Question

我当前正在设置一个常见问题页面，并且我需要添加一个功能来单击按钮来扩展/折叠所有答案。如果单击扩展链接/按钮，它将显示手风琴的所有内容，然后将标签“全部扩展”替换为“全部折叠”，反之亦然。

我不确定是否可以调整当前的JS。

//hides a accordion panel
function close(opts) {
    opened = $(document).find('.' + opts.cssOpen);
    $.each(opened, function() {
        //give the proper class to the linked element
        $(this).addClass(opts.cssClose).removeClass(opts.cssOpen);
        opts.animateClose($(this), opts);
    });
}

//opens a accordion panel
function open($this, opts) {
    close(opts);
    //give the proper class to the linked element
    $this.removeClass(opts.cssClose).addClass(opts.cssOpen);

    //open the element
    opts.animateOpen($this, opts);

    //do cookies if plugin available
    if (useCookies(opts)) {
        // split the cookieOpen string by ","
        id = $this.attr('id');
        setCookie(id, opts);
    }
}

//toggle a accordion on an event
function toggle($this, opts) {
    // close the only open item
    if ($this.hasClass(opts.cssOpen))
    {
        close(opts);
        //do cookies if plugin available
        if (useCookies(opts)) {
            // split the cookieOpen string by ","
            setCookie('', opts);
        }
        return false;
    }
    close(opts);
    //open a closed element
    open($this, opts);
    return false;
}

您可以使用下面的jquery和bootstrap代码获得相同的功能：

html代码

<div class="container">
  <div class="accordion-option">
    <h3 class="title">Lorem Ipsum</h3>
    <a href="javascript:void(0)" class="toggle-accordion active" accordion-id="#accordion"></a>
  </div>
  <div class="clearfix"></div>
  <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
    <div class="panel panel-default">
      <div class="panel-heading" role="tab" id="headingOne">
        <h4 class="panel-title">
        <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </a>
      </h4>
      </div>
      <div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne">
        <div class="panel-body">
          labore sustainable VHS.
        </div>
      </div>
    </div>
    <div class="panel panel-default">
      <div class="panel-heading" role="tab" id="headingTwo">
        <h4 class="panel-title">
        <a class="collapsed" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo" aria-expanded="true" aria-controls="collapseTwo">
          Collapsible Group Item #2
        </a>
      </h4>
      </div>
      <div id="collapseTwo" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingTwo">
        <div class="panel-body">
          Anim pariatur cliche reprehenderit,
        </div>
      </div>
    </div>
    <div class="panel panel-default">
      <div class="panel-heading" role="tab" id="headingThree">
        <h4 class="panel-title">
        <a class="collapsed" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseThree" aria-expanded="true" aria-controls="collapseThree">
          Collapsible Group Item #3
        </a>
      </h4>
      </div>
      <div id="collapseThree" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingThree">
        <div class="panel-body">
          Anim pariatur cliche reprehenderit
        </div>
      </div>
    </div>
  </div>
</div>

Css代码：

body {
  color: #6a6c6f;
  background-color: #f1f3f6;
  margin-top: 30px;
}

.container {
  max-width: 960px;
}

.panel-default>.panel-heading {
  color: #333;
  background-color: #fff;
  border-color: #e4e5e7;
  padding: 0;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

.panel-default>.panel-heading a {
  display: block;
  padding: 10px 15px;
}

.panel-default>.panel-heading a:after {
  content: "";
  position: relative;
  top: 1px;
  display: inline-block;
  font-family: 'Glyphicons Halflings';
  font-style: normal;
  font-weight: 400;
  line-height: 1;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  float: right;
  transition: transform .25s linear;
  -webkit-transition: -webkit-transform .25s linear;
}

.panel-default>.panel-heading a[aria-expanded="true"] {
  background-color: #eee;
}

.panel-default>.panel-heading a[aria-expanded="true"]:after {
  content: "\2212";
  -webkit-transform: rotate(180deg);
  transform: rotate(180deg);
}

.panel-default>.panel-heading a[aria-expanded="false"]:after {
  content: "\002b";
  -webkit-transform: rotate(90deg);
  transform: rotate(90deg);
}

.accordion-option {
  width: 100%;
  float: left;
  clear: both;
  margin: 15px 0;
}

.accordion-option .title {
  font-size: 20px;
  font-weight: bold;
  float: left;
  padding: 0;
  margin: 0;
}

.accordion-option .toggle-accordion {
  float: right;
  font-size: 16px;
  color: #6a6c6f;
}

.accordion-option .toggle-accordion:before {
  content: "Expand All";
}

.accordion-option .toggle-accordion.active:before {
  content: "Collapse All";
}

JavaScript代码：

$(document).ready(function() {

  $(".toggle-accordion").on("click", function() {
    var accordionId = $(this).attr("accordion-id"),
      numPanelOpen = $(accordionId + ' .collapse.in').length;

    $(this).toggleClass("active");

    if (numPanelOpen == 0) {
      openAllPanels(accordionId);
    } else {
      closeAllPanels(accordionId);
    }
  })

  openAllPanels = function(aId) {
    console.log("setAllPanelOpen");
    $(aId + ' .panel-collapse:not(".in")').collapse('show');
  }
  closeAllPanels = function(aId) {
    console.log("setAllPanelclose");
    $(aId + ' .panel-collapse.in').collapse('hide');
  }

});

对于给定的代码，您必须使用bootstarp 3.3.6，这些代码在我使用过引导程序3.3.6的旧项目中使用，或者您可以为引导程序4进行修改。

引导CSS链接：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

jQuery和bootstrap js链接

<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

是否可以添加功能来在单击中扩展和/或折叠所有手风琴？
