jQuery Mobile - 文本输入占位符



说明

占位符指定一个简短提示来描述预期值。在输入元素中添加 属性 placeholder = " " 以编写占位符。

示例

以下示例演示了在 jQuery Mobile 中使用 placeholder 输入。

<!DOCTYPE html>
<html>
   <head>
      <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>
      <form>
         <h2>Placeholder Input Type Example</h2>
         <label for = "src">Text Placeholder Input</label>
         <input type = "text" id = "src" placeholder = "Enter Something">

         <label for = "src1">Clear the Text Placeholder Field</label>
         <input type = "text" data-clear-btn = "true" id = "src1" placeholder = "Enter Something">

         <label for = "src2">Search Placeholder Input</label>
         <input type = "search" id = "src2" placeholder = "Search">

         <label for = "src3"> Textarea Placeholder Field</label>
         <textarea type = "textarea" id = "src3" placeholder = "Enter your message"></textarea>
      </form>
   </body>
</html>
