描述

“Selectable”函数可以与JqueryUI的交互一起使用。此函数可以在任何DOM元素上启用可选择功能。使用鼠标拖动绘制一个框来选择项目。按住Ctrl键可进行多个非相邻的选择。

语法

下面是使用”Selectable”的简单语法：

$( "#selectable" ).selectable();

示例

以下是一个简单的示例，展示了selectable的用法 –

<!doctype html>
<html lang = "en">
   <head>
      <meta charset = "utf-8">
      <title>jQuery UI Selectable - Default functionality</title>

      <link rel = "stylesheet" 
         href = "//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">

      <script type = "text/javascript" 
         src = "https://www.tutorialspoint.com/jquery/jquery-3.6.0.js">
      </script>

      <script type = "text/javascript" 
         src = "https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.3/jquery-ui.min.js">
      </script>

      <style>
         #feedback { font-size: 1.4em; }
         #selectable .ui-selecting { background: #FECA40; }
         #selectable .ui-selected { background: #F39814; color: white; }
         #selectable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
         #selectable li { margin: 3px; padding: 0.4em; font-size: 1.4em; height: 18px; }
      </style>

      <script>
          $(function() {$ ( "#selectable" ).selectable();
         });
      </script>
   </head>

   <body>

      <ol id = "selectable">
         <li class = "ui-widget-content">Item 1</li>
         <li class = "ui-widget-content">Item 2</li>
         <li class = "ui-widget-content">Item 3</li>
         <li class = "ui-widget-content">Item 4</li>
         <li class = "ui-widget-content">Item 5</li>
         <li class = "ui-widget-content">Item 6</li>
         <li class = "ui-widget-content">Item 7</li>
      </ol>

   </body>
