.Player.getPlayerState() === 1 ) return;
this.Player.playVideo();
},
Pause: function(){
if( this.Player.getPlayerState() === 2 ) return;
this.Player.pauseVideo();
},
ScrollControl: function(){
if( Utils.IsElementInViewport(this.Player.$element[0]) ) this.Play();
else this.Pause();
},
EventHandler: function(){
var _this = this;
$(window).on('scroll', function(){
_this.ScrollControl();
});
$('.tab-link').on('click', function(){
var $target = $('#' + $(this).data().tab);
if( !!$('iframe', $target).length && $('iframe', $target).attr('id') == _this.Player.$element.attr('id') ){
_this.Play();
}
});
}
};
var Utils = {
/** @author http://stackoverflow.com/a/7557433/1684970 */
IsElementInViewport: function(el){
if (typeof jQuery === "function" && el instanceof jQuery) el = el[0];
var rect = el.getBoundingClientRect();
return (
rect.top >= 0 &&
rect.left >= 0 &&
rect.bottom <= (window.innerHeight || document.documentElement.clientHeight) &&
rect.right <= (window.innerWidth || document.documentElement.clientWidth)
);
}
};
Program.Init();
};
window.onload = function(){
LoadVideo('playerA');
LoadVideo('playerB');
};
可以随意使用和修改它.
Feel free to use and modify it for your purpose.
