jQuery UI 庫文件官方下載： http://jqueryui.com/download

使用時，只需在工程中將 development-bundle 文件夾下的 themes 文件夾添加到新建 css 文件夾下，並將 ui 文件夾導入到工程中。然后在 html 文件中，按下列順序導入js文件：

1.拖動手柄

代碼如下：

  1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  2 <html xmlns="http://www.w3.org/1999/xhtml">
  3 <head>
  4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  5 <title>draggable組件</title>
  6 <script type="text/javascript" src="../js/jquery-1.7.2.js"></script>
  7 <script type="text/javascript" src="../ui/jquery.ui.core.js"></script>
  8 <script type="text/javascript" src="../ui/jquery.ui.widget.js"></script>
  9 <script type="text/javascript" src="../ui/jquery.ui.mouse.js"></script>
 10 <script type="text/javascript" src="../ui/jquery.ui.draggable.js"></script>
 11 <style type="text/css">
 12 .message_box {
 13     width:250px;
 14     height:150px;
 15     filter:dropshadow(color=#666666, offx=3, offy=3, positive=2);
 16     float:left;
 17 }
 18 #mask {
 19     position:absolute;
 20     top:0;
 21     left:0;
 22     width:expression(body.clientWidth);
 23     height:expression(body.clientHeight);
 24     background:#666;
 25     filter:ALPHA(opacity=60);
 26     z-index:1;
 27     visibility:hidden
 28 }
 29 .message {
 30     border:#036 solid;
 31     border-width:1 1 3 1;
 32     width:95%;
 33     height:95%;
 34     background:#fff;
 35     color:#036;
 36     font-size:12px;
 37     line-height:150%
 38 }
 39 .header {
 40     background:#036;
 41     height:22px;
 42     font-family:Verdana, Arial, Helvetica, sans-serif;
 43     font-size:12px;
 44     padding:3 5 0 5;
 45     color:#fff;
 46 }
 47 #message_box1 .header {
 48     cursor:move;
 49 }
 50 ul {
 51     margin-right:25px;
 52 }
 53 .header div {
 54     display:inline;
 55     width:150px;
 56 }
 57 .header span {
 58     float:right;
 59     display:inline;
 60     cursor:hand
 61 }
 62 fieldset {
 63     margin-bottom:5px;
 64 }
 65 </style>
 66 </head>
 67 <body>
 68 <fieldset>
 69   <legend>說明</legend>
 70   1、在"精彩專題推薦1"中只能通過拖動標題來移動，這是因為在handle屬性中定義該標題為拖動手柄。<br/>
 71   2、在"精彩專題推薦2"中除標題外都可以來作為拖動手柄，這是因為在cancel屬性定義該標題不具有拖動功能。
 72 </fieldset>
 73 <div id="message_box1" class="message_box" >
 74   <div class="message" >
 75     <div class="header">
 76       <div>精彩專題推薦1</div>
 77       <span>×</span></div>
 78     <ul>
 79       <li>用愛溫暖盲人心 </li>
 80       <li>莫奈 行走在光與色彩間的天才 </li>
 81       <li>秋寒來襲 謹防感冒 </li>
 82       <li>品茗聞香話茶道 </li>
 83       <li>秋季養生從食補做起 </li>
 84     </ul>
 85   </div>
 86 </div>
 87 <div id="message_box2" class="message_box" >
 88   <div class="message" >
 89     <div class="header">
 90       <div>精彩專題推薦2</div>
 91       <span>×</span></div>
 92     <ul>
 93       <li>用愛溫暖盲人心 </li>
 94       <li>莫奈 行走在光與色彩間的天才 </li>
 95       <li>秋寒來襲 謹防感冒 </li>
 96       <li>品茗聞香話茶道 </li>
 97       <li>秋季養生從食補做起 </li>
 98     </ul>
 99   </div>
100 </div>
101 <script language="javascript" type="text/javascript">
102 $(document).ready(function(){
103     $("#message_box1").draggable({handle:".header"});
104     $("#message_box2").draggable({cancel:".header",cursor:"move"});
105     $("ul li").disableSelection();
106     
107 });
108 </script>
109 </body>
110 </html>

2.Helper元素

代碼如下：

 1 <body>
 2 <fieldset>
 3   <legend>說明</legend>
 4   1、拖動"茄菲貓"時自身將隨鼠標一起移動，helper為original。<br/>
 5   2、拖動"多啦A夢"時自身原始位置不變，而是創建一個副本隨鼠標移動，helper為clone。還配合opacity屬性設置了透明度。<br/>
 6   3、拖動"阿童木"時將會出現一個自定義的helper，它是由helper的回調函數來定義的。
 7 </fieldset>
 8 <div id="message_box1" class="message_box" >
 9   <div class="message" >
10     <div class="header">
11       <div>茄菲貓</div>
12       <span>×</span></div>
13     <img src="images/jiafeimao.jpg" /> </div>
14 </div>
15 <div id="message_box2" class="message_box" >
16   <div class="message" >
17     <div class="header">
18       <div>多啦A夢</div>
19       <span>×</span></div>
20     <img src="images/duolaeim.jpg" /> </div>
21 </div>
22 <div id="message_box3" class="message_box" >
23   <div class="message" >
24     <div class="header">
25       <div>阿童木</div>
26       <span>×</span></div>
27     <img src="images/atongmu.jpg" /> </div>
28 </div>
29 <script language="javascript" type="text/javascript">
30 $(document).ready(function(){
31     $("#message_box1").draggable({helper: "original"});
32     $("#message_box2").draggable({opacity: 0.7, helper: "clone"});
33     $("#message_box3").draggable({
34         cursor: "move",
35         cursorAt: { top: -10, left: -10 },
36         helper: function( event ) {
37                 return $( "<div class='ui-widget-header'>這里是自定義helper</div>" );
38             }
39 
40         });
41 });
42 </script>
43 </body>

3.限制拖動區域

代碼如下：

 1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 2 <html xmlns="http://www.w3.org/1999/xhtml">
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 5 <title>draggable組件</title>
 6 <script language="javascript" src="js/jquery-1.4.2.min.js"></script>
 7 <script type="text/javascript" src="js/jquery.ui.core.js"></script>
 8 <script type="text/javascript" src="js/jquery.ui.widget.js"></script>

10 <script type="text/javascript" src="js/jquery.ui.draggable.js"></script>
11 <link href="CSS/base/jquery.ui.all.css" rel="stylesheet" type="text/css" />
12 <style type="text/css">
13 body {
14     font-size:14px;
15 }
16 #wrap {
17     clear:both;
18     margin: 10px auto 10px auto;
19     padding: 10px;
20     width: 620px;
21     height:150px;
22     background: #fff;
23     border: 5px solid #000;
24 }
25 .drag {
26     width:150px;
27     height:100px;
28     border: 2px solid #000;
29     float:left;
30     padding:5px;
31     margin: 0 10px 10px 0;
32 }
33 .miniDrag {
34     font-size:12px;
35     border: 2px solid #D6D6D6;
36     cursor:move
37 }
38 #box1 {
39     cursor: e-resize;
40 }
41 #box2 {
42     cursor: n-resize;
43 }
44 fieldset {
45     margin-bottom:5px;
46 }
47 </style>
48 </head>
49 <body>
50 <fieldset>
51   <legend>說明</legend>
52   1、box1和box2被限制只能在一個方向上拖動，由axis屬性定義。<br/>
53   2、box3、box4和box5則被限制在指定區域內，由containment屬性定義。
54 </fieldset>
55 <div id="box1" class="drag">我是box1，只能水平拖動。</div>
56 <div id="box2" class="drag">我是box2，只能垂直拖動。</div>
57 <div id="wrap">
58   <div id="box3" class="drag">我是box3，只能在這個容器內拖動。 </div>
59   <div id="box4" class="drag">我是box4，活動區域是整個窗口</div>
60   <div  class="drag">我是box
61     <div id="box5" class="miniDrag">我是box5，能在我的父容器內活動</div>
62   </div>
63 </div>
64 <script type="text/javascript" language="javascript">
65 $(document).ready(function(){
66     $("#box1").draggable({axis:"x"});
67     $("#box2").draggable({axis:"y"});
68     $("#box3").draggable({containment: "#wrap", scroll: false,cursor:"move"});
69     $("#box4").draggable({containment: "window",cursor:"move"});
70     $("#box5").draggable({containment: "parent",cursor:"move"});
71 });
72 </script>
73 </body>
74 </html>

4.自動吸附

代碼如下：

 1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 2 <html xmlns="http://www.w3.org/1999/xhtml">

34     border: 1px solid #000;
35     float:left;
36     margin: 0 20px 0 0;
37     background:#FFF;
38 }
39 
40 </style>
41 </head>
42 <body>
43 <h1>設置可拖動元素的吸附能力</h1>
44 <div id="wrap" >
45   <div id="box1" class="drag">box1,自動吸附到所有可拖動對象</div>
46   <div id="box2" class="drag">box2,僅可吸附到父容器</div>
47   <div id="box3" class="drag">box3,僅可吸附到父容器的內邊</div>

49   <div id="box5" class="drag">box5,按40×40網格自動吸附</div>
50 </div>
51 <script type="text/javascript" language="javascript">
52 $(document).ready(function(){
53         $( "#box1" ).draggable({ snap: true });
54         $( "#box2" ).draggable({ snap: "#wrap" });
55         $( "#box3" ).draggable({ snap: "#wrap", snapMode: "inner" });
56         $( "#box4" ).draggable({ grid: [ 20,20 ] });
57         $( "#box5" ).draggable({ grid: [ 40, 40 ] });
58 });
59 </script>
60 </body>
61 </html>

5.重設拖動后的元素

 75   1、拖動"茄菲貓"結束時，自身將從鼠標位置自動返回原始位置。<br/>
 76   2、拖動"多啦A夢"結束時，副本將從鼠標位置自動返回原始位置。<br/>
 77   3、拖動"阿童木"結束時，自身將從鼠標位置自動返回原始位置。在這里可以設置返回間隔（單位：毫秒）
