jQuery Mobile - 頁面初始化事件

描述

使用兩種型別的事件在頁面初始化後觸發 −

pagebeforecreate 事件在頁面即將初始化時觸發。
pagecreate 事件在頁面已建立後觸發。

範例

以下範例描述了在 jQuery Mobile 框架中使用頁面初始化事件。

<!DOCTYPE html>
   <head>
      <title>Initialization Event</title>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1">
      <link rel = "stylesheet" href = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
      <script src = "https://code.jquery.com/jquery-1.11.3.min.js"></script>
      <script src = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
      
      <script>
         $(document).on("pagebeforecreate",function() {
            alert("The pagebeforecreate event has been fired and the page is not yet initialized.");
         });
         $(document).on("pagecreate",function() {
            alert("The pagecreate event has been fired and and the page has been created.");
         });
      </script>
   </head>
   
   <body>
      <div data-role = "page" id = "page1"> 
         <div data-role = "header">
            <h2>Header</h2>
         </div>

         <div data-role = "main" class = "ui-content">
            <p>The page has been initialized.</p>
         </div>

         <div data-role = "footer">
            <h2>Footer</h2>
         </div>
      
      </div>
   </body>
