嗨，我一直在努力为手风琴添加一个折叠全部，但似乎无法弄清楚..这就是我一直在使用的：https://www.w3schools.com/howto/howto_js_accordion.asp
我一直在四处寻找，但看起来这款手风琴与大多数其他手风琴不同，所以任何帮助都会非常友好。
这是我的代码：
<script>
var acc = document.getElementsByClassName("accordion");
var i;
for (i = 0; i < acc.length; i++) {
acc[i].addEventListener("click", function() {
this.classList.toggle("active");
var panel = this.nextElementSibling;
if (panel.style.maxHeight){
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight + "px";
}
});
}
</script>
CSS
.panel {
max-height: 0;
overflow: hidden;
transition: max-height 0.2s ease-in-out;
}
HTML
<article class="accordion">
<div class="info" id="more">Office 123456</div>
<div class="info" id="less">Exhibition</div>
<div class="info" id="less">2017</div>
<div class="info">Offset</div>
<div class="info">169 x 239 mm</div>
</article>
<div class="panel">
<div class="autoplay">
<div><img src="img/01.jpg" alt=""></div>
<div><img src="img/03.jpg" alt=""></div>
<div><img src="img/04.jpg" alt=""></div>
</div>
有很多方法可以实现手风琴。其中一种方法是使用Jquery UI Library。
