【问题描述】：

我希望在 Foundation 6 中为手风琴实现“全部展开/全部折叠”链接。如需参考，请参阅此codepen。

$(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');
  }
     
});

（单独的“全部展开”和“全部折叠”链接也可以。）

也是一种实现滚动到打开/活动手风琴顶部的方法。

任何帮助将不胜感激。

谢谢。

【解决方案1】：

初始化你的手风琴后，你可以用这些函数来实现它：

// open all panels
$('#yourAccordion').foundation('down', $('#yourAccordion .accordion-content'));
// close all panels
$('#yourAccordion').foundation('up', $('#yourAccordion .accordion-content'));

现在您只需要一个点击处理程序和一个可供点击的按钮/链接。

// HTML
<button id="#close" type="button">Collapse all</button>
<button id="#open" type="button">Expand all</button>

如果您希望使用链接，请不要忘记在点击处理程序中添加 preventDefault() 和 return。

// js
$('#close').on('click', function () {
    $('#yourAccordion').foundation('up', $('#yourAccordion .accordion-content'));
})


$('#open').on('click', function () {
    $('#yourAccordion').foundation('down', $('#yourAccordion .accordion-content'));
})
