Question

我通常从以下位置获取代码：https://www.w3schools.com。该代码也有一个手风琴。

但是，当我使用链接->到手风琴时，它不会跳开而是保持关闭状态。如果有人链接了在手风琴内部具有内容的链接，是否有人知道如何打开手风琴。

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";
    }
  }
}

我在理解您最初的要求时遇到了一些麻烦，但无论如何我还是一口气！

向.accordion按钮添加ID。为文本链接添加了.accordion-link类。单击手风琴链接时，哈希被隔离，并用于触发具有相应ID的手风琴按钮上的click事件。

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">

</div>

编辑-我还从您的按钮中删除了链接标签...不确定按钮中是否允许使用标签，或者不确定是否在我的头顶上方，但是感觉不对，所以我将其编成辫子。

使用<a href="#link.html">link</a>和<a name="link"></a>时打开手风琴
