我对jQuery很新，但我真的很喜欢它能做什么，我正在取得良好进展，但是当我按下播放时我无法打开div。
我不想在这个项目中使用Bootstrap模态。我想要的是打开视频作为视口宽度和高度的全宽和高度。
目前它没有播放，这是我的codepen，我的代码在下面。
作为一个例子，我希望在按下播放时实现类似this的内容。
$(document).ready(function(){
$(".glyphicon-play-circle").click(function(){
$(".movie").css("display","block")
})
})
CSS
.movie{
display:none;
position:absolute;
z-index:1;
top:0;
width:100%;
height:100vh;
background:black;
}
答案 0 :(得分：1)
我对您的代码进行了更改。我禁用了全屏内容，因为它足以让一个视频变满。不需要额外的视频就可以了。
$(document).ready(function() {
$(".glyphicon-play-circle").click(function() {
$(".movie").css("display", "block")
$("#bgvid").toggleClass("is-not-active");
$(".fullscreen").toggleClass("is-video-active");
$(".fullscreen.is-video-active").prop("autoplay", true);
});
});* {
box-sizing: border-box;
;
}

html {
height: 100%;

.logo {
float: left;
width: 50%;
