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; }
