jQuery UI Accordion activate用法及代码示例

jQuery UI 由 GUI 小部件、视觉效果和使用 HTML、CSS 和 jQuery 实现的主题组成。 jQuery UI 非常适合为网页构建 UI 接口。 jQuery UI selectmenu 小部件可以为我们提供选择选项。我们可以使用这个小部件来为不同的操作制作一个表单。

jQuery UI Accordion activate 事件用于在激活折叠面板后触发。

Accordion activate 事件接受下面列出的两个值：

event:它代表滑块小部件的事件。
ui:它是一个对象类型值。它包含四种类型的属性，如下所示：
- newHeader:它代表刚刚激活的标头。
- oldHeader:它代表刚刚停用的标头。
- newPanel:它代表刚刚激活的面板。
- oldPanel:它代表刚刚停用的面板。

用法:

使用 activate 回调初始化手风琴：

$( ".selector" ).accordion({
  activate: function( event, ui ) {}
});

将事件侦听器绑定到手风琴激活事件：

$( ".selector" ).on( 
    "accordionactivate", 
    function( event, ui ) {} 
);
