嵌入式视频未以模式打开

Question

我正在尝试以模式打开我的视频。我正在使用 javascript 创建按钮，在 click 方法上我想用嵌入的 youtube 视频打开模式，但我不断收到 404 错误。我的错误是什么：

我的 json 中有视频 ID，并且正在从那里调用视频 ID。包含表格的模态应该使用 youtube 视频调用另一个模态

我的代码：

JavaScript

json.forEach(elem => {

 let table = $('#table').DataTable({
        data: json,
        columns: [{

        }, {
          data: 'name'

});

let $videoSrc;
$('.vl').click(function() {
  console.log(this);
  $videoSrc = $(this).data("src");
  // console.log($videoSrc);
});

$('#myModal').on('shown.bs.modal', function(e) {

  $("#video").attr('src', $videoSrc + "?autoplay=1&amp;modestbranding=1&amp;showinfo=0");
})

$('#myModal').on('hide.bs.modal', function(e) {
  $("#video").attr('src', $videoSrc);
})

当我单击模式时，我收到 404 错误。

以下方法可行，但您不能在此处执行此操作，因为 YouTube 视频会触发跨站点警告。

与https://youtube.com/ 的跨站点资源关联的cookie 设置为没有SameSite 属性。未来版本的 Chrome 将仅在使用 SameSite=None 和 Secure 设置的情况下提供带有跨站点请求的 cookie

我在这里创建了一个工作演示：https://jsfiddle.net/MrPolywhirl/5xyetqw2/

let json = [{
  date: '2019-04-30',
  name: 'Stack Overflow for Teams - Q&A in a Private and Secure Environment',
  video_id: 'HJtJXMKpl2g'
}, {
  date: '2019-06-04',
  name: 'Stack Overflow Talent - The Best Way to Hire Developers',
  video_id: 'PMDmo4SaP1s'
}, {
  date: '2019-07-19',
  name: 'Stack Overflow for Teams - Share Knowledge & Drive Productivity',
  video_id: 'wmzBz5WSEls'
}];

var $videoSrc = null;

json.forEach(elem => {
  elem.youtube = $('<a>', { id: elem.video_id, class: 'video_link' })
    .attr('data-toggle', 'modal')
    .attr('data-src', `https://www.youtube.com/embed/${elem.video_id}`)
    .attr('data-target', '#video-modal')
    .append($('<i>').addClass('fab fa-youtube'))[0].outerHTML;
});

let table = $('#video-table').DataTable({
  data: json,
  columns: [{
    title: 'Date',
    data: 'date'
  }, {
    title: 'Title',
    data: 'name'
  }, {
    title: 'Link',
    data: 'youtube'
  }]
});

$('#toggle-modal-btn').on('click', function(e) {
  $('.modal').first().modal('toggle');
});

$('#toggle-modal-btn').trigger('click'); // Show the table modal

$('.video_link').click(function(e) {
  $videoSrc = $(this).data('src'); // Update the video source
});

$('#video-modal').on('shown.bs.modal', function(e) {
  $("#video-frame").attr('src', $videoSrc + "?autoplay=1&amp;modestbranding=1&amp;showinfo=0");
});

$('#video-modal').on('hide.bs.modal', function(e) {
  $("#video-frame").attr('src', $videoSrc);
});

.video_link i {
  color: red;
  cursor: pointer;
}

#toggle-modal-btn {
  display: block;
  width: 8em;
  height: 2.5em;
  margin: 0 auto;
  margin-top: calc(50vh - 2.5em);
}
