Question

这是视频

if(Name.HasChanged)
{
    if(string.IsNullOrEmpty(Name.NewValue))
        Name.DiscardChanged();
}

我想停止或暂停它，这可能吗？我只想坚持使用iframe

js / jquery中的任何函数都是相同的吗？

Answer 1

是的，您可以从iframe访问您的视频，但这仅在帧源位于同一域时才有效。如果它来自不同的域，跨域脚本（XSS）保护将启动。

我认为您正在播放来自您网域的视频，（嵌入式iframe网址域与网页域大致相同）。

测试：

去这里： http://cache4.asset-cache.net/

并在控制台中运行此代码：

var video = undefined;
//define iframe in html
ifrm = document.createElement("IFRAME"); 
ifrm.setAttribute("src", "http://cache4.asset-cache.net/xd/468140002.mp4?v=1&c=IWSAsset&k=2&d=72990B68305E4FDFEE95B69A879131BCD6D7111452E48A17C03F8342D660D5A451EBC1DEC2A827C9&b=RTdG"); 
ifrm.setAttribute("id", "vt");
ifrm.setAttribute("width","420");
ifrm.setAttribute("autoplay","false"); 
ifrm.setAttribute("height","345");
document.body.appendChild(ifrm); 

//iframe load event
ifrm.onload = function() {
    var btnPlay = document.createElement("BUTTON");
    btnPlay.setAttribute("onclick", "play();");
    var t1 = document.createTextNode("PLAY ME");       
    btnPlay.appendChild(t1);                               
    document.body.appendChild(btnPlay);

    var btnPause = document.createElement("BUTTON");        
    btnPause.setAttribute("onclick", "pause();");
    var t2 = document.createTextNode("PAUSE ME");      
    btnPause.appendChild(t2);                              
    document.body.appendChild(btnPause);

    video = document.getElementById("vt").contentWindow.document.body.getElementsByTagName('video')[0];
}


//play stop methods
function play()
{
  if (video != undefined)
    video.play();
  return false;
}

function pause()
{
  if (video != undefined)
    video.pause();
  return false;
}

如果您的iframe源与您的域不同，则无法控制来自帧的视频。以上是跨站点脚本编写不会影响您时如何控制视频。

我正在使用此html和JS代码为您提供解决方案，以停止我的视频，在视频库中播放暂停的视频。

    <script>
      var slideIndexVid = 1;
      showSlidesVid(slideIndexVid);
      
      function plusSlidesVid(n) {

        
        showSlidesVid(slideIndexVid += n);
      }
      
      function currentSlideVid(n) {
        showSlidesVid(slideIndexVid = n);
      }
      
      function showSlidesVid(n) {
        var i;
        var slidesVid = document.getElementsByClassName("vid-slides");
        var dotsVid = document.getElementsByClassName("dot-vid");

       
        $('#vidS1')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
        $('#vidS2')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
        $('#vidS3')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
        $('#vidS4')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
        $('#vidS5')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
        $('#vidS6')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
        
        
        if (n > slidesVid.length) {slideIndexVid = 1}
        if (n < 1) {slideIndexVid = slidesVid.length}
        for (i = 0; i < slidesVid.length; i++) {
          slidesVid[i].style.display = "none";
        }
        for (i = 0; i < dotsVid.length; i++) {
            dotsVid[i].className = dotsVid[i].className.replace(" active-vid", "");
        }
        
        slidesVid[slideIndexVid-1].style.display = "block";
        dotsVid[slideIndexVid-1].className += " active-vid";      
      }  
    </script>

Answer 3

我遇到了同样的问题，我花了几个小时后试图在iframe暂停我本地/一个域（S3服务器）的视频。我知道如果我们从本地或一个域获取视频而不是我们使用视频标记，它会提供更多控件，我已经为youtube视频使用了iframe

这里是代码，这里的默认控件是暂停

            <video width='200' height='180' src="" style='position:absolute;width:100%;height:100%;left:0' controls>
            </video>

启用自动播放

        <video width='200' height='180' src="" style='position:absolute;width:100%;height:100%;left:0' controls autoplay>
        </video>

这将节省您的时间并为您提供更多控制

是否可以在iframe上停止/暂停视频？
