先放個最終的效果圖：
然後是程式碼：
html檔案：
<body>
<h1>TreeGrid</h1>
<div>
<a id="consle" href="#">consle</a>
</div>
<table id="test" title="Folder Browser" style="width:400px;height:300px" >
</table>
</body>

說明：沒什麼內容，標題，然後是一個表格，我為了做些測試放了按鈕consle，不用刪除即可，當然要引用幾個js檔案和css檔：
<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!">

<script type="text/javascript" src="http://www.jeasyui.com/easyui/jquery.easyui.min.js"></script>
<script type="text/javascript" src="ws.js"></script>

接著是js檔：
$(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);
}登入後複製
說明：呼叫了easyUI的treegrid，為了顯示checkbox，對第一列做了個formatter，為了展示效果綁定了取得選取checkbox的事件，不用可以去掉，也可以去掉alert，改為其他的事件處理函數。
最後附上資料json檔案：

"name":"C",
"size":"",
"date":"02/19/2010",

說明：
這個json直接從官網down的，隨處可見，也可改為url方式。
