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：

1
2
3
$( '#playMovie1' ).click(function(){
$( '#movie1' ).play();
});

但发现这样不行，而用以下的js是可以的：

1
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：

1
$( '#videoId' ).get( 0 ).play();

最简单的方法实现Play和Pause:

1
2
$( 'video' ).trigger( 'play' );
$( 'video' ).trigger( 'pause' );


点击视频就能播放和暂停

10
11
12
13
$( "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：

1
2
3
4
<video width= "640" height= "360" src= "http://www.youtube.com/demo/google_main.mp4" controls autobuffer>
<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>

自动播放：

1
2
<video src= "abc.mov" autoplay>
</video>

使用poster在视频无法加载时显示图片：

1
2
3
<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>

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>
<div id= "buttonbar" >
<button id= "restart" οnclick= "restart();" >[]</button>
<button id= "rew" οnclick= "skip(-10)" >&lt;&lt;</button>
<button id= "play" οnclick= "vidplay()" >&gt;</button>
<button id= "fastFwd" οnclick= "skip(10)" >&gt;&gt;</button>
</div>
