jquery - 更改视频时如何运行插件/库？

Question

当执行代码时，videoJS plugin 取代了 HTML5 视频播放器，真的很高兴，我说了我之间的成就。

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，让我使用HTML5

的默认播放器

可以在jsfiddle中查看或在这里:

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

我认为 videoJS plugin 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或返回到上一个来同时运行 videoJS plugin视频。

我的问题:如何让插件的库运行？ O 如何使插件适用于所有视频？

Answer 1

(修改后的答案)

完整代码和demo，可以查看我的Fiddle here .

我的做法是这样的:

• 所有视频链接只有一个 video 元素。

• 当显示非视频内容时，video 被隐藏。

• 显示视频时，会移除非视频内容。

你可以从下面的代码中看到我更改/添加的内容:

(... 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，该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，如果您更愿意为每个视频使用新的 video 元素，那么只需 call videojs()在创建的 video 元素上。只需在您的 original code 中的 vid.append(contenido) 之后 添加这些行:

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();

到 insertar_contenido() 函数，它应该可以解决这个问题:“多次单击列表 iFrame 和 Inline< 的标题。相同内容的点击次数翻倍。”。

演示 here .
