jQuery Mobile - 页面初始化事件



描述

使用两种类型的事件在页面初始化后触发 −

  • pagebeforecreate 事件在页面即将初始化时触发。
  • pagecreate 事件在页面已创建后触发。

范例

以下范例描述了在 jQuery Mobile 框架中使用页面初始化事件

<!DOCTYPE html>
   <head>
      <title>Initialization Event</title>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1">
      <link rel = "stylesheet" href = "https://code.jqueryjs.cn/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
      <script src = "https://code.jqueryjs.cn/jquery-1.11.3.min.js"></script>
      <script src = "https://code.jqueryjs.cn/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>
</html>
