我在网页中使用了iframe video。这是我的HTML代码

<iframe id="video1" width="520" height="360" src="http://www.youtube.com/embed/TJ2X4dFhAC0?enablejsapi" frameborder="0" allowtransparency="true" allowfullscreen></iframe>
<a href="#" id="playvideo">Play video</a>

我需要play视频onclick播放视频链接。我怎么能这样做?

这样可行,它会将autoplay=1附加到网址,导致视频开始播放。

附录:如果您的视频来源还没有查询字符串,那么添加?代替&将是谨慎的,有时就是这种情况。这可以通过寻找它的存在来完成。

<iframe id="video1" width="520" height="360" src="http://www.youtube.com/embed/TJ2X4dFhAC0?enablejsapi" frameborder="0" allowtransparency="true" allowfullscreen></iframe>
<a href="#" id="playvideo">Play video</a>
<script>
 //use .one to ensure this only happens once
 $("#playvideo").one(function(){
  //as noted in addendum, check for querystring exitence
  var symbol = $("#video1")[0].src.indexOf("?") > -1 ? "&" : "?";
  //modify source to autoplay and start video
  $("#video1")[0].src += symbol + "autoplay=1";
 });
</script>

然而,大多数人天生就明白,如果他们想要播放视频,他们只需点击它就可以建议将其留给他们或者通过自动播放关闭视频。

还需要提一下,自动播放功能不适用于移动设备(由Android或iOS提供支持)

我正确地设置了src - ?autoplay = 1

   <iframe id="video1" width="450" height="280" src="http://www.youtube.com/embed/TJ2X4dFhAC0?enablejsapi" frameborder="0" allowtransparency="true" allowfullscreen></iframe>
    <a href="#" id="playvideo">Play button</a>
    <script>
     $("#playvideo").click(function(){
      $("#video1")[0].src += "?autoplay=1";
     });
    </script>

因为第一个答案已经有3年了,所以让我指出Youtube Player API。有了它,您可以远程控制您的嵌入式播放器。 见https://developers.google.com/youtube/iframe_api_reference?hl=en

通过小幅调整,您可以通过链接启动视频,而无需重新加载整个iframe:

<!DOCTYPE html>
<html>
  <body>
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <div id="player"></div>

    <!-- The Play-Link will appear in that div after the video was loaded -->
    <div id="play"></div>

    <script>
      // 2. This code loads the IFrame Player API code asynchronously.
      var tag = document.createElement('script');

      tag.src = "https://www.youtube.com/iframe_api";
      var firstScriptTag = document.getElementsByTagName('script')[0];
      firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

      // 3. This function creates an <iframe> (and YouTube player)
      //    after the API code downloads.
      var player;
      function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '390',
          width: '640',
          videoId: 'M7lc1UVf-VE',
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
      }

      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
        //event.target.playVideo();
        document.getElementById('play').innerHTML = '<a href="#" onclick="play();">Play Video</a>';
      }

      function play(){
        player.playVideo();
      }

      // 5. The API calls this function when the player's state changes.
      //    The function indicates that when playing a video (state=1),
      //    the player should play for six seconds and then stop.
      var done = false;
      function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PLAYING && !done) {
          setTimeout(stopVideo, 6000);
          done = true;
        }
      }
      function stopVideo() {
        player.stopVideo();
      }
    </script>
  </body>
</html>

这是另一个例子。请在此处查看:https://codepen.io/rearmustak/pen/VXXOBr

const Player = document.getElementById('player2');
const PlayBtn = document.getElementById('play');
const stopBtn = document.getElementById('stop');
let times = 0, playY;
const playVideo = PlayBtn.addEventListener( 'click' , () => {
    if(times == 0){
      playY = Player.src += '?autoplay=1';
      times = 1;
    }
});

stopBtn.addEventListener( 'click' , () => {
    playY = playY.slice(0, -11);
    Player.src = playY
    times = 0;
});
.video-frame{
  overflow: hidden;
  margin-bottom: 10px;
}
button{
  border: none;
  background-color: #e75252;
  color: #ffffff;
  padding: 10px 15px;
  border-radius: 3px;
  cursor: pointer;
}
button:focus{
  outline: 0;
}
#stop{
  background-color: #ff0002;
}
<h1>Youtube video Play/Stop</h1>

<div class="video-frame">
  <iframe id="player2" width="560" height="315" src="https://www.youtube.com/embed/cs1e0fRyI18" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>

<button id="play">Play</button>
<button id="stop">Stop</button>

这里是示例http://jsfiddle.net/WYwv2/5/

的链接

看看这个

<!DOCTYPE html> 
<html> 
<body> 
<a href="#" id="playvideo" onclick="playme()">Play video</a>
    <iframe id="video1" width="520" height="360"  frameborder="0" ></iframe>
<script>
function playme() {
document.getElementById("video1").src = 'http://www.w3schools.com/tags/mov_bbb.mp4';
}
</script>
</body> 
</html>
​

我们动态设置视频源。

这对我有用。 请检查一下。

$("#player").on("pause", function(e) {
          clearTimeout(playTimeout);
      });
      var tag = document.createElement('script');
      tag.src = "https://www.youtube.com/iframe_api";
      var firstScriptTag = document.getElementsByTagName('script')[0];
      firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    
      var player;
        function onYouTubeIframeAPIReady() {
          player = new YT.Player('player', {
            height: '390',
            width: '640',
            videoId: 'M7lc1UVf-VE',
            events: {
              'onReady': onPlayerReady,
              'onStateChange': onPlayerStateChange
            }
          });
        }
      function onPlayerReady(event) {
        event.target.playVideo();
          }
       var done = false;
        function onPlayerStateChange(event) {
          if (event.data == YT.PlayerState.PLAYING && !done) {
            setTimeout(stopVideo, 2000);//replace time here 
            $("#player").get(0).load();
            $("#player").get(0).pause();
            done = true;
          }
        }
        function stopVideo() {
          player.stopVideo();
        }
