本篇介绍Accordion组件（类似手风琴可以折叠的UI组件）。

基本用法

jQuery Accordion UI组件可以把一个包含有具有Header (标题头）和Content（内容）对的容器转变成Accordion组件。
比如如下一个Id=”accordion”Div HTML元素。

1 <div id="accordion">
2     <h1>Section 1</h1>
3     <div>
4         <p>Description 1</p>
5     </div>
6     <h2>Section 2</h2>
7     <div>
8         <p>Description 3</p>
9     </div>
10     <h3>Section 3</h3>
11     <div>
12         <p>Description 3</p>
13         <ul>
14             <li>List item one</li>
15             <li>List item two</li>
16             <li>List item three</li>
17         </ul>
18     </div>
19 </div>

对于＜div id=”accordion”>里面的元素，According允许使用任意的标记，只要是一个Header紧接着一个Content，比如上面的H3，你可以换成H1，H2等其它标记，或者通过Header选项来配置。
有了这样的HTML元素，然后对其使用Accordion方法，就将该HTML元素变成Accordion 样式了

1 <script>
2     $("#accordion").accordion();
3 </script>

本例完整代码如下：

1 <!doctype html>
2 <html lang="en">
3 <head>
4     <meta charset="utf-8" />
5     <title>jQuery UI Demos</title>
6     <link rel="stylesheet" href="themes/trontastic/jquery-ui.css" />
7     <script src="scripts/jquery-1.9.1.js"></script>
8     <script src="scripts/jquery-ui-1.10.1.custom.js"></script>
9  
10     <script>
11         $(function () {
12  
13         });
14     </script>
15 </head>
16 <body>
17     <div id="accordion">
18         <h1>Section 1</h1>
19         <div>
20             <p>Description 1</p>
21         </div>
22         <h2>Section 2</h2>
23         <div>
24             <p>Description 3</p>
25         </div>
26         <h3>Section 3</h3>
27         <div>
28             <p>Description 3</p>
29             <ul>
30                 <li>List item one</li>
31                 <li>List item two</li>
32                 <li>List item three</li>
33             </ul>
34         </div>
35     </div>
36  
37     <script>
38         $("#accordion").accordion();
39     </script>
40 </body>
41 </html>

20130314001折叠内容

Accordion 组件缺省情况下总有一项内容是展开的，如说图Section1的内容是可见的，点击其它部分的标题，该部分内容可见，但无法将所有内容都折叠起来，如果要支持所有部分都可以折叠，可以通过配置collapsible 属性，如：

1 $(function() {
2     $( "#accordion" ).accordion({
3       collapsible: true
4     });
5   });

20130314002自定义图标

可以自定义Accordion 组件标题前的图标，缺省的图标为箭头（未展开是箭头向右，展开时向下），使用jQuery CSS框架中定义的类或是通过自定义背景图像类，可以重新配置这两个图标：

1 $(function() {
2     var icons = {
3       header: "ui-icon-circle-arrow-e",
4       activeHeader: "ui-icon-circle-arrow-s"
5     };
6     $( "#accordion" ).accordion({
7       icons: icons
8     });
9     $( "#toggle" ).button().click(function() {
10       if ( $( "#accordion" ).accordion( "option", "icons" ) ) {
11         $( "#accordion" ).accordion( "option", "icons", null );
12       } else {
13         $( "#accordion" ).accordion( "option", "icons", icons );
14       }
15     });
16   });

20130314003设置HeightStyle

因为Accordion由“Block级”元素组成（可以参加CSS的display)，因此它缺省在水平方向占据父元素的宽度，为了在高度方向也能充满其父容器，可以通过配置heightStyle 为fill .HeightStyle 可以使用的值如下：

  • "auto": 所有Panel使用最高的那个Panel的高度.
  • "fill": 根据父容器的高度来填充.
  • "content": 每个Penel的高度取决于其内容.
1 <!doctype html>

11         #accordion-resizer {
12             padding: 10px;
13             width: 350px;
14             height: 300px;
15         }
16     </style>
17     <script>
18         $(function () {
19             $("#accordion").accordion({
20                 heightStyle: "fill"
21             });
22         });
23         $(function () {
24             $("#accordion-resizer").resizable({
25                 minHeight: 140,
26                 minWidth: 200,
27                 resize: function () {
28                     $("#accordion").accordion("refresh");
29                 }
30             });
31         });
32     </script>

106     </div>

20130314004鼠标移动式自动打开内容

缺省情况下，打开Accordion某个部分内容，是点击该部分标题，如果需要实现移动鼠标到该部分自动展开内容，可以设置event属性，例如：

1 $(function () {
2     $("#accordion").accordion({
3         event: "mouseover"
4     });
5 });

支持调整顺序

使用sortable方法允许重新调整Accordion每个部分的顺序，可以通过拖放的方法调整顺序：

1 <!doctype html>
2 <html lang="en">
3 <head>
4     <meta charset="utf-8" />
5     <title>jQuery UI Demos</title>
6     <link rel="stylesheet" href="themes/trontastic/jquery-ui.css" />
7     <script src="scripts/jquery-1.9.1.js"></script>
8     <script src="scripts/jquery-ui-1.10.1.custom.js"></script>
9     <style>
10         /* IE has layout issues when sorting (see #5413) */
11         .group {
12             zoom: 1;
13         }
14     </style>
15     <script>
16         $(function () {
17             $("#accordion").accordion({
18                 header: "> div > h3",
19                 collapsible: true
20             }).sortable({
21                 axis: "y",
22                 handle: "h3",
23                 stop: function (event, ui) {
24                     // IE doesn't register the blur when sorting
25                     // so trigger focusout handlers to remove .ui-state-focus
26                     ui.item.children("h3").triggerHandler("focusout");
27                 }
28             });;
29         });
30     </script>
31 </head>
32 <body>
33     <div id="accordion">
34         <div class="group">
35             <h3>Section 1</h3>
36  
37             <div>
38                 <p>Description 1</p>
39             </div>
40         </div>
41         <div class="group">
42             <h3>Section 2</h3>
43             <div>
44                 <p>Description 2</p>
45             </div>
46         </div>
47         <div class="group">
48             <h3>Section 3</h3>
49  
50             <div>
51                 <p>Description 3</p>
52                 <ul>
53                     <li>List item one</li>
54                     <li>List item two</li>
55                     <li>List item three</li>
56                 </ul>
57             </div>
58         </div>
59         <div class="group">
60             <h3>Section 4</h3>
61  
62             <div>
63                 <p>Description 4</p>
64             </div>
65         </div>
66     </div>
67  
68 </body>
69 </html>

20130314005注意，这里使用Header属性，标题部分由div ,h3 共同构成。
