使用jQuery播放/暂停 HTML5视频

文章来自：http://blog.okbase.net/jquery2000/archive/4485.html

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" 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：

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

下面是一个比较完整的例子：

0 : 1; } } // button events // Play document.getElementById("play").addEventListener("click", vidplay, false); // Restart document.getElementById("restart").addEventListener("click", function () { setTime(0); }, false); // Skip backward 10 seconds document.getElementById("rew").addEventListener("click", function () { setTime(-10); }, false); // Skip forward 10 seconds document.getElementById("fwd").addEventListener("click", function () { setTime(10); }, false); // set src == latest video file URL document.getElementById("loadVideo").addEventListener("click", getVideo, false); // fail with message video.addEventListener("error", function (err) { errMessage(err); }, true); // volume buttons document.getElementById("volDn").addEventListener("click", function () { setVol(-.1); // down by 10% }, false); document.getElementById("volUp").addEventListener("click", function () { setVol(.1); // up by 10% }, false); // playback speed buttons document.getElementById("slower").addEventListener("click", function () { video.playbackRate -= .25; }, false); document.getElementById("faster").addEventListener("click", function () { video.playbackRate += .25; }, false); document.getElementById("normal").addEventListener("click", function () { video.playbackRate = 1; }, false); document.getElementById("mute").addEventListener("click", function (evt) { if (video.muted) { video.muted = false; evt.target.innerHTML = "<img alt='volume on button' src='vol2.png' />" } else { video.muted = true; evt.target.innerHTML = "<img alt='volume off button' src='mute2.png' />" } }, false); } // end of runtime }// end of master </script>   </head> <body onload="init();" >   <video id="Video1" controls style="border: 1px solid blue;" height="240" width="320" title="video element"> HTML5 Video is required for this example </video>   <div id="buttonbar" style="display: none;")> <button id="restart" title="Restart button">[]</button> <button id="slower" title="Slower playback button">-</button> <button id="rew" title="Rewind button" >&lt;&lt;</button> <button id="play" title="Play button">&gt;</button> <button id="fwd" title="Forward button" >&gt;&gt;</button> <button id="faster" title="Faster playback button">+</button> <button id="Button2" title="Mute button" ><img alt="Volume on button" src="vol2.png" /></button> <br /> <label>Playback </label> <label>Reset playback rate: </label><button id="normal" title="Reset playback rate button">=</button>   <label> Volume </label> <button id="volDn" title="Volume down button">-</button> <button id="volUp" title="Volume up button">+</button> <button id="mute" title="Mute button" ><img alt="Volume on button" src="vol2.png" /></button> </div> <br/> <div id= "inputField" style="display:none;" > <label>Type or paste a video URL: <br/> <input type="text" id="videoFile" style="width: 300px;" title="video file input field" value="http://ie.microsoft.com/testdrive/ieblog/2011/nov/pp4_blog_demo.mp4" /> <button id="loadVideo" title="Load video button" >Load</button> </label> </div> <div title="Error message area" id="errorMsg" style="color:Red;"></div> </body> </html>
