js源码

$(function(){
    $('.btn.remove').click(function(){
        if(confirm("确定要删除页面吗？")) {
            $(this).parent().detach();
        }
    });
    var dropable = $('#dropzone').droppable({
        activeClass : 'active',
        hoverClass : 'hover',
        accept : ":not(.ui-sortable-helper)"
    });
    dropable.sortable({
        items : '.drop-item',
        sort : function() {
            $(this).removeClass("active");
        }
    });
    $('#report_page_save_btn').click(function(){
        save();
    });
    $('#report_page_def_btn').click(function(){
        if(confirm("确定要恢复页面数据吗？")) {
            set_def();
        }
    });
    
});

 

使用其他第三方js结构如下。其实就只有使用了jquery-ui

 

 

另一个简单案例

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <title>公告页面管理</title>
    <script src="jquery-1.11.1.min.js"></script>
    <script src="jquery-ui.min.js"></script>
 <style>
  #draggable { width: 100px; height: 100px; padding: 0.5em; float: left; margin: 10px 10px 10px 0; }
  #droppable { width: 150px; height: 150px; padding: 0.5em; float: left; margin: 10px; }
  </style>
  <script>
  $(function() {
    $( "#draggable" ).draggable();
    $( "#droppable" ).droppable({
      drop: function( event, ui ) {
        $( this )
          .addClass( "ui-state-highlight" )
          .find( "p" )
            .html( "Dropped!" );
      }
    });
  });
  </script>
</head>
<body>
 
<div id="draggable" class="ui-widget-content">
  <p>请把我拖拽到目标处！</p>
</div>
 
<div id="droppable" class="ui-widget-header">
  <p>请放置在这里！</p>
</div>
 
 
</body>
</html>
