使用jQuery控制HTML5视频播放/暂停

我尝试用jQuery控制HTML5视频，两个视频分别在两个tab中，我希望点中tab后，该tab里的视频可以立即播放，而另外tab里的视频能够停止。
我的代码是这样的：
$('#playMovie1').click(function(){
$('#movie1').play();
});但发现这样不行，而用以下的js是可以的：
document.getElementById('movie1').play();
解决方法：
play并不是jQuery的函数，而是DOM元素的函数，所以我们需要通过DOM来调用play，代码如下：
$('#videoId').get(0).play();
最简单的方法实现Play和Pause:
$('video').trigger('play'); $('video').trigger('pause');
点击视频就能播放和暂停
$("video").trigger("play");//for auto play
$("video").addClass('pause');//for check pause or play add a class
$('video').click(function() {
if ($(this).hasClass('pause')) {
$("video").trigger("play");
$(this).removeClass('pause');
$(this).addClass('play');
} else {
$("video").trigger("pause");
$(this).removeClass('play');
$(this).addClass('pause');
}
})静音和取消静音
$('body').find("video").attr('id', 'video')
var myVid = document.getElementById("video");
$('.sound-icon').click(function() {
//here "sound-icon" is a anchor class.
var sta = myVid.muted;
if (sta == true) {
myVid.muted = false;
} else {
myVid.muted = true;
}
})HTML 5中播放视频的方法：
Try this page in Safari 4! Or you can download the video instead.
自动播放：
<video src="abc.mov" autoplay> </video>
使用poster在视频无法加载时显示图片：
<video width="640" height="360" src="http://www.youtube.com/demo/google_main.mp" autobuffer controls poster="whale.png"> <p>Try this page in Safari 4! Or you can <a href="http://www.youtube.com/demo/google_main.mp4">download the video</a> instead.</p> </video>
一个比较简洁的例子：
<script type="text/javascript">
function vidplay() {
var video = document.getElementById("Video1");
var button = document.getElementById("play");
if (video.paused) {
video.play();
button.textContent = "||";
} else {
video.pause();
button.textContent = ">";
}
}
function restart() {
var video = document.getElementById("Video1");
video.currentTime = 0;
}
function skip(value) {
var video = document.getElementById("Video1");
video.currentTime += value;
}
</script>
</head>
<body>
<video id="Video1" >
// Replace these with your own video files.
<source src="demo.mp4" type="video/mp4" />
<source src="demo.ogv" type="video/ogg" />
HTML5 Video is required for this example.
<a href="demo.mp4">Download the video</a> file.
</video>
<p id="buttonbar">
<button id="restart" onclick="restart();">[]</button>
<button id="rew" onclick="skip(-10)"><<</button>
<button id="play" onclick="vidplay()">></button>
<button id="fastFwd" onclick="skip(10)">>></button>
