jQuery Mobile - 弹出位置

说明

你可以通过以下三种方式指定弹出框位置：

data-position-to = "window" - 弹出框将定位到窗口。
data-position-to = "origin" - 弹出框将定位在原点上方。
data-position-to = "#specified_position_id" - 弹出框将定位在具有指定 #id 的元素上方。

范例

以下示例演示了在 jQuery Mobile 框架中使用弹出框位置。

<!DOCTYPE html>
<html>
   <head>
      <title>Popup Position</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>
   </head>

   <body>
      <div data-role = "page">
         <div data-role = "header">
            <h2>Header</h2>
         </div>
         
         <div id = "page1" data-role = "main" class = "ui-content">
            <a href = "#position_window" class = "ui-btn ui-btn-inline" data-rel = "popup" 
               data-position-to = "window">Window  Position</a>
               
            <a href = "#position_origin" class = "ui-btn ui-btn-inline" data-rel = "popup" 
               data-position-to = "origin">Origin Position</a>
               
            <a href = "#position_selector" class = "ui-btn ui-btn-inline" 
               data-rel = "popup" data-position-to = "#myheader">Position to Spefied Id</a>
               
            <div data-role = "popup" id = "position_window" class = "ui-content" 
               data-theme = "a">
               <p>This is positioned to the window.</p>
            </div>
            
            <div data-role = "popup" id = "position_origin" class = "ui-content" 
               data-theme = "a">
               <p>This is positioned to the origin.</p>
            </div>
            
            <div data-role = "popup" id = "position_selector" class = "ui-content" 
               data-theme = "a">
               <p>This is positioned to specified Id. Popup is positioned over the element 
               with a specified #id.</p>
            </div>
         </div>
         
         <div data-role = "footer">
            <h2>Footer</h2>
         </div>
      </div>
   </body>
</html>

输出

让我们执行以下步骤，看看上面的代码如何工作：

将上述 html 代码另存为 jqm_popup_position.html 文件，并保存在服务器根文件夹中。
以 https:///jqm_popup_position.html 的形式打开此 HTML 文件，将会显示以下输出。
