手风琴也是web页面中常见的一个控件，常常用在网站后台管理中，这里我们看看easyui中基本的手风琴设置。
1.先看看引用的资源
<meta charset="UTF-8" />
<link rel="stylesheet" href="jquery-easyui-1.3.5/themes/default/easyui.css" />
<link rel="stylesheet" href="jquery-easyui-1.3.5/themes/icon.css" />
<link rel="stylesheet" href="jquery-easyui-1.3.5/demo/demo.css" />
<script type="text/javascript" src="jquery-easyui-1.3.5/jquery.min.js"></script>
<script type="text/javascript" src="jquery-easyui-1.3.5/jquery.easyui.min.js"></script>
注意到这里并没有引用到其他的js只是两个基本的，一个是jquery.min.js，一个是jquery.easyui.min.js。
2.再看看html代码
<body>
<h2>Click on panel header to show its content.</h2>
<div class="demo-info">
<div class="demo-tip icon-tip"></div>
<div>Click on panel header to show its content.</div>
</div>
<div style="margin:10px 0"></div>
<div class="easyui-accordion" style="width:500px;height:300px;">
<div title="About" data-options="iconCls:'icon-ok'" style="overflow:auto;padding:10px;">
<h3 style="color:#0099FF;">Accordion for jQuery</h3>
<p>Accordion is a part of easyui framework for jQuery. It lets you define your accordion component on web page more easily.</p>
</div>
<div title="Help" data-options:"iconCls:'icon-help'" style="padding:10px">
<p>The accordion allows you to provide multiple panels and display one at a time. Each panel has built-in support for expanding and collapsing. Clicking on a panel header to expand or collapse that panel body. The panel content can be loaded via ajax by specifying a 'href' property. Users can define a panel to be selected. If it is not specified, then the first panel is taken by default.</p>
</div>
<div title="TreeMenu" data-options:"iconCls:'icon-search'" style="padding:10px">
<ul class="easyui-tree">
<li>
<span>Foods</span>
<ul>
<li>
<span>Fruits</span>
<ul>
<li>apple</li>
<li>orange</li>
</ul>
</li>
<li>
<span>Vegetables</span>
<ul>
<li>tomato</li>
<li>carrot</li>
<li>cabbage</li>
<li>potato</li>
<li>lettuce</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
</div>
</body>
说简单点一个基本的手风琴就是一个包含内部嵌套div的有class="easyui-accordion"的div，每个嵌套的div里面包含想要的元素。这里注意嵌套的div的属性title="About" data-options="iconCls:'icon-ok'" 这个就是定义每个格子的title和图标的。
这里看到<ul class="easyui-tree">这个是定义树形结构的，这是另外一个控件了。在后面的例子中。
总的来看还是很简单的。
