我正在尝试创建一个类似于此的youtube模式:
https://www.udacity.com/但是在使用视觉作曲家的wordpress中.
我对这个模态有3个问题:
1 – 单击时背景图层不会覆盖顶部导航菜单内容,它们仍会显示.如何强制背景拉伸并覆盖菜单?
2 – 滚动条被隐藏但用户仍然可以向下滚动滚轮,页面下方的一些元素显示在弹出层的顶部
3-最大的问题在于关闭视频并使弹出图层响应.原始代码有固定的大小,我改为百分比并使其工作,但在移动设备中看起来很奇怪

使用Javascript:
<script type="text/javascript">
function onYouTubeIframeAPIReady() {
player = new YT.Player('video-placeholder', {
width: 1180,
height: 664,
videoId: 'gZC1TOLVi60',
events: {
onReady: initialize
}
});
}
function initialize(){
}
function deployVideo() {
jQuery('.mm-product-video-modal-container').addClass('open');
setTimeout(function() {
jQuery('.mm-product-video-modal').addClass('open');
player.playVideo();
}, 250);
}
function destroyVideo() {
jQuery('.mm-product-video-modal').removeClass('open');
setTimeout(function() {
jQuery('.mm-product-video-modal-container').removeClass('open');
player.pauseVideo();
}, 250);
}
jQuery('.mm-video-overlay').on('click', function() {
destroyVideo();
});
jQuery('.mm-launch').on('click',function() {
deployVideo();
});
</script>
HTML:
<script src="https://www.youtube.com/iframe_api"></script>
<div align="center" class="mm-product-video-modal-container">
<div class="mm-product-video-modal dropper">
<div class="embed-responsive embed-responsive-16by9">
<div id="video-placeholder"></div>
</div>
</div>
<div class="mm-video-overlay"></div>
</div>
<div class="mm-launch-container container" align="center">
<div class="col-sm-offset-3 col-sm-6">
<button class="mm-launch">Launch Video</button>
</div>
</div>
最佳答案 对于问题1:
您需要将标题z-index设置为较低的值,然后设置为叠加层.
在样式中添加以下css类以覆盖标头z-index.
header{
z-index:1 !important;
}
同时将css类mm-video-overlay的z-index调整为1001
.mm-video-overlay {
position: fixed;
top: 0px;
left: 0px;
background: transparent;
width: 100%;
height: 100%;
z-index: 1001;
}
对于问题2:
您需要使用属性overflow:在显示播放器叠加层时隐藏在主体上,然后在关闭视频叠加层时将其删除.
在js中使用的代码:
function deployVideo() {
jQuery('.mm-product-video-modal-container').addClass('open');
setTimeout(function() {
jQuery('.mm-product-video-modal').addClass('open');
player.playVideo();
}, 250);
jQuery('body').css('overflow','hidden');
}
function destroyVideo() {
jQuery('.mm-product-video-modal').removeClass('open');
setTimeout(function() {
jQuery('.mm-product-video-modal-container').removeClass('open');
player.pauseVideo();
}, 250);
jQuery('body').css('overflow','');
}
这将处理滚动问题
对于问题3:
将top属性设置为css类mm-product-video-modal.open的百分比为15%
.mm-product-video-modal.open {
top: 15%;
margin-bottom: 150px;
}
