jQuery不可以使用play()方法,但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:

      document.getElementById("buttonbar").style.display = "block";
      document.getElementById("inputField").style.display = "block";
      // helper functions
      // play video
      function vidplay(evt) {
        if (video.src == "") { // inital source load
        getVideo();
      }
      button = evt.target; // get the button id to swap the text based on the state
      if (video.paused) { // play the file, and display pause symbol
