在上一个问题中，我问到如何在iFrame中播放视频，并得到了答案：How to click from a video link and let it play in an area below?
但是现在我面临另一个问题，我有一个iFrame和一个关闭[x]按钮[灵感来自：http://jsfiddle.net/EFbzY/1/]，但是我不知道如何激活该关闭按钮来关闭iFrame，网站结尾处的html和脚本代码如下所示，用于控制iFrame：
<div id="modal" tabindex="-1">
<button type="button" data-dismiss="modal" class="close" title="close">×</button>
<div class="content">
<h4 class="title"></h4>
<iframe class="yt-video" src="https://www.youtube.com/embed/A1nRiiWYgZw" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>
<div id="fade" class="black_overlay" onclick="closeLightBox()" style="display: block;">
<div style=" z-index: 0; left: 76%; top: 17%; width: 22px; position: absolute;">
<h2>×</h2>
</div>
</div>
</div>
<script>
var modal = document.getElementById('modal'),
closeBtn = modal.querySelector('close'),
ytVideo = modal.querySelector('.content .yt-video'),
title = modal.querySelector('.content .title'),
anchors = document.querySelectorAll('a[data-target="modal"]'),
l = anchors.length;
for (var i = 0; i < l; i++)
{
anchors[i].addEventListener("click", function(e)
{
e.preventDefault();
title.textContent = this.dataset.videoTitle || 'No title';
ytVideo.src = this.href;
modal.classList.toggle('is-visible');
modal.focus();
});
}
modal.addEventListener("keydown", function(e)
{
if (e.keyCode == 27)
{
title.textContent = '';
ytVideo.src = '';
this.classList.toggle('is-visible');
}
});
closeBtn.addEventListener("click", function(e)
{
e.preventDefault();
title.textContent = '';
ytVideo.src = '';
modal.classList.toggle('is-visible');
});
</script>
[页面顶部]的样式代码如下：
#modal {
display: none;
position: fixed;
width: 100vw;
height: 100vh;
max-height: 100vh;
top: 0;
left: 0;
background: rgba(24, 24, 24, .6);
z-index: 999;
}
#modal .content {
width: 55%;
height: 65vh;
margin: auto; /* allows horyzontal and vertical alignment as .content is in flex container */
}
#modal .content .yt-video {
display: block;
width: 100%;
height: calc(100% - 45px);
}
#modal .content .title {
box-sizing: border-box;
height: 45px;
line-height: 23px;
padding: 12px 4px;
margin: 0;
background: #007bff;
max-width: 100%;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
#modal .close {
position: absolute;
top: 0;
right: 0;
width: 35px;
height: 35px;
line-height: 35px;
text-align: center;
border: 0;
font-weight: bold;
font-size: 24px;
color: #fff;
background: #666;
cursor: pointer;
transition: background .4s;
}
#modal .close:hover, #modal .close:active {
background: #ef3658;
}
#modal.is-visible {
display: flex;
}
测试站点位于：http://gatecybertech.com/test
在网站的右上角，单击“视频”链接将带您到该部分，单击视频后，将打开iFrame并使用右上角的[x]按钮播放视频，但尚未激活，如何修复它以关闭iFrame和视频？

好的，经过一些研究和实验，我终于明白了。它的运行位置：http://gatecybertech.com/test之后将移至主站点：http://gatecybertech.com
[1]样式如下：
#modal {
display: none;
position: fixed;
width: 100vw;
height: 100vh;
max-height: 100vh;
top: 0;
left: 0;
background: rgba(24, 24, 24, .6);
z-index: 999;
}
#modal .content {
width: 55%;
height: 65vh;
margin: auto; /* allows horyzontal and vertical alignment as .content is in flex container */
}
#modal .content .yt-video {
display: block;
width: 100%;
height: calc(100% - 45px);
}
#modal .content .title {
box-sizing: border-box;
height: 45px;
line-height: 23px;
padding: 12px 4px;
margin: 0;
background: #007bff;
color: #fff;
text-align: center;
font-size: 26px;
max-width: 100%;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
#modal .close {

transition: background .2s;
}
#modal .close:hover, #modal .close:active {

#modal.is-visible {
display: flex;
}
[2] HTML看起来像这样：
<div class="tools-icon">
<a href=https://www.youtube.com/embed/IgBIaZgoAQc?autoplay=1 target=_blank data-target="modal" data-video-title="Keypad Pins Easily Stolen"><img src=https://i.ytimg.com/vi/IgBIaZgoAQc/hqdefault.jpg?sqp=-oaymwEXCPYBEIoBSFryq4qpAwkIARUAAIhCGAE=&rs=AOn4CLDW3KcjXsTR5utmlvhFfibLe-bvRg width=170 height=110></a>
<p class="tools-icon__text">Keypad Pins Easily Stolen</p>
</div>
...
<!-- the modal div that will open when an anchor link is clicked to show the related video in an iframe. -->
<div id="modal" tabindex="-1">
<div class="content">
<h4 class="title"></h4>
<iframe class="yt-video" src="https://www.youtube.com/embed/A1nRiiWYgZw" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>
<div class="black_overlay" onclick="closeLightBox()" style="display: block;">
<div style=" z-index: 0; left: 76%; top: 17%; width: 22px; position: absolute;">
<a class="close" onclick = "return close_iFrame();"><h2>×</h2></a>
</div>
</div>
</div>
[3]脚本如下：
<script>
var modal = document.getElementById('modal'),
closeBtn = modal.querySelector('close'),
ytVideo = modal.querySelector('.content .yt-video'),
title = modal.querySelector('.content .title'),
anchors = document.querySelectorAll('a[data-target="modal"]'),
l = anchors.length;
for (var i = 0; i < l; i++)
{
anchors[i].addEventListener("click", function(e)
{
e.preventDefault();
title.textContent = this.dataset.videoTitle || 'No title';
ytVideo.src = this.href;
modal.classList.toggle('is-visible');
modal.focus();
});
}
modal.addEventListener("keydown", function(e)
{
if (e.keyCode == 27)
{
title.textContent = '';
ytVideo.src = '';
this.classList.toggle('is-visible');
}
});
</script>
<script language="javascript" type="text/javascript">
function close_iFrame()
{
var modal = document.getElementById('modal'),
ytVideo = modal.querySelector('.content .yt-video');
ytVideo.src = '';
modal.classList.toggle('is-visible');
}
</script>
