Javascript 当弹出窗口未出现时，视频弹出窗口自动播放。我仍然能听到声音

我将此弹出窗口添加到我的网站，并尝试添加自动播放，但问题是即使每次刷新网站时弹出窗口都不会出现，您仍然可以听到声音。当弹出窗口未显示时，如何停止自动播放

我试图通过这样做来解决问题，但仍然不起作用

<script>
$( document ).ajaxComplete(function() {
    $("#popup_87 flex-video iframe").attr("src","https://www.youtube.com/embed/vYAVyEdBfEU?rel=0&autoplay=1;showinfo=0");
});
</script> 



    <!-- START POPUP CODE -->
    <div id="popup_87" class="reveal-modal small" data-reveal aria-labelledby="popvideo" aria-hidden="true" role="dialog">
        <div class="flex-video widescreen"> 
        <iframe src="https://www.youtube.com/embed/vYAVyEdBfEU?rel=0&amp;showinfo=0&amp;autoplay=1" allowfullscreen="" frameborder="0" height="360" width="640"></iframe>
        </div>
        <a class="close-reveal-modal" aria-label="Close">&#215;</a>
    </div>
    <div class="hide">

不确定是否要将此添加到ajaxComplete事件中。任何ajax调用都会调用此函数，这可能是您不想要的，并且在整个页面中都有随机行为。您将希望根据打开或关闭弹出窗口的时间触发功能。您好，蓝眼睛，我已经尝试了此代码，但它仍然不是自动播放。其他功能在哪里f您的代码？很难弄清楚您在做什么。很抱歉，我还是新手，非常感谢您的帮助，此弹出窗口是一个小部件。我尝试将loadvideo放在那里，但一直无法工作。您需要将其放在触发弹出窗口的位置
