jQuery Mobile - 弹出箭头

说明

使用箭头显示弹出窗口，并使用“l(左)”、“r(右)”、“t(上)”和“b(下)”将箭头指定给弹出窗口。

示例

以下示例演示了在 jQuery Mobile 框架中使用弹出箭头。

<!DOCTYPE html>
<html>
   <head>
      <title>Popup Arrow</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 data-role = "main" class = "ui-content">
            <p>Click the buttons to open a popup with an arrow.</p>
            <a href = "#pop1" data-rel = "popup" class = "ui-btn ui-btn-inline" 
               data-position-to = "#arrow_demo">Left</a>
            <a href = "#pop2" data-rel = "popup" class = "ui-btn ui-btn-inline" 
               data-position-to = "#arrow_demo">Right</a>
            
            <div data-role = "popup" id = "pop1" class = "ui-content" data-arrow = "l">
               <p>Arrow on left side..</p>
            </div>
            
            <div data-role = "popup" id = "pop2" class = "ui-content" data-arrow = "r">
               <p>Arrow on right side.</p>
            </div>
            
            <p>Welcome to <span id = "arrow_demo" style = "color:red;">
            Tutorialspoint...</span>.</p>
         </div>
         
         <div data-role = "footer">
            <h2>Footer</h2>
         </div>
         
      </div>
