javascript - 使用 link & 打开 Accordion

Question

我通常从以下位置获取代码:https://www.w3schools.com .这个代码还有一个 Accordion ；

但是，当我使用链接 -> 到 Accordion 时， Accordion 不会跳开，而是保持关闭状态。如果有人链接了一个包含 Accordion 内容的链接，有人知道如何打开 Accordion 吗？

谢谢。

var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].onclick = function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight){
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    }
  }
}

 /* Style the buttons that are used to open and close the accordion panel */
button.accordion {
    background-color: #530010;
    color: #FFF;
	font-weight: bolder;
    cursor: pointer;
    padding: 10px;
    width: 100%;
    text-align: left;
    border: none;
    outline: none;
    transition: 0.4s;
	border-radius: 5px;
}

/* Add a background color to the button if it is clicked on (add the .active class with JS), and when you move the mouse over it (hover) */
button.accordion.active, button.accordion:hover {
    background-color: #a20121;
}

/* Style the accordion panel. Note: hidden by default */
div.panel {
    padding: 0px 5px;    
	margin-bottom: 5px;
	background-color: #none;
    max-height: 0px;
    overflow: hidden;
    transition: max-height 0.2s ease-out;
}

button.accordion:after {
    content: '\02795'; /* Unicode character for "plus" sign (+) */
    font-size: 13px;
    color: #FFF;
	font-weight: bolder;
    float: right;
    margin-left: 5px;
}

button.accordion.active:after {
    content: "\2796"; /* Unicode character for "minus" sign (-) */
}

最初我有点难以理解您的问题，但我还是试了一下!

为 .accordion 按钮添加了 ID。为文本链接添加了 .accordion-link 类。当点击 Accordion 链接时，哈希被隔离，并用于触发具有相应 ID 的 Accordion 按钮上的点击事件。

fiddle :https://jsfiddle.net/ya6vtosc/25/

JS

var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].onclick = function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight){
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    }
  }
}

// get list of links by class
var links = document.getElementsByClassName("accordion-link");

var linksLength = links.length;
for(var i=0; i < linksLength; i++){
  links[i].onclick = function(e){
    // preventDefault is probably optional
    // depending on your application
    e.preventDefault();

    // isolate the hash
    var hash = e.path[0].hash;

    // remove # from hash
    hash = hash.substring(1, hash.length);

    // select by id using hash
    document.getElementById(hash).click();
  }

HTML

<a href="schedule.html#0906" class="accordion-link">2018.09.06</a>(木) 今池GROW<br><br>


<button class="accordion" id="0906">2018/09/06(木)今池GROW </button>
<div class="panel">

编辑 - 我还从您的按钮中删除了您的链接标签...不确定标签是否允许在按钮中使用或不在我的脑海中，但感觉不对所以我放弃了它们。
