jQuery EasyUI 树形菜单 – 创建异步树形菜单
为了创建异步的树形菜单(Tree),每一个树节点必须要有一个 \’id\’ 属性,这个将提交回服务器去检索子节点数据。

创建树形菜单(Tree)
<ul url=\"tree2_getdata.php\"> </ul>
服务器端代码
$id = isset($_POST[\'id\']) ? intval($_POST[\'id\']) : 0;
include \'conn.php\';
$result = array();
$rs = mysql_query(\"select * from nodes where parentId=$id\");
while($row = mysql_fetch_array($rs)){
$node = array();
$node[\'id\'] = $row[\'id\'];
$node[\'text\'] = $row[\'name\'];
$node[\'state\'] = has_child($row[\'id\']) ? \'closed\' : \'open\';
array_push($result,$node);
}
echo json_encode($result);
function has_child($id){
$rs = mysql_query(\"select count(*) from nodes where parentId=$id\");
$row = mysql_fetch_array($rs);
return $row[0] > 0 ? true : false;
}
