javascript - 防止元素收缩
问题描述
我正在尝试在我的网站上对这个发现菜单部分进行编码，除了一件事，当我单击View more按钮时 Js 被激活但项目缩小，我不知道为什么我试图将宽度设置为100％，但它不起作用。我在这里搜索了一点堆栈溢出但我没有发现任何有用的东西是我的代码：
.discover-ou-menu{
position: relative;
}
.section-heading{
text-align: center;
font-family: 'Roboto', sans-serif;
text-transform:capitalize;
margin: 0;
}
.section-heading::after{

解决方案
只需在主元素和第 n 个子元素上使用一个类来隐藏它而不是包装它们。
document.querySelector("button").addEventListener("click", function () {
document.querySelector('.table').classList.toggle('limited');
}).table.limited .tr:nth-of-type(1n+4) {display: none;}<div class="table limited">
<div class="tr">1
</div>
<div class="tr">2
</div>
<div class="tr">3
</div>
<div class="tr">4
</div>
<div class="tr">5
</div>
<div class="tr">6
</div>
</div>
<button class="more">more</button>带动画
document.querySelector("button").addEventListener("click", function() {
document.querySelector('.table').classList.toggle('limited');
}).table.limited .tr:nth-of-type(1n+4) {
max-height: 0;
overflow: hidden;
opacity: 0;
}
.table .tr:nth-of-type(1n+4) {
opacity: 1;
transition: all 1s ease-in;
max-height: 100em;
}<div class="table limited">
<div class="tr">1
</div>
<div class="tr">2
</div>
<div class="tr">3
</div>
<div class="tr">4
</div>
<div class="tr">5

<div class="tr">6

</div>
<button class="more">more</button>推荐阅读
