描述

當您使用標籤的 JavaScript 程式碼時，可以使用 JavaScript 事件。

示例

以下示例演示了在 Framework7 中使用標籤的 JavaScript 事件：

<!DOCTYPE html>
<html>

   <head>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1, 
         maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" />

輸出

讓我們執行以下步驟來檢視上面給出的程式碼是如何工作的：

  • 將上面給出的 HTML 程式碼儲存為tabs_js_events.html檔案，放在伺服器根目錄下。

  • 以 https:///tabs_js_events.html 的方式開啟此 HTML 檔案，輸出結果如下所示。

  • 此示例允許在標籤之間切換，並且當標籤可見時會觸發警報事件。
