更改视频时如何运行插件/库? [英] How to run plugin / library when changing video?

问题描述

执行代码时，videoJS 插件取代了HTML5视频播放器，我非常高兴，我在我之间说过我所取得的成就.

When executing the code the videoJS plugin replaces the HTML5 video player, and really happy, I said between me what I achieved.

但是，当单击下一个视频时，即使返回到第一个视频，插件也会丢失，这使我成为默认的HTML5

But when clicking on the next video, even when returning to the first video, the plugin is lost, leaving me the default player of HTML5

您可以在 jsfiddle 或此处进行检查:

我认为videoJS 插件 videoJS不适用于同一页面上的多个视频，但实际上如果它适用于多个视频，请进行以下测试:

I thought that the videoJS plugin videoJS not work for several videos on the same page, but really if it works for several videos here the test: https://jsfiddle.net/bq81phfy/

所以我能想到的是，可能的解决方案是同时切换到下一个视频或返回上一个视频，同时运行videoJS 插件.

So what I can think of is that a possible solution is to run the videoJS plugin at the same time by switching to the next video or going back to the previous video.

我的问题:如何使插件的库运行? O如何使插件适用于所有视频?

My problem: How do I get the plugin's libraries to run? O How to make the plugin work for all videos?

推荐答案

(修订后的答案)

有关完整的代码和演示，您可以在此处查看我的小提琴.

For the full code and demo, you can check my Fiddle here.

我的方法如下:

• 所有视频链接仅包含一个video元素.

在显示非视频内容时，video被隐藏.

When displaying a non-video content, the video is hidden.

显示视频时，非视频内容将被删除.

When displaying a video, the non-video content are removed.

您可以从以下代码中看到我更改/添加的内容:

And you can see what I changed/added from below code:

(...表示您的代码，在那里没有任何更改.)

(The ... means your code, nothing changed there.)

$(document).ready(function() {
  function insertar_contenido(vid, elemento) {

    ...

    contenido = vid.find('video:first');
    var videojs = contenido.closest('.video-js');
    var exists = videojs.length >= 1;

    if (es_video) {
      if (exists) {
        vid.children('.non-video').remove();
        videojs.show();

        fuente = contenido.children('source');
        fuente.attr('src', url);
        fuente.attr('type', 'video/' + formato);

        contenido.attr('src', url);
        contenido.get(0).load();
      } else {
        ...

        vid.html('');
        vid.append(contenido);
      }
    } else {
      if (exists) {
        videojs.hide();
      }

      ...

      contenido.addClass('non-video');
      vid.append(contenido);
    }
    ...
  }

  ...
});

更新

实际上，对于内联内容，该元素应首先隐藏:

UPDATE

Actually, for inline content, the element should be initially hidden:

<div id="c_inline-1" style="display: none">
  <h3>Inline Content</h3>
  <p>Content goes here.</p>
</div>

为此，我将contenido.append($("#c_" + id))更改为:

contenido.append($("#c_" + id).html())

演示此处.

或者，如果您希望为每个视频使用一个新的video元素，则只需原始代码vid.append(contenido)之后之后中添加这些行>:

Alternatively, if you'd rather use a new video element for each video, then just call videojs() on the created video element. Just add these lines after the vid.append(contenido) in your original code:

if (es_video) {
  videojs(contenido.get(0));
}

演示此处.

我添加了这个:

// If clicking on the same link, do nothing.
if (vid.data('elemento') === elemento.get(0)) {
  return;
}
vid.data('elemento', elemento.get(0));

和这个:

// .non-video are always re-created.
vid.children('.non-video').remove();

到insertar_contenido()函数，该函数应解决此问题:"在列表iFrame和Inline的标题上单击几次.相同的内容使单击的相同次数增加了一倍".

to the insertar_contenido() function, which should fix this issue: "Click several times on the title of the listing iFrame and Inline. And the same content is doubling the same number of times you click".

演示此处.
