jQuery UI Tabs activate用法及代碼示例

jQuery UI 由 GUI 小部件、視覺效果和使用 HTML、CSS 和 jQuery 實現的主題組成。 jQuery UI 非常適合為網頁構建 UI 接口。 jQuery UI 選項卡小部件用於創建單個內容區域，其中包含與列表中的標題關聯的多個麵板。

jQuery UI Tabs activate 事件用於在激活選項卡時觸發。如果先前活動的選項卡將折疊，則 ui.oldTab 和 ui.oldPanel 將是空對象，如果選項卡正在折疊，則 ui.newTab 和 ui.newPanel 將是空 jQuery 對象。

選項卡激活事件接受下麵列出的 2 個值：

event:它代表選項卡小部件的事件。
ui: 它是一個對象類型，包含以下值：
- newTab:它代表即將激活的選項卡。
- oldTab:它代表即將停用的選項卡。
- newPanel:它代表即將被激活的麵板。
- oldPanel:它代表即將停用的麵板。

用法:

使用 activate 回調初始化選項卡：

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

將事件監聽器綁定到 tabsactivate 事件：

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