3. HTML5 video + DOM

HTML5 的 video 元素同样拥有方法，属性，事件。

以下例子中调用了两个方法： play(), pause();

调用了两个属性， paused, width。

<!DOCTYPE html>
<html>
<body>

<div style="text-align:center;">
<button onclick="playPause()">播放/暂停</button>
<button onclick="makeBig()">大</button>
<button onclick="makeNormal()">中</button>
<button onclick="makeSmall()">小</button>
<br />
<video id="video1" width="420" style="margin-top:15px;">
    <source src="/example/html5/mov_bbb.mp4" type="video/mp4" />
    <source src="/example/html5/mov_bbb.ogg" type="video/ogg" />
    Your browser does not support HTML5 video.
</video>
</div>

<script type="text/javascript">
var myVideo=document.getElementById("video1");

function playPause()
{
if (myVideo.paused)
myVideo.play();
else
myVideo.pause();
}

function makeBig()
{
myVideo.width=560;
}

function makeSmall()
{
myVideo.width=320;
}

function makeNormal()
{
myVideo.width=420;
}
</script>

</body>
</html>
