我在这里找到了这段代码:https://jqueryui.com/accordion/#collapsible

最佳答案
您根本不需要修改任何 HTML，因为 jQueryUI 折叠面板具有 active 属性来确定加载时要展开的面板。默认情况下它是 0 - 第一个面板。将此设置为 false 以默认折叠所有内容:
$("#accordion").accordion({
collapsible: true,
active: false
});
关于javascript - 我如何在此代码中折叠 ="false"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30784852/
