Question

我想在重新排序列表并重新加载页面后保存这些列表。我可以通过srtable jquery移动列表但我无法将这些保存到codeigniter中的数据库中。下面是View部分的代码。

查看：

$(function() {
    $( "#sortable" ).sortable({
      revert: true
    });
    $( "#draggable" ).draggable({
      connectToSortable: "#sortable",
      helper: "clone",
      revert: "invalid"
    });
    $( "ul, li" ).disableSelection();
  });

 ul { list-style-type: none; margin: 0; padding: 0; margin-bottom: 10px; }
  li { margin: 5px; padding: 5px; width: 150px; }

<head>
  <meta charset="utf-8">
  <title>jQuery UI Draggable + Sortable</title>
  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
  <script src="//code.jquery.com/jquery-1.10.2.js"></script>
  <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
  <link rel="stylesheet" href="/resources/demos/style.css">
  
<ul id="sortable">
  <li class="ui-state-default">Item 1</li>
  <li class="ui-state-default">Item 2</li>
  <li class="ui-state-default">Item 3</li>
  <li class="ui-state-default">Item 4</li>
  <li class="ui-state-default">Item 5</li>
</ul>

使用update选项添加一个回调，然后调用更新数据库所需的任何ajax。

＆＃13;

$(function() {
    $( "#sortable" ).sortable({
      revert: true,
      update: function( event, ui ) {
        alert('make your call to whatever controller via ajax here')
      }
    });
    $( "#draggable" ).draggable({
      connectToSortable: "#sortable",
      helper: "clone",
      revert: "invalid"
    });
    $( "ul, li" ).disableSelection();
  });

＆＃13;

ul { list-style-type: none; margin: 0; padding: 0; margin-bottom: 10px; }
  li { margin: 5px; padding: 5px; width: 150px; }

  <li class="ui-state-default">Item 4</li>

</ul>
