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：
`<video width=``"640"` `height=``"360"` `src=``"[http://www.youtube.com/demo/google_main.mp4](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](http://www.youtube.com/demo/google_main.mp4)"``>download the video</a> instead.</p>` `</video>`
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](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](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>`
`<div 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>`
`</div>`
