换视频时如何运行插件/库?

How to run plugin / library when changing video?

执行代码时,videoJS 插件 替换了 HTML5 视频播放器,真的很高兴,我说了我所取得的成就。

但是当点击下一个视频时,即使返回第一个视频,插件也丢失了,让我的默认播放器是HTML5

您可以在 jsfiddle 或此处查看:

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

    var contenido, fuente
    var url = elemento.attr("href")
    var ext = "mp4"
    var formato = ext
    var es_video = new RegExp("^.+\." + ext + "$").test(url)
    var cargando = $('.loading')

    function mostrar() {
      cargando.fadeIn(200)
    }

    function ocultar() {
      cargando.fadeOut(100)
    }
    mostrar()
    var cuadro = vid.find(".cuadro")
    if (cuadro.length != 0) {
      $("#ocultado").append(cuadro)
    }
    if (es_video) {
     var json = {"aspectRatio":"640:267", "playbackRates": [1, 1.5, 2]};
     contenido = $(document.createElement("video"))
     fuente = $(document.createElement("source"))
     fuente.attr("src", url)
     fuente.attr("type", "video/" + formato)
     contenido.attr("controls", true)
     contenido.attr("autoplay", true)
     contenido.attr("class","video-js")
     contenido.attr('data-setup', JSON.stringify(json));
     contenido.on('waiting', mostrar)
     contenido.on('canplay', ocultar)
     contenido.append(fuente)
    } else {
      var id = elemento.attr("id")
      if (id == undefined) {
        contenido = $(document.createElement("iframe"))
        contenido.attr("src", url)
        contenido.on('load', ocultar)
      } else {
        contenido = $(document.createElement("div"))
        contenido.append($("#c_" + id))
        ocultar()
      }
    }
    vid.html("")
    vid.append(contenido)
    $("#enlaces a").removeClass("playing")
    elemento.addClass("playing")
  }

  var indice = 0
  var vid = $('#myvid')
  var primer_elemento = $("#enlaces a:first")
  var enlaces = $("#enlaces a").map((x, y) => {
    return {
      a: x,
      b: y
    }
  })

  insertar_contenido(vid, primer_elemento)
  primer_elemento.addClass("playing")

  $("#enlaces a.link").on("click", function(event) {
    event.preventDefault()
    var esto = $(this)

    indice = enlaces.filter((x, y) => y.b == this)[0].a

    insertar_contenido(vid, esto)
  })
  $("#atras").on("click", function(event) {
    event.preventDefault()
    var esto = $(this)
      --indice
    if (indice < 0) {

    }
    enlaces[indice].b.click()
  })
  $("#siguiente").on("click", function(event) {
    event.preventDefault()
    var esto = $(this)
      ++indice
    if (indice >= enlaces.length) {
      indice -= enlaces.length

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此处的多个视频测试:https://jsfiddle.net/bq81phfy/

所以我能想到的是,一个可能的解决方案是通过切换到下一个视频来同时 运行 videoJS plugin或返回上一个视频。

我的问题:如何将插件的库获取到 运行? O 如何使 插件 适用于所有视频?

(修改后的答案)

完整代码和demo,可以查看我的Fiddle here.

而我的做法如下:

  • 所有视频链接只有一个 video 元素。

  • 当显示non-video内容时,video被隐藏。

  • 显示视频时,non-video内容被删除。

你可以从下面的代码中看到我changed/added:

... 表示您的代码,那里没有任何更改。)

$(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,元素最初应该是隐藏的:

<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 here.

更新 2

或者,如果您希望为每个视频使用新的 video 元素,则只需 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 here.

更新 3

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));

还有这个:

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

insertar_contenido() 函数,它应该可以解决这个问题:“多次单击列表 iFrameInline 的标题。同样内容的点击次数翻了一番”。

演示 here.
