先放个最终的效果图：
然后是代码：
html文件：
<body> <h1>TreeGrid</h1> <div> <a id="consle" href="#">consle</a> </div> <table id="test" title="Folder Browser" > </table> </body>
说明：没什么内容，标题，然后是一个表格，我为了做些测试放了个按钮consle，不用删掉即可，当然要引用几个js文件和css文件：
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="keywords" content="jquery,ui,easy,easyui,web"> <meta name="description" content="easyui help you build your web page easily!"> <title>jQuery EasyUI Demo</title> <link rel="stylesheet" type="text/css" href="http://www.jeasyui.com/easyui/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="http://www.jeasyui.com/easyui/themes/icon.css"> <script type="text/javascript" src="http://code.jquery.com/jquery-1.6.1.min.js"></script> <script type="text/javascript" src="http://www.jeasyui.com/easyui/jquery.easyui.min.js"></script> <script type="text/javascript" src="ws.js"></script>
接着是js文件：
$(function(){ $('#test').treegrid({ url:"data/treegrid_data.json", idField:'id', treeField:'name', animate:"true", rownumbers:"true", columns:[[ {title:'Task Name',field:'name',formatter:function(value,rowData,rowIndex){ return " " + rowData.name; },width:180}, {field:'size',title:'Persons',width:60,align:'right'}, {field:'date',title:'Begin Date',width:80} ]] }); $("#consle").bind("click",consleclick) }); function set_power_status(){ var idList = ""; $("input:checked").each(function(){ var id = $(this).attr("id"); if(id.indexOf("ceshi_")>-1) idList += id.replace("ceshi_",'')+','; }) alert(idList); } function consleclick(){ var node = $('#test').treegrid('expandAll',2); }
说明：调用了easyUI的treegrid，为了显示checkbox，对第一列做了个formatter，为了展示效果绑定了取得选中checkbox的事件，不用可以去掉，也可以去掉alert，更改为其他的事件处理函数。
最后附上数据json文件：
[{ "id":1, "name":"C", "size":"", "date":"02/19/2010", "children":[{ "id":2, "name":"Program Files", "size":"120 MB", "date":"03/20/2010", "children":[{ "id":21, "name":"Java", "size":"", "date":"01/13/2010", "state":"closed", "children":[{ "id":211, "name":"java.exe", "size":"142 KB", "date":"01/13/2010" },{ "id":212, "name":"jawt.dll", "size":"5 KB", "date":"01/13/2010" }] },{ "id":22, "name":"MySQL", "size":"", "date":"01/13/2010", "state":"closed", "children":[{ "id":221, "name":"my.ini", "size":"10 KB", "date":"02/26/2009" },{ "id":222, "name":"my-huge.ini", "size":"5 KB", "date":"02/26/2009" },{ "id":223, "name":"my-large.ini", "size":"5 KB", "date":"02/26/2009" }] }] },{ "id":3, "name":"eclipse", "size":"", "date":"01/20/2010", "children":[{ "id":31, "name":"eclipse.exe", "size":"56 KB", "date":"05/19/2009" },{ "id":32, "name":"eclipse.ini", "size":"1 KB", "date":"04/20/2010" },{ "id":33, "name":"notice.html", "size":"7 KB", "date":"03/17/2005" }] }] }]
说明：
这个json直接从官网down的，随处可见，也可改为url方式。
