How do I add new Video entirely from JavaScript?
提问by Light
I am trying to add a new VideoJS object and set it up entirely from JS, without having a DOM video element. The result is that the video is loaded but there aren't any VideoJS controls. Here is the code:
我正在尝试添加一个新的 VideoJS 对象并完全从 JS 设置它，而没有 DOM 视频元素。结果是视频已加载，但没有任何 VideoJS 控件。这是代码：
obj = document.createElement('video');
$(obj).attr('id', 'example_video_1');
$(obj).attr('class', 'video-js vjs-default-skin');
var source = document.createElement('source');
$(source).attr('src', path);
$(source).attr('type', 'video/mp4');
$(obj).append(source);
$("#content").append(obj);
_V_("example_video_1", {}, function () {
//
}
});
I will appreciate any help, thanks!
我将不胜感激任何帮助，谢谢！

Okay took a look at video-js, it's quite nice. Try this:
好吧看了一下video-js，挺不错的。试试这个：

<div id="content"> </div>
<!-- appending video here -->

<video id="example_video_by_hand" class="video-js vjs-default-skin" controls width="640" height="264" poster="http://video-js.zencoder.com/oceans-clip.jpg" preload="auto" data-setup="{}">
<source type="video/mp4" src="http://video-js.zencoder.com/oceans-clip.mp4">

var obj,
source;
obj = document.createElement('video');
$(obj).attr('id', 'example_video_test');
$(obj).attr('class', 'video-js vjs-default-skin');

$(obj).attr('data-height', '264');
$(obj).attr('controls', ' ');
$(obj).attr('poster', 'http://video-js.zencoder.com/oceans-clip.jpg');
$(obj).attr('preload', 'auto');
$(obj).attr('data-setup', '{}');
source = document.createElement('source');
$(source).attr('type', 'video/mp4');
$(source).attr('src', 'http://video-js.zencoder.com/oceans-clip.mp4');
$("#content").append(obj);
$(obj).append(source);
Working exampleon jsbin.
jsbin 上的工作示例。

更新：
As polarblaupointed out in a comment the jQuery.attr()can take an object rather than having to call jQuery.attr()multiple times like in my first example.
正如polarblau在评论中指出的那样，它jQuery.attr()可以接受一个对象，而不必jQuery.attr()像我的第一个例子那样多次调用。
note:The below is just an example and not a working demo.
注意：下面只是一个例子，而不是一个工作演示。
var attributes = {
'id': 'example_video_test',
'class': 'video-js vjs-default-skin',
'width': '640',
'data-height': '264',
'controls': ' ',
'poster': 'http://video-js.zencoder.com/oceans-clip.jpg',
'preload': 'auto',
'data-setup': '{}'
}
var element = $('<video/>').attr(attributes)
//you would also have to add the source element etc but this gives
//a good example of a shorter approach
