在此任务中，他们希望我单击缩略图后将此JSON对象中的视频加载到相应的播放器中。如果可能的话，我没有真正的线索，我已经在过去的一个小时中进行了研究，但我一生中找不到任何东西。我的代码如下
var json = {

的HTML
<div data-bind="foreach: screens">
<div class="container" data-bind="with: config">
<div class="row" data-bind="foreach: views">
<div class="col-md-6">
<div class="card">
<!--This line should load the video-->
<img class="card-img-top" data-bind="attr: { src: thumbnail }">
<div class="card-body">
<h5 class="card-title" data-bind="text:title"> </h5>
<p class="card-text" data-bind="text:info"> </p>
</div><!-- card content -->

任何事情都将不胜感激。
最佳答案
基于演示here，您可以使用<video>标记：
<!-- ko if: type() === 'smPlayerIframe' -->
<video width="320" height="240" controls>
<!-- ko foreach: files -->
<source data-bind="attr: { src: url, type: 'video/' + type() }" />
<!-- /ko -->
Your browser does not support the video tag.
</video>
<!-- /ko -->
关于javascript - 必须将视频从JSON对象加载到div中，这可以通过 knockout 完成吗？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/57341789/
