折叠全部，默认情况下仍然打开第一个手风琴

我正在尝试使用jquery手风琴。 我正在使用这个问题中的jsfiddle： jQuery UI Accordion展开/折叠全部

              try { Typekit.load(); } catch (e) { }            $(function () { $(".accordion").accordion({ collapsible: true, heightStyle: "content", active: false }); var icons = $(".accordion").accordion("option", "icons"); $('.open').click(function () { $('.ui-accordion-header').removeClass('ui-corner-all').addClass('ui-accordion-header-active ui-state-active ui-corner-top').attr({ 'aria-selected': 'true', 'tabindex': '0' }); $('.ui-accordion-header-icon').removeClass(icons.header).addClass(icons.headerSelected); $('.ui-accordion-content').addClass('ui-accordion-content-active').attr({ 'aria-expanded': 'true', 'aria-hidden': 'false' }).show(); $(this).attr("disabled", "disabled"); $('.close').removeAttr("disabled"); }); $('.close').click(function () { $('.ui-accordion-header').removeClass('ui-accordion-header-active ui-state-active ui-corner-top').addClass('ui-corner-all').attr({ 'aria-selected': 'false', 'tabindex': '-1' }); $('.ui-accordion-header-icon').removeClass(icons.headerSelected).addClass(icons.header); $('.ui-accordion-content').removeClass('ui-accordion-content-active').attr({ 'aria-expanded': 'false', 'aria-hidden': 'true' }).hide(); $(this).attr("disabled", "disabled"); $('.open').removeAttr("disabled"); }); $('.ui-accordion-header').click(function () { $('.open').removeAttr("disabled"); $('.close').removeAttr("disabled"); }); $('h1:eq(0)').trigger('click'); $('h2:eq(0)').trigger('click'); });   .accordion-expand-holder { margin: 10px 0; } .accordion-expand-holder .open, .accordion-expand-holder .close { margin: 0 10px 0 0; }

以上是我的页面看起来像。 出于某种原因，当我尝试我的小提琴时，它会做我所期待的。 但在我的代码中，这不起作用。

Answer 1

remove active:false它默认会打开第一个选项。

见DEMO

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

第二个选项， active:false 。 在代码末尾触发click事件。

  $('h3:eq(0)').trigger('click'); 

见DEMO
