javascript - jquery ui Accordion 单击一次展开但第二次单击不折叠

Question

我在点击它展开(打开)时有 Accordion ，但是当我再次点击它时它没有关闭 Accordion 。如何更改功能，以便在我第二次单击 Accordion 时可以关闭 Accordion 。

$(function() {
  var icons = {
    header: "ui-icon-circle-arrow-e",
    activeHeader: "ui-icon-circle-arrow-s"
  };
  $("#accordion").accordion({
    icons: icons
  });
  $("#toggle").button().on("click", function() {
    if ($("#accordion").accordion("option", "icons")) {
      $("#accordion").accordion("option", "icons", null);
    } else {
      $("#accordion").accordion("option", "icons", icons);
    }
  });
});

快速修复，在 Accordion 选项中设置 collapsible:true。例如

$("#accordion").accordion({
   collapsible: true
});
