jQuery UI Tabs 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 选项卡小部件用于创建单个内容区域，其中包含与列表中的标题关联的多个面板。

jQuery UI Tabs activate 事件用于在激活选项卡时触发。如果先前活动的选项卡将折叠，则 ui.oldTab 和 ui.oldPanel 将是空对象，如果选项卡正在折叠，则 ui.newTab 和 ui.newPanel 将是空 jQuery 对象。

选项卡激活事件接受下面列出的 2 个值：

event:它代表选项卡小部件的事件。
ui: 它是一个对象类型，包含以下值：
- newTab:它代表即将激活的选项卡。
- oldTab:它代表即将停用的选项卡。
- newPanel:它代表即将被激活的面板。
- oldPanel:它代表即将停用的面板。

用法:

使用 activate 回调初始化选项卡：

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

将事件监听器绑定到 tabsactivate 事件：

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