问下如何实现类似这个评论区打开的时候这个视屏会自动缩小而不是被评论区挡住
<div class="box">
<div id="box1"><input type="button" id="btn" value="隐藏">顶部盒子</div>
<div id="box2">内容区域</div>
<div id="box3">底部盒子</div>
<div id="box4">显示盒子</div>
</div>
.box {
margin: auto;
width: 100%;
height: 100%;
background-color: beige;
position: relative;
}
#box1 {
width: 100%;
height: 100px;
background-color: aqua;
}
#box2 {
width: 100%;
height: 550px;
background-color: antiquewhite;
}
#box3 {
width: 100%;
height: 150px;
background-color: pink;
}
#box4 {
width: 100px;
height: 100%;
background-color: chartreuse;
float: left;
position: absolute;
top: 0;
z-index: 1;
}
#btn {
float: right;
}
.show {
display: block;
}
.hidden {
display: none;
}
var btn = document.getElementById('btn');
var isShow = true;
btn.onclick = function () {
var box4 = document.getElementById('box4')
if (isShow) {
box4.className = 'hidden'
btn.value = '显示';
isShow = false;
}
else {
box4.className = 'show'
btn.value = '隐藏';
isShow = true
}
}

<div class="box">
<div id="box1">
<input type="button" id="btn" value="隐藏">顶部盒子
</div>
<div id="box2">内容区域</div>
<div id="box3">底部盒子</div>
<div id="box4">显示盒子</div>
</div>
.box {
margin: auto;
width: 100%;
height: 100%;
background-color: beige;
position: relative;
}
#box1 {
width: 100%;
height: 100px;
background-color: aqua;
}
#box2 {
width: 100%;
height: 550px;
background-color: antiquewhite;
z-index: 0; /* 该行代码用于设置box2的宽度变化时不会被box4挡住 */
}
#box3 {
width: 100%;
height: 150px;
background-color: pink;
}
#box4 {
width: 100px;
height: 100%;
background-color: chartreuse;
float: left;
position: absolute;
top: 0;
z-index: 1;
}
#btn {
float: right;
}
<script>
var box2 = document.getElementById('box2');
var box4 = document.getElementById('box4');
document.getElementById('btn').addEventListener('click', function() {
if (box2.style.width === '100%') {
box2.style.width = 'calc(100% - 100px)';
box4.style.display = 'none';
} else {
box2.style.width = '100%';
box4.style.display = 'block';
}
});
</script>
以上代码通过设置box2的z-index属性使其能够在宽度变化时不被box4挡住。代码已经可以实现自动缩小和展开,但是如果要实现在评论区域打开时才触发自动缩小,还需要进一步修改代码。假设评论区域有一个id为comment的元素。
<div class="box">
<div id="box1">
<input type="button" id="btn" value="隐藏">顶部盒子
</div>
<div id="box2">内容区域</div>
<div id="box3">底部盒子</div>
<div id="box4">显示盒子</div>
</div>
<div id="comment">
评论区域
</div>
可以通过监听评论区域的点击事件来触发自动缩小和展开。
<script>
var box2 = document.getElementById('box2');
var box4 = document.getElementById('box4');
var comment = document.getElementById('comment');
comment.addEventListener('click', function() {
if (box2.style.width === '100%') {
box2.style.width = 'calc(100% - 100px)';
box4.style.display = 'none';
} else {
box2.style.width = '100%';
box4.style.display = 'block';
}
});
document.getElementById('btn').addEventListener('click', function() {
if (box2.style.width === '100%') {
box2.style.width = 'calc(100% - 100px)';
box4.style.display = 'none';
} else {
box2.style.width = '100%';
box4.style.display = 'block';
}
});
</script>
这样在点击评论区域时也会触发自动缩小和展开的效果。你可以根据实际需求修改代码和样式,达到你想要的效果。

使用flex布局,设置video容器为自适应,video设置aspect-ratio保持横纵比不变。
