jQuery UI 实例 - 选择(Selectable)

jQuery UI选择(Selectable)实例中,你可以使用鼠标选择单个元素或一组元素。

如需了解更多有关selectable交互的细节,请查看API文档可选择小部件(Selectable Widget)

默认功能

在某个DOM元素上或者一组元素上启用selectable功能。通过鼠标拖拽选择条目。按住Ctrl键,选择多个不相邻的条目。

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">

  <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >

  <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>
</html>

显示为网格

让selectable条目显示为网格,使用CSS使得它们带有相同的尺寸且浮动显示。

  <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: 450px; }
  #selectable li { margin: 3px; padding: 1px; float: left; width: 100px; height: 80px; font-size: 4em; text-align: center; }
  </style>
  <script>
  $(function() {
    $( "#selectable" ).selectable();
  });
  </script>
</head>
<body>
 
<ol id="selectable">
  <li class="ui-state-default">1</li>
  <li class="ui-state-default">2</li>
  <li class="ui-state-default">3</li>
  <li class="ui-state-default">4</li>
  <li class="ui-state-default">5</li>
  <li class="ui-state-default">6</li>
  <li class="ui-state-default">7</li>
  <li class="ui-state-default">8</li>
  <li class="ui-state-default">9</li>
  <li class="ui-state-default">10</li>
  <li class="ui-state-default">11</li>
  <li class="ui-state-default">12</li>
</ol>
 
 
</body>
</html>

序列化

写一个函数,在stop事件发生时触发,来收集被选中条目的索引值。呈现这些值作为反馈,或者以数据字符串形式进行传递。

  #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({
      stop: function() {
        var result = $( "#select-result" ).empty();
        $( ".ui-selected", this ).each(function() {
          var index = $( "#selectable li" ).index( this );
          result.append( " #" + ( index + 1 ) );
        });
      }
    });
  });
  </script>
</head>
<body>
 
<p id="feedback">
<span>您已经选择了:</span> <span id="select-result">无</span>。
</p>
 
<ol id="selectable">
