jQuery UI 實例 - 選擇（Selectable）

jQuery UI選擇（Selectable）實例中，你可以使用鼠標(biāo)選擇單個元素或一組元素。

如需了解更多有關(guān)selectable交互的細(xì)節(jié)，請查看API文檔可選擇小部件（Selectable Widget）。

默認(rèn)功能

在某個DOM元素上或者一組元素上啟用selectable功能。通過鼠標(biāo)拖拽選擇條目。按住Ctrl鍵，選擇多個不相鄰的條目。

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

<body>
 
<ol id="selectable">

  <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>

顯示為網(wǎng)格

讓selectable條目顯示為網(wǎng)格，使用CSS使得它們帶有相同的尺寸且浮動顯示。

  </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">11</li>
  <li class="ui-state-default">12</li>
</ol>

序列化

寫一個函數(shù)，在stop事件發(fā)生時觸發(fā)，來收集被選中條目的索引值。呈現(xiàn)這些值作為反饋，或者以數(shù)據(jù)字符串形式進(jìn)行傳遞。
