jQuery UI Accordion create事件

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非常适合为网页建立UI界面。jQuery UI Accordion Widget可用于将成对的标题和内容面板转换为一个手风琴。

jQuery UI Accordion create事件是用来在手风琴被创建时触发的。如果一个手风琴部件被折叠，那么ui.header和ui.panel将是空对象。Accordion创建事件接受2个值，如下所示。

event。它代表滑块小部件的事件。
ui。它是一个对象类型，并包含以下值。
- header。它代表活动的头。
- panel。它代表活动面板。

语法:

用create回调初始化口风琴。

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

为accordioncreate事件绑定一个事件监听器。

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