Question

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

但我不明白如何在此代码中执行data-collapsed =“false”，这是我的完整代码：

<!DOCTYPE html>

        });
    });
    </script>

问题是我每次只是重新加载它显示的页面：

但是想要这样： enter image description here

请帮帮我，谢谢你。

您根本不需要修改任何HTML，因为jQueryUI accordion具有0属性来确定在加载时展开哪个面板。默认情况下，它是false - 第一个面板。将其设置为$("#accordion").accordion({ collapsible: true, active: false });以默认全部折叠：

[<NamedUnionCases "Icon">]
type IconName =
    | Aaabattery
    | Abacus

[<NamedUnionCases>]
type Size =
    | H1
    | H2
    | H3
    | H4
    | H5


type Icon = {title:string; name:IconName; size:Size; updated:DateTime; }


Icon {title = "hello";
  name = Aaabattery;
  size = H1;
  updated = 11/06/2015 3:18:29 p. m.;}
