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。
