jQuery拖动排序插件

插件介绍

这是一款轻量级jQuery排序插件，通过拖放的方式对accordion项重新排序。

使用方法

1. 在页面中加载accordion脚本需要jqueryui的accordion组件和可排序的交互插件文件。

<link rel="stylesheet" href="jquery-ui.css" />
<script src="jquery.min.js"></script>
<script src="jquery-ui.min.js"></script>

2. 创建一个无序的accordion组件，如下所示。

<div id="accordion">
  <div class="group" data-section-id="1">
    <h3>Accordion 1</h3>
    <div>
      <ul class="sortable" data-list-id="1">
        <li data-item-id="1"><span class="draggable"></span>Item 1</li>
        <li data-item-id="2"><span class="draggable"></span>Item 2</li>
        <li data-item-id="3"><span class="draggable"></span>Item 3</li>
        ...
      </ul>
    </div>
  </div>
  <div class="group" data-section-id="2">
    <h3>Accordion 2</h3>
    <div>
      <ul class="sortable" data-list-id="2">
        <li data-item-id="11"><span class="draggable"></span>Item 11</li>
        <li data-item-id="12"><span class="draggable"></span>Item 12</li>
        <li data-item-id="13"><span class="draggable"></span>Item 13</li>
        ...
      </ul>
    </div>
  </div>
  ...
</div>

3. 初始化插件。

$("#accordion").accordion({
  header: "> div > h3",
  event: "click",
  active: false,
  collapsible: true
  // more jQuery UI Accordion options here
})

4. 创建分类。

.sortable({
  // axis: "y",
  items: "> div",
  handle: "h3",
  stop: function(e, ui) {
    var sectionList = $(this).sortable("toArray", {attribute: "data-section-id"});
    var sectionId = ui.item[0].dataset.sectionId;
    var data = JSON.stringify({sectionId, sectionList}, null, 2);
    $('.data').text(data);
    ui.item.children("h3").triggerHandler("focusout");
    $(this).accordion("refresh");
  }
});
$(".sortable").sortable({
  // axis: "y",
  items: "> li",
  handle: ".draggable",
  revert: true,
  revertDuration: 50,
  opacity: 1,
  placeholder: "ui-sortable-placeholder",
  sort: function(event, ui){ ui.item.addClass("selected"); },
  stop: function(event, ui){ ui.item.removeClass("selected"); },
  update: function(e, ui) {
    var questionList = $(this).sortable("toArray", {attribute: "data-item-id"});
    var sectionId = e.target.dataset.listId;
    var questionId = ui.item[0].dataset.itemId;
    updateData({sectionId, questionId, questionList});
  }
});

function updateData(obj) {
  var data = JSON.stringify(obj, null, 2);
  $('.data').text(data);
}

5.打印排序后的数据。

<div class="display">
  <details>
    <summary>View updated data</summary>
    <pre class="data">{}</pre>
  </details>
</div>
