HTML5 视频 JavaScript

我没有 Javascript 经验，我有以下脚本在 Andriod 手机上播放视频文件，并且运行良好。

 <script type="text/javascript">
        function PlayMyVideo(arg) {
            var myVideo = document.getElementById([arg]);
            myVideo.play();
        }
    </script>
<video id="what" src="what.mp4" poster="" />
<input type="button" onclick="PlayMyVideo('what')" value="Play" />

我正在尝试即时编写标签：

  <script type="text/javascript">
        function PlayVideo() {
            new_video = document.createElement('video');
            new_video.setAttribute('scr', 'what.mp4'); 
            new_video.play(); 
         }
    </script>
<input type="button" onclick="PlayVideo()" value="Play2" />

没有发生任何事情，将不胜感激您的建议。提前致谢

I am not experienced in Javascript, I have the following script to play video files on Andriod phone, and it works fine.

 <script type="text/javascript">
        function PlayMyVideo(arg) {
            var myVideo = document.getElementById([arg]);
            myVideo.play();
        }
    </script>
<video id="what" src="what.mp4" poster="" />
<input type="button" onclick="PlayMyVideo('what')" value="Play" />

I am trying to write the tag on the fly:

  <script type="text/javascript">
        function PlayVideo() {
            new_video = document.createElement('video');
            new_video.setAttribute('scr', 'what.mp4'); 
            new_video.play(); 
         }
    </script>
<input type="button" onclick="PlayVideo()" value="Play2" />

Nothing happen, would appreciate your suggestions.
Thanks in advance

new_video.setAttribute('scr', 'what.mp4');

“scr”拼写错误。它应该是“src”。

而且你应该在播放之前等待电影加载

new_video.setAttribute('scr', 'what.mp4');

'scr' is misspelled. It should be 'src'.

and also you should wait for the movie to load before play

好吧，您没有将新创建的标签附加到任何内容，因此它无法播放，因为它位于“内存”/“无效”中，而不是在屏幕上。

<div id='plc'> </div>

<script type='text/javascript'>
function PlayVideo() {
new_video = document.createElement('video');
document.getElementById('plc').appendChild(new_video);
new_video.setAttribute('scr', 'what.mp4');
new_video.play();
}

Well you're not appending the newly created tag to anything, so it can't play because it's in "memory"/"void", not on the screen.

<div id='plc'> </div>

<script type='text/javascript'>
function PlayVideo() {
new_video = document.createElement('video');
document.getElementById('plc').appendChild(new_video);
new_video.setAttribute('scr', 'what.mp4');
new_video.play();
}
