Framework7 - 状态栏

描述

iOS 7+ 允许您构建全屏应用，但当您的状态栏与应用重叠时，可能会出现问题。Framework7 通过检测您的应用是否处于全屏模式来解决此问题。如果您的应用处于全屏模式，则 Framework7 会自动将 with-statusbar-overlay 类添加到 <html>(如果应用未处于全屏模式，则删除)，您需要在 <body> 中添加 statusbar-overlay 类，如以下代码所示 −

<html class = "with-statusbar-overlay">
...
   <body>
      <div class = "statusbar-overlay"></div>
      ...

默认情况下，<div> 将始终隐藏并固定在屏幕顶部。只有当应用处于全屏模式并且将 with-statusbar-overlay 类添加到 <html> 时，它才会可见。

示例

以下示例演示了 Framework7 中状态栏的使用 −

<!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" />
      <meta name = "apple-mobile-web-app-capable" content = "yes" />
      <meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
      <title>My App</title>
      <link rel = "stylesheet" 
         href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />
      <link rel = "stylesheet" 
         href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.colors.min.css" />
   </head>

   <body>
      <div class = "statusbar-overlay"></div>
      <div class = "panel-overlay"></div>
      
      <div class = "panel panel-right panel-reveal">
         <div class = "content-block">
            <p>Contents goes here...</p>
         </div>
      </div>
      
      <div class = "views">
         <div class = "view view-main">
            <div class = "navbar">
               <div class = "navbar-inner">
                  <div class = "center sliding">My App</div>
                  
                  <div class = "right">
                     <a href = "#" class = "link icon-only open-panel"><i class = "icon icon-bars"></i></a>
                  </div>
                  
               </div>
            </div>
            
            <div class = "pages navbar-through toolbar-through">
               <div data-page = "index" class = "page">
                  <div class = "page-content">
                     <p>This is simple application...</p>
                     <p>page contents goes here!!!</p>
                  </div>
               </div>
            </div>
            
            <div class = "toolbar">
               <div class = "toolbar-inner">
                  <a href = "#" class = "link">First Link</a>
                  <a href = "#" class = "link">Second Link</a>
               </div>
            </div>
            
         </div>
      </div>
      
      <script type = "text/javascript" 
         src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"></script>
      
      <script>
         // 此处初始化应用程序
         var myApp = new Framework7();

         // 如果您使用自定义 DOM 库，则将其保存到 $$ 变量
         var $$ = Dom7;

         // 添加视图
         var mainView = myApp.addView('.view-main', {
            // 为该视图启用动态导航栏:
            dynamicNavbar: true
         });

         //use the 'pageInit' event handler for all pages
         $$(document).on('pageInit', function (e) {
            //get page data from event data
            var page = e.detail.page;
         })
      </script>
   </body>

</html>

输出

让我们执行以下步骤来查看上述代码的工作原理 −

• 将上述 html 代码保存为服务器根文件夹中的 status_bar.html 文件。

• 以 http://localhost/status_bar.html 的形式打开此 HTML 文件，输出显示如下。

该示例展示了 statusbar-overlay 的使用，它允许您在状态栏与应用程序重叠时构建全屏应用程序。
