我正在使用Bootstrap 5中的accordion组件，并且我想从我自己的JavaScript函数（下面的示例中的toggle）中切换该组件。最好不包含jQuery。

</head>

<body>

<button onclick="toggle(event)">Toggle Accordion Item #1</button>

<div class="accordion" id="accordionPanelsStayOpenExample">
  <div class="accordion-item">
    <h2 class="accordion-header" id="panelsStayOpen-headingOne">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#panelsStayOpen-collapseOne" aria-expanded="true" aria-controls="panelsStayOpen-collapseOne">
        Accordion Item #1
      </button>
    </h2>
    <div id="panelsStayOpen-collapseOne" class="accordion-collapse collapse show" aria-labelledby="panelsStayOpen-headingOne">
      <div class="accordion-body">
        <strong>This is the first item's accordion body.</strong> It is shown by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.

我更新了切换功能，以切换页面上的所有 accordion 。

function toggle(event)
{
    //in my sbUCR.aspx i put a button on the nav bar to call this
    //<button class="btn btn-outline" type="button" onclick="toggle(event)" id="btoggle">▲</button>
    var myCollapse2 = document.getElementsByClassName('collapse');
    for (let i = myCollapse2.length-1; i > 0; i--) //go backwards to 1 b/c 0 is the actual navbar hamburger menu
    {
        //console.log("found" + myCollapse2[i].id);
        var bsCollapse2 = new bootstrap.Collapse(myCollapse2[i], {
            toggle: true
        });
    }
}
